The compatibility contract

We deliver the most QuickBooks Online compatibility we can, and we're honest about the rest. Reads are almost entirely compatible; writes are where QuickBooks Desktop's quirks show up. Every partial or unsupported case below comes with the exact fix.

This page is the full entity matrix — every QBO Accounting API entity we track, whether live, planned, or a documented gap. Jump to an entity from the tables below, or read IDs, SyncToken & sparse updates for the cross-cutting rules.

Entity matrix

Every QBO Accounting API entity we track, with an honest verdict and a one-line Desktop reality check. Use this page to answer "does TenkeyBridge cover what I use?" in under a minute.

Legend — Full: works unchanged · Partial: common cases work, see the entity section · Full (read-only): reads work; no write path · Planned: real Desktop analog, not yet shipped · Stretch: lower-priority planned · Never: no honest Desktop equivalent · Future: platform ops after the entity matrix.

Sales

Entity	Verdict	Headline
CreditMemo	Partial	Invoice twin — Balance and RemainingCredit both map from Desktop CreditRemaining
Customer	Full	Sub-customer maps to Desktop Customer:Job
Estimate	Partial	Same shape as Invoice; no expiration/acceptance tracking
Invoice	Partial	Line model, tax, discount, linked txns, and custom fields
Item	Partial	One Item becomes several Desktop item types
Payment	Partial	Applying a payment to specific invoices
RefundReceipt	Partial	Card refunds of applied credits only (ARRefundCreditCard) — not general item-line refunds
SalesReceipt	Partial	Same as Invoice + deposit account

Purchasing

Entity	Verdict	Headline
Bill	Full	Account vs. item expense lines map cleanly
BillPayment	Partial	Fans out to BillPaymentCheck / BillPaymentCreditCard by PayType
Purchase	Partial	Fans out to Check / CreditCardCharge / CreditCardCredit by PaymentType
PurchaseOrder	Partial	Non-posting; item lines only — never touches the GL on either side
Vendor	Full	1099 / tax-ID field naming only
VendorCredit	Partial	Bill mirror image — expense and item lines

Banking

Entity	Verdict	Headline
Account	Full	AccountType / AccountSubType enum mapping
Deposit	Partial	Undeposited Funds → bank via LinkedTxn or manual DepositLineDetail
JournalEntry	Partial	Debit/Credit lines split across Desktop JournalDebitLine / JournalCreditLine
Transfer	Full	Bank-to-bank transfer between two accounts

Lists & config

Entity	Verdict	Headline
Class	Full	Hierarchical Class list; SubClass/FullyQualifiedName from Desktop Sublevel/FullName
CompanyCurrency	Full (read-only)	Desktop CurrencyQuery list; empty when multicurrency is off (statusCode 3250, confirmed live, and 3170 both normalized to [])
CustomerType	Full (read-only)	Read/query only — QBO CustomerType is read-only via the API; Desktop hierarchy is not exposed
Employee	Full (read-only)	Read/query only — no Desktop write path this release; payroll aggregates out of scope
ExchangeRate	Partial	Projected from CurrencyRet.ExchangeRate + AsOfDate; one row per currency that carries a rate; empty when multicurrency is off (statusCode 3250, confirmed live, and 3170 both normalized to [])
PaymentMethod	Partial	Create only — Desktop has no PaymentMethodMod; Type coarsens Desktop's fine enum to CREDIT_CARD
TaxAgency	Full (read-only)	Read-only projection — Vendors referenced by any ItemSalesTax.TaxVendorRef (no native Desktop TaxAgency list)
TaxCode	Full	Desktop SalesTaxCode list (TAX/NON); Name max 3 chars (fail-loud, never truncated); a plain taxable/non-taxable flag pair, not a rate container
TaxRate	Full (read-only)	Read-only (parity with QBO) — Desktop ItemSalesTaxQuery; each single rate item is a TaxRate; sales-tax groups are not projected as TaxRates
Term	Partial	Merged StandardTerms + DateDrivenTerms; Type STANDARD
TimeActivity	Partial	Employee time only; Duration compiled from Hours/Minutes or a StartTime/EndTime span

Company

Entity	Verdict	Headline
CompanyInfo	Full (read-only)	Read-only; Id equals the realm ID, no Desktop write path
Preferences	Partial	Read-only singleton (Id=1); honest subset of Desktop PreferencesQuery groups

Planned (Desktop analog exists)

Entity	Verdict	Headline
Budget	Planned	qbXML has no Budget records, but budget figures are readable through BudgetSummaryReportQuery — a read-only Budget synthesized from that report is planned; budget writes stay in the Desktop UI forever.

Never — no Desktop equivalent

Entity	Verdict	Headline
Attachable	Never	QuickBooks Desktop's qbXML API has no attachments interface — the word 'Attachment' does not occur anywhere in the qbxmlops130 message set.
Department	Never	QBO Departments (locations) have no Desktop equivalent — the only 'Department'/'Location' strings in qbXML are free-text fields on Employee, FixedAsset, and Lead, and Desktop's one real dimensional list (Class) is already exposed faithfully as Class.
JournalCode	Never	France-only QBO regulatory feature; not applicable to Desktop — 'JournalCode' occurs nowhere in the qbxmlops130 message set.
RecurringTransaction	Never	Desktop's memorized transactions are not exposed by qbXML — there is no message to list, read, create, or execute them.
ReimburseCharge	Never	QBO's billable-charge object has no Desktop record behind it — in qbXML, billability is a status flag (BillableStatus) on the source expense/item/time lines, never a standalone charge you can query.
TaxClassification	Never	Cloud automated-sales-tax concept with no Desktop counterpart — Desktop's tax model is explicit tax items and codes, all of which TenkeyBridge exposes.
TaxService	Never	Cloud AST onboarding operation with no Desktop counterpart — 'TaxService' occurs nowhere in the qbxmlops130 message set.

Platform

Entity	Verdict	Headline
Batch	Full	Batch envelope — up to 30 create/update/delete/query operations in one request, executed sequentially with per-item faults.
CDC	Full (read-only)	Change Data Capture — one poll returns changed + deleted records across entities.
Reports	Partial	Five QBO-compatible reports translated live from Desktop's report engine.

Entity detail

CreditMemo

Verdict: Partial · Read: Full · Write: Partial — Invoice twin — Balance and RemainingCredit both map from Desktop CreditRemaining

QBO field	Support	Notes
CustomerMemo	Full	Maps to Desktop CustomerMsgRef by FullName; the message must already exist as a Desktop customer message. Updatable via sparse update (#55).
Line	Partial	Same DetailType support as Invoice: SalesItemLineDetail, GroupLineDetail, and DescriptionOnly map cleanly; DiscountLineDetail requires a Desktop discount item; other DetailTypes return UNSUPPORTED_BY_DESKTOP. Group lines read back as GroupLineDetail without nested line expansion; Desktop discount lines read back as regular item lines referencing the discount item. Updates carrying Line replace the entire line table: every line is re-created with a new line Id and lines omitted from the update are deleted by Desktop (v1 full replacement, #55).
TxnTaxDetail	Partial	Set TxnTaxCodeRef explicitly; computed TotalTax alone is rejected. Updatable via sparse update (#55).
LinkedTxn	Partial	Read-only; reflects applied payments/credits, ignored on write — same as QBO.
TotalAmt	Full	Read-only, mapped from Desktop TotalAmount.
Balance	Full	Read-only remaining unapplied credit; mapped from Desktop CreditRemaining.
RemainingCredit	Full	Read-only — total credit still available to apply. A distinct QBO field, not an alias of Balance; both map from Desktop's single CreditRemaining since Desktop has only the one figure.
ApplyTaxAfterDiscount	None	UNSUPPORTED_BY_DESKTOP — Desktop credit memos have no ApplyTaxAfterDiscount toggle. Control tax via per-line TaxCodeRef / TxnTaxDetail.TxnTaxCodeRef instead.

Everything else listed as full works unchanged.

Invoice

Verdict: Partial · Read: Full · Write: Partial — Line model, tax, discount, linked txns, and custom fields

QBO field	Support	Notes
CustomerMemo	Full	Maps to Desktop CustomerMsgRef by FullName; the message must already exist as a Desktop customer message. Updatable via sparse update (#55).
Line	Partial	SalesItemLineDetail, GroupLineDetail, and DescriptionOnly map cleanly; line-level ClassRef and ServiceDate are populated on read; DiscountLineDetail requires a Desktop discount item referenced via DiscountLineDetail.ItemRef; other DetailTypes (e.g. SubTotalLineDetail) return UNSUPPORTED_BY_DESKTOP. Group lines read back as GroupLineDetail without nested line expansion; Desktop discount lines read back as regular item lines referencing the discount item. Updates carrying Line replace the entire line table: every line is re-created with a new line Id and lines omitted from the update are deleted by Desktop (v1 full replacement, #55).
TxnTaxDetail	Partial	Set TxnTaxCodeRef explicitly on write; computed TotalTax alone is rejected. On read: TotalTax, TxnTaxCodeRef (from ItemSalesTaxRef), and TaxLine[{Amount, TaxLineDetail{TaxRateRef, TaxPercent}}] from SalesTaxTotal/ItemSalesTaxRef/SalesTaxPercentage. NetAmountTaxable is never returned (Desktop has no taxable basis). Updatable via sparse update (#55).
LinkedTxn	Full	Populated on read from LinkedTxnRet when IncludeLinkedTxns is requested (automatic). Desktop ReceivePayment → QBO Payment; links to Desktop-only transaction types (SalesOrder, ItemReceipt, …) are omitted rather than guessed at. Accepted and ignored on write — same as QBO treats it as read-only.
CustomField	Partial	Name/StringValue populated from Desktop custom fields (DataExt); DefinitionId not available from Desktop; read-only for now. Accepted and ignored on write.
TotalAmt	Full	Read-only, computed by Desktop as Subtotal + SalesTaxTotal.
Balance	Full	Read-only, computed by Desktop as BalanceRemaining.
CurrencyRef	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.

Item

Verdict: Partial · Read: Partial · Write: None — One Item becomes several Desktop item types

QBO field	Support	Notes
FullyQualifiedName	Full	Read-only in this release.
Active	Full	Read-only in this release.
Type	Partial	Service, NonInventory, Inventory, Group map; other Desktop types are omitted from query results.
Description	Full	Read-only in this release.
UnitPrice	Full	Read-only in this release.
Sku	Partial	QBO Sku ⇄ Desktop ManufacturerPartNumber — Desktop has no first-class SKU field; barcode (Advanced Inventory) is intentionally not used. Read-only in this release.
QtyOnHand	Full	Read-only in this release.
IncomeAccountRef	Full	Read-only in this release.
ExpenseAccountRef	Partial	Inventory: COGSAccountRef. Two-sided Service/NonInventory (SalesAndPurchase): ExpenseAccountRef. One-sided Service/NonInventory have no expense account.

• Name

Query support

Standard SELECT * FROM Item with the shared WHERE / STARTPOSITION / MAXRESULTS subset documented in IDs, SyncToken & sparse updates. Anything outside that subset returns UNSUPPORTED_QUERY.

Not supported

• Item types other than Service, NonInventory, Inventory, and Group (assemblies, discounts, sales tax items, payment items, fixed assets, other charge, subtotal) — UNSUPPORTED_BY_DESKTOP: Omitted from query results; a direct get by id on one of these Desktop items returns a 422 UNSUPPORTED_BY_DESKTOP fault.
• Item create/update — UNSUPPORTED_BY_DESKTOP: Lands in a later release.

Payment

Verdict: Partial · Read: Full · Write: Partial — Applying a payment to specific invoices

QBO field	Support	Notes
PaymentRefNum	Full	Desktop RefNumber. Query filtering by PaymentRefNum is not supported yet — query by Id or date range.
DepositToAccountRef	Full	Omit to use Desktop's Undeposited Funds preference, same as QBO.
Line	Partial	LinkedTxn applications to Invoices only; no Line means an unapplied payment (IsAutoApply=false). CreditMemo/Deposit applications land later. AppliedToTxnRet.TxnDate/RefNumber/BalanceRemaining have no honest home in QBO Payment.Line.LinkedTxn ({TxnId, TxnType} only) and are not projected — re-fetch the invoice for balance/date/doc number.
UnappliedAmt	Full	Read-only; Desktop UnusedPayment.
CustomField	Partial	Name/StringValue populated from Desktop custom fields (DataExt); DefinitionId not available from Desktop; read-only for now. Accepted and ignored on write.
CurrencyRef	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.
ExchangeRate	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.
ProcessPayment	Partial	Accepted and ignored — TenkeyBridge never initiates card processing.
TxnNumber	None	UNSUPPORTED_BY_DESKTOP — Desktop's internal auto-increment TxnNumber has no QBO equivalent and is not surfaced.
UnusedCredits	None	UNSUPPORTED_BY_DESKTOP — Desktop UnusedCredits (unapplied credit memos available to the customer) is distinct from UnappliedAmt/UnusedPayment; no honest home on Payment — belongs on CreditMemo.Balance.

Everything else listed as full works unchanged.

RefundReceipt

Verdict: Partial · Read: Partial · Write: Partial — Card refunds of applied credits only (ARRefundCreditCard) — not general item-line refunds

QBO field	Support	Notes
DepositToAccountRef	Full	Maps to Desktop RefundFromAccountRef.
PaymentMethodRef	Full	Must be a credit-card payment method in the company file.
Line	Partial	LinkedTxn credit-memo applications → RefundAppliedToTxnAdd only. At least one Line is required on create — Desktop's ARRefundCreditCardAdd requires one or more RefundAppliedToTxnAdd; an empty/missing Line array fails loud rather than sending Desktop an invalid request. SalesItemLineDetail / item-line refunds return UNSUPPORTED_BY_DESKTOP — use CreditMemo + payment/refund pair instead (see CreditMemo).
TotalAmt	Full	Read-only from Desktop TotalAmount.
CurrencyRef	None	UNSUPPORTED_BY_DESKTOP — Multicurrency not yet supported.
ExchangeRate	None	UNSUPPORTED_BY_DESKTOP — Multicurrency not yet supported.

• Update / sparse update — UNSUPPORTED_BY_DESKTOP: ARRefundCreditCard has no Mod path in this release.

SalesReceipt

Verdict: Partial · Read: Full · Write: Partial — Same as Invoice + deposit account

QBO field	Support	Notes
CustomerMemo	Full	Maps to Desktop CustomerMsgRef by FullName; the message must already exist as a Desktop customer message. Updatable via sparse update (#55).
Line	Partial	SalesItemLineDetail, GroupLineDetail, and DescriptionOnly map cleanly; line-level ClassRef and ServiceDate are populated on read; DiscountLineDetail requires a Desktop discount item referenced via DiscountLineDetail.ItemRef; other DetailTypes (e.g. SubTotalLineDetail) return UNSUPPORTED_BY_DESKTOP. Group lines read back as GroupLineDetail without nested line expansion; Desktop discount lines read back as regular item lines referencing the discount item. Updates carrying Line replace the entire line table: every line is re-created with a new line Id and lines omitted from the update are deleted by Desktop (v1 full replacement, #55).
TxnTaxDetail	Partial	Set TxnTaxCodeRef explicitly on write; computed TotalTax alone is rejected. On read: TotalTax, TxnTaxCodeRef, and TaxLine[{Amount, TaxLineDetail{TaxRateRef, TaxPercent}}]. NetAmountTaxable never returned. Updatable via sparse update (#55).
LinkedTxn	Partial	Desktop SalesReceiptQueryRq has no IncludeLinkedTxns and SalesReceiptRet carries no LinkedTxnRet (qbXML 13.0) — never populated on read. Accepted and ignored on write.
CustomField	Partial	Name/StringValue populated from Desktop custom fields (DataExt); DefinitionId not available from Desktop; read-only for now. Accepted and ignored on write.
TotalAmt	Full	Read-only; Desktop computes it.
CurrencyRef	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.

Bill

Verdict: Full · Read: Full · Write: Full — Account vs. item expense lines map cleanly

QBO field	Support	Notes
SalesTermRef	Full	Desktop TermsRef.
Line	Full	Account-based and item-based expense lines; other line types return UNSUPPORTED_BY_DESKTOP. Sparse updates cannot modify lines/memo/tax yet. Both AccountBasedExpenseLineDetail.ClassRef and ItemBasedExpenseLineDetail.ClassRef are read/written, mapping to Desktop ExpenseLineAdd/ExpenseLineRet and ItemLineAdd/ItemLineRet ClassRef respectively — on ExpenseLineAdd, ClassRef sits in OSR position (AccountRef < Amount < Memo < CustomerRef < ClassRef).
TotalAmt	Full	Read-only, computed by Desktop as AmountDue.
Balance	Full	Read-only, as in QBO.
CustomField	Partial	Name/StringValue populated from Desktop custom fields (DataExt); DefinitionId not available from Desktop; read-only for now. Accepted and ignored on write.
CurrencyRef	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.
ExchangeRate	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.
LinkedTxn	None	UNSUPPORTED_BY_DESKTOP — QBO Bill has no paid-by LinkedTxn field. Desktop may return LinkedTxnRet when IncludeLinkedTxns is set, but there is no honest QBO home — not projected.

Everything else listed as full works unchanged.

BillPayment

Verdict: Partial · Read: Full · Write: Partial — Fans out to BillPaymentCheck / BillPaymentCreditCard by PayType

QBO field	Support	Notes
PayType	Full	Check → BillPaymentCheck*; CreditCard → BillPaymentCreditCard*. Updates: Check family only — qbXML has no BillPaymentCreditCardMod, so credit-card-family updates fail loud with UNSUPPORTED_BY_DESKTOP (#75); delete and re-create instead.
VendorRef	Full	Maps to Desktop PayeeEntityRef.
TotalAmt	Full	Read-only from Desktop Amount; write-ignored on create/update — neither BillPaymentCheckAdd nor BillPaymentCreditCardAdd has a top-level Amount element in the OSR, Desktop derives it from the summed AppliedToTxnAdd/PaymentAmount values instead.
CheckPayment	Full	CheckPayment.BankAccountRef ⇄ BankAccountRef.
CreditCardPayment	Full	CreditCardPayment.CCAccountRef ⇄ CreditCardAccountRef.
PrintStatus	Partial	Check flavor only; ⇄ IsToBePrinted. BillPaymentCheckAdd requires IsToBePrinted OR RefNumber (Desktop OSR); when a create supplies neither PrintStatus nor DocNumber, TenkeyBridge synthesizes IsToBePrinted=false so the Add stays schema-valid.
Line	Partial	LinkedTxn bills → AppliedToTxnAdd; additional LinkedTxn VendorCredit → SetCredit. Sparse updates cannot modify lines yet.
CurrencyRef	None	UNSUPPORTED_BY_DESKTOP — Multicurrency not yet supported.
ExchangeRate	None	UNSUPPORTED_BY_DESKTOP — Multicurrency not yet supported.

Everything else listed as full works unchanged.

Purchase

Verdict: Partial · Read: Full · Write: Partial — Fans out to Check / CreditCardCharge / CreditCardCredit by PaymentType

QBO field	Support	Notes
PaymentType	Partial	Check and CreditCard map to Desktop families; Cash is partial (maps to Check against the supplied bank/petty-cash AccountRef — Desktop has no separate cash purchase type).
Credit	Full	true + PaymentType CreditCard → CreditCardCredit*; false/omitted → CreditCardCharge*.
AccountRef	Full	Bank account (Check/Cash) or credit-card account (CreditCard).
EntityRef	Full	Maps to Desktop PayeeEntityRef (Customer/Vendor/Employee).
PrintStatus	Partial	NeedToPrint/PrintComplete ⇄ IsToBePrinted (Check family).
Line	Full	AccountBasedExpenseLineDetail and ItemBasedExpenseLineDetail via shared Bill line machinery. Sparse updates cannot modify lines yet.
TotalAmt	Full	Read-only from Desktop Amount.
CurrencyRef	None	UNSUPPORTED_BY_DESKTOP — Multicurrency not yet supported.
ExchangeRate	None	UNSUPPORTED_BY_DESKTOP — Multicurrency not yet supported.

Everything else listed as full works unchanged.

Full fields

• TxnDate

Query support

• List query STARTPOSITION > 1 across multi-type families — UNSUPPORTED_QUERY: Deep iterator pagination uses the primary Check family only; page-1 and filtered queries merge Check + CreditCardCharge + CreditCardCredit (per-type order concatenated).

Not supported

• PaymentType outside Check/Cash/CreditCard — UNSUPPORTED_BY_DESKTOP: Only Check, Cash (→Check), and CreditCard map to Desktop purchase families.
• List query STARTPOSITION > 1 across multi-type families — UNSUPPORTED_QUERY: Deep iterator pagination uses the primary Check family only; page-1 and filtered queries merge Check + CreditCardCharge + CreditCardCredit (per-type order concatenated).

PurchaseOrder

Verdict: Partial · Read: Full · Write: Partial — Non-posting; item lines only — never touches the GL on either side

QBO field	Support	Notes
Line	Partial	ItemBasedExpenseLineDetail only (PurchaseOrderLineAdd). AccountBasedExpenseLineDetail returns UNSUPPORTED_BY_DESKTOP. ReceivedQty maps from ReceivedQuantity on read (read-only). Sparse updates cannot modify lines yet.
TotalAmt	Full	Read-only from Desktop TotalAmount.
POStatus	Partial	Open/Closed map to Desktop IsManuallyClosed, a Mod-only element — PurchaseOrderAdd has no IsManuallyClosed at all. Create with POStatus Open (or omitted) works; POStatus Closed on create returns UNSUPPORTED_BY_DESKTOP (create the PO open, then close it via an update). Closing via sparse update is not wired yet — POStatus is effectively read-only through TenkeyBridge until that lands.
APAccountRef	None	UNSUPPORTED_BY_DESKTOP — Purchase orders are non-posting — there is no AP account on Desktop POs.

Standard SELECT * FROM PurchaseOrder with the shared WHERE / STARTPOSITION / MAXRESULTS subset documented in IDs, SyncToken & sparse updates. Anything outside that subset returns UNSUPPORTED_QUERY.

Not supported

• AccountBasedExpenseLineDetail on a PurchaseOrder line — UNSUPPORTED_BY_DESKTOP: Desktop PO lines are item-only. Use ItemBasedExpenseLineDetail, or post a Bill/Purchase for account expenses.
• POStatus Closed on create — UNSUPPORTED_BY_DESKTOP: Desktop's PurchaseOrderAdd has no IsManuallyClosed element — a PO can't be created already closed. Create it open, then close it via an update.

Account

Verdict: Full · Read: Full · Write: Full — AccountType / AccountSubType enum mapping

QBO field	Support	Notes
ParentRef	Full	Becomes a Desktop sub-account; FullName is colon-delimited.
AccountType	Partial	Mapped per the COMPATIBILITY.md appendix; unmapped values return 422 UNMAPPED_ACCOUNT_TYPE. Desktop-only Non-Posting appears on reads.
AccountSubType	Partial	Accepted and ignored — Desktop has no account subtype; reads never return one.
FullyQualifiedName	Full	Read-only, derived by Desktop.

JournalEntry

Verdict: Partial · Read: Full · Write: Partial — Debit/Credit lines split across Desktop JournalDebitLine / JournalCreditLine

QBO field	Support	Notes
PrivateNote	Full	Maps to Desktop Memo when the company file/OSR returns a header Memo on JournalEntry.
Adjustment	Full	Maps to Desktop IsAdjustment.
Line	Partial	JournalEntryLineDetail only. Write splits by PostingType into JournalDebitLine / JournalCreditLine; read interleaves debit then credit lists. Debits must equal credits or create fails UNSUPPORTED_BY_DESKTOP before the Desktop round-trip. Sparse updates cannot modify lines yet (Desktop JE Mod replaces the entire line table when lines are provided — same out-of-scope stance as Invoice lines / issue #55). JournalEntryLineDetail.Entity: only EntityRef is populated on read — Desktop's line-level EntityRef carries no entity-kind flag, so we don't stamp a Type (Vendor/Customer/Employee); a wrong guess is worse than omitting it. Set Type yourself on write if you know it; it's accepted and simply not echoed back.
TotalAmt	Full	Read-only aggregate when present; not independently computed.

Class

Verdict: Full · Read: Full · Write: Full — Hierarchical Class list; SubClass/FullyQualifiedName from Desktop Sublevel/FullName

QBO field	Support	Notes
ParentRef	Full	Becomes a Desktop sub-class; FullName is colon-delimited (e.g. Services:West Coast).

Verdict: Full (read-only) · Read: Full · Write: None — Read/query only — no Desktop write path this release; payroll aggregates out of scope

ExchangeRate

Verdict: Partial · Read: Partial · Write: None — Projected from CurrencyRet.ExchangeRate + AsOfDate; one row per currency that carries a rate; empty when multicurrency is off (statusCode 3250, confirmed live, and 3170 both normalized to [])

QBO field	Support	Notes
SourceCurrencyCode	Full	Desktop CurrencyCode on the same CurrencyRet.
Rate	Full	Desktop ExchangeRate.
AsOfDate	Full	Desktop AsOfDate when present; omitted when Desktop has none.
TargetCurrencyCode	None	UNSUPPORTED_BY_DESKTOP — CurrencyRet has no per-row target; home currency lives on Preferences.CurrencyPrefs.HomeCurrency — never invented here.

Everything else listed as full works unchanged.

Query support

Standard SELECT * FROM ExchangeRate with the shared WHERE / STARTPOSITION / MAXRESULTS subset documented in IDs, SyncToken & sparse updates. Anything outside that subset returns UNSUPPORTED_QUERY.

Not supported

• QBO-style keyed lookup GET /exchangerate?sourcecurrencycode=EUR[&asofdate=...] — UNSUPPORTED_QUERY: Real QBO keys ExchangeRate by sourcecurrencycode/asofdate query params. TenkeyBridge exposes it as a conventional Id-keyed resource (Id = Desktop currency ListID) with SELECT * queries — filter by SourceCurrencyCode client-side.
• Create, update, or delete — UNSUPPORTED_BY_DESKTOP: ExchangeRate is read/query only — projected from CurrencyQuery, not a writable Desktop list.
• Currencies without ExchangeRate on CurrencyRet — UNSUPPORTED_BY_DESKTOP: Projection skips CurrencyRets that do not carry ExchangeRate (home currency rows often omit it).

PaymentMethod

Verdict: Partial · Read: Full · Write: Partial — Create only — Desktop has no PaymentMethodMod; Type coarsens Desktop's fine enum to CREDIT_CARD | NON_CREDIT_CARD

QBO field	Support	Notes

TaxCode

Verdict: Full · Read: Full · Write: Full — Desktop SalesTaxCode list (TAX/NON); Name max 3 chars (fail-loud, never truncated); a plain taxable/non-taxable flag pair, not a rate container

QBO field	Support	Notes
Name	Full	Desktop limits Name to 3 characters. Longer names return 400 — never truncated.
Description	Full	Desktop Desc.
Taxable	Full	Desktop IsTaxable.
SalesTaxRateList	None	UNMAPPED_FIELD — Desktop's US edition (QBD) does not have ItemSalesTaxRef/ItemPurchaseTaxRef on SalesTaxCode — the OSR marks both 'not in QBD' (they exist only for QBCA/QBUK/QBAU). US Desktop SalesTaxCode is just the taxable/non-taxable flag pair; rate association lives on ItemSalesTax items. Read TaxRate for rate values/agency. Never returned on read; writing it faults UNMAPPED_FIELD.

Not supported

• Create or update — UNSUPPORTED_BY_DESKTOP: TaxRate is read-only in QBO; TenkeyBridge matches that parity. Desktop ItemSalesTax items are managed as Items in the company file.
• ItemSalesTaxGroup as TaxRate — UNSUPPORTED_BY_DESKTOP: Sales-tax groups are not projected as TaxRate rows. Group members are themselves ItemSalesTax list items and appear as individual TaxRates via ItemSalesTaxQuery.

Term

Verdict: Partial · Read: Full · Write: Partial — Merged StandardTerms + DateDrivenTerms; Type STANDARD | DATE_DRIVEN dispatches which Desktop list; create-only

QBO field	Support	Notes
Type	Full	STANDARD ⇄ StandardTerms*; DATE_DRIVEN ⇄ DateDrivenTerms*. Fixed at create — the whole entity is create-only, so this can never change via update.

Not supported

• Update any Term field — UNSUPPORTED_BY_DESKTOP: qbXML has no StandardTermsMod or DateDrivenTermsMod — Desktop's OSR only defines Add and Query for both Terms lists. Term write support is create-only.
• Deactivate a Term — UNSUPPORTED_BY_DESKTOP: Deactivation is a Mod-only operation (IsActive via StandardTermsMod/DateDrivenTermsMod), which doesn't exist in qbXML. Impossible via the SDK, not just unimplemented here.

TimeActivity

Verdict: Partial · Read: Full · Write: Partial — Employee time only; Duration compiled from Hours/Minutes or a StartTime/EndTime span

QBO field	Support	Notes
NameOf	Partial	Only "Employee" is accepted (or omitted); "Vendor" is rejected — see Not supported.
EmployeeRef	Full	Required; Desktop EntityRef. Missing value returns 2020.
ItemRef	Full	Desktop ItemServiceRef.
Description	Full	Desktop Notes.
BillableStatus	Partial	Billable, NotBillable, HasBeenBilled; any other value returns 2010. Desktop is stricter than QBO here: "Billable" requires BOTH CustomerRef and ItemRef on the same entry, or QuickBooks rejects the save ("Billable activities must have a customer:job and service item"). Send both, or mark the entry NotBillable. Omitted on create → we emit NotBillable explicitly (QBO's omitted-default); Desktop would otherwise infer Billable from CustomerRef alone. A sparse update that never mentions BillableStatus carries the stored value forward instead — the default only applies to genuinely-absent-on-create.
Hours	Full	Explicit duration input; wins over StartTime/EndTime when both are present.
Minutes	Full	Explicit duration input; wins over StartTime/EndTime when both are present.
StartTime	Full	Alternate duration input paired with EndTime; Desktop only stores the computed Duration, not the span itself.
EndTime	Full	Alternate duration input paired with StartTime; must be after it, or 2010.
BreakHours	Partial	Only valid alongside StartTime/EndTime; supplying it with Hours/Minutes returns 2010.
BreakMinutes	Partial	Only valid alongside StartTime/EndTime; supplying it with Hours/Minutes returns 2010.
HourlyRate	Partial	Accepted and ignored — Desktop time tracking has no pay-rate override at the API level.
CostRate	Partial	Accepted and ignored — Desktop time tracking has no pay-rate override at the API level.
Taxable	Partial	Accepted and ignored — Desktop time tracking has no taxable flag.
CustomField	Partial	Desktop TimeTrackingQueryRq has no OwnerID element (qbXML 13.0), so custom fields are never returned for time entries. Accepted and ignored on write.
CurrencyRef	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.
ExchangeRate	Partial	Accepted and ignored — Desktop manages this itself; multi-currency mapping lands later.
PayrollItemRef	None	UNSUPPORTED_BY_DESKTOP — Desktop PayrollItemWageRef has no QBO Accounting TimeActivity equivalent (QBO Payroll is a separate product).
TxnNumber	None	UNSUPPORTED_BY_DESKTOP — Desktop's internal auto-increment TxnNumber has no QBO equivalent and is not surfaced.

Everything else listed as full works unchanged.

CompanyInfo

Verdict: Full (read-only) · Read: Full · Write: None — Read-only; Id equals the realm ID, no Desktop write path

QBO field	Support	Notes
LegalName	Full	Desktop LegalCompanyName.
CompanyAddr	Full	Desktop Address.
CustomerCommunicationAddr	Full	Desktop CompanyAddressForCustomer — an independent address, not a copy of CompanyAddr; absent if Desktop has none on file.
LegalAddr	Full	Desktop LegalAddress.

Preferences

Verdict: Partial · Read: Partial · Write: None — Read-only singleton (Id=1); honest subset of Desktop PreferencesQuery groups

QBO field	Support	Notes
AccountingInfoPrefs	Partial	ClassTrackingPerTxn/ClassTrackingPerTxnLine ← IsUsingClassTracking (same bool projected to both); TrackDepartments always false (no Desktop Locations).
CurrencyPrefs	Partial	MultiCurrencyEnabled ← IsMultiCurrencyOn; HomeCurrency ← HomeCurrencyRef.
TimeTrackingPrefs	Partial	WorkWeekStartDate ← FirstDayOfWeek only.
TaxPrefs	Partial	UsingSalesTax true when SalesTaxPreferences is present on PreferencesRet; no other TaxPrefs fields.
SalesFormsPrefs	Partial	DefaultShipMethodRef; AllowEstimates/UsingProgressInvoicing from JobsAndEstimatesPreferences. DefaultTerms never populated — Desktop SalesAndCustomersPreferences carries no DefaultTermsRef (qbXML 13.0). IsAutoApplyingPayments has no honest QBO SalesFormsPrefs twin — omitted.
VendorAndPurchasesPrefs	Partial	UsingInventory ← IsUsingInventory only. DaysBillsAreDue / auto-discount have no honest QBO twin.

Budget

Verdict: Planned · Read: None · Write: None — qbXML has no Budget records, but budget figures are readable through BudgetSummaryReportQuery — a read-only Budget synthesized from that report is planned; budget writes stay in the Desktop UI forever.

Desktop has a real qbXML analog, but TenkeyBridge has not shipped this entity yet. Requests return UNSUPPORTED_BY_DESKTOP with a link back here until the implementation lands.

Tracking: #101

Query support

• query — UNSUPPORTED_BY_DESKTOP: Not yet implemented. qbXML cannot enumerate budgets — BudgetSummaryReportQuery requires a FiscalYear — so the planned query path probes a bounded fiscal-year window and synthesizes deterministic Ids. See the tracking issue for the design.
  • Workaround: Until the read path ships, pull the budget-vs-actual reports from Desktop directly (or export), not via the Accounting API.

Not supported

• read — UNSUPPORTED_BY_DESKTOP: Not yet implemented. qbXML has no Budget record API (no BudgetQuery in the qbxmlops130 message set), but BudgetSummaryReportQuery returns budget amounts by account × period (optionally × class or × customer), which is the data QBO's read-only Budget carries. A synthesized read is planned — see the tracking issue.
  • Workaround: Until the read path ships, pull the budget-vs-actual reports from Desktop directly (or export), not via the Accounting API.

  • Workaround: Until the read path ships, pull the budget-vs-actual reports from Desktop directly (or export), not via the Accounting API.
• create — UNSUPPORTED_BY_DESKTOP: Permanent: qbXML has no BudgetAdd. Budget setup stays in the Desktop UI — QBO's own Budget entity is read-only too, so no QBO-compatible client loses anything here.
• update — UNSUPPORTED_BY_DESKTOP: Permanent: qbXML has no BudgetMod. Budget changes stay in the Desktop UI.
• delete — UNSUPPORTED_BY_DESKTOP: Permanent: qbXML has no BudgetDel.

Attachable

Verdict: Never · Read: None · Write: None — QuickBooks Desktop's qbXML API has no attachments interface — the word 'Attachment' does not occur anywhere in the qbxmlops130 message set.

This entity has no honest QuickBooks Desktop equivalent. Every verb returns UNSUPPORTED_BY_DESKTOP — never a silent empty list.

Query support

• query — UNSUPPORTED_BY_DESKTOP: Desktop has no attachments API over qbXML — Attachable queries always fail loud.

Not supported

• read — UNSUPPORTED_BY_DESKTOP: Re-audited 2026-07-29: zero occurrences of any attachment message (no AttachmentAdd/Query/Ref of any kind) across the full qbxmlops130 schema. Desktop's Attached Documents feature is UI-only; files attached in Desktop cannot be listed or fetched through TenkeyBridge.
  • Workaround: Store documents in your own system keyed by the TenkeyBridge entity Id — that is what QBD integrations have always had to do.
• query — UNSUPPORTED_BY_DESKTOP: Desktop has no attachments API over qbXML — Attachable queries always fail loud.
• create — UNSUPPORTED_BY_DESKTOP: Desktop has no attachments API over qbXML — attachments cannot be uploaded through TenkeyBridge.
• update — UNSUPPORTED_BY_DESKTOP: Desktop has no attachments API over qbXML — attachments cannot be modified through TenkeyBridge.
• delete — UNSUPPORTED_BY_DESKTOP: Desktop has no attachments API over qbXML — attachments cannot be deleted through TenkeyBridge.

Department

Verdict: Never · Read: None · Write: None — QBO Departments (locations) have no Desktop equivalent — the only 'Department'/'Location' strings in qbXML are free-text fields on Employee, FixedAsset, and Lead, and Desktop's one real dimensional list (Class) is already exposed faithfully as Class.

This entity has no honest QuickBooks Desktop equivalent. Every verb returns UNSUPPORTED_BY_DESKTOP — never a silent empty list.

Query support

• query — UNSUPPORTED_BY_DESKTOP: qbXML has no Department/Location list to query — confirmed absent from the qbxmlops130 message set.
  • Workaround: Query Class instead if you remap locations client-side; that remapping is your call, TenkeyBridge never reinterprets DepartmentRef silently.

Not supported

• read — UNSUPPORTED_BY_DESKTOP: Re-audited 2026-07-29 against the qbxmlops130 message set: qbXML has no Department or Location list — no Add/Mod/Query message pair exists. The tokens only appear as plain STRTYPE fields (Employee.Department, FixedAsset.Location, Lead.Location), which are annotations, not a queryable list.
  • Workaround: If your integration treats QBO locations as just another dimension, remap DepartmentRef onto Class in your own code — Class is live in TenkeyBridge. We decided against a built-in Department→Class alias, even opt-in: ClassRef already maps to Class, so aliasing would make two QBO fields silently write one Desktop list and collide when a client sends both.
• query — UNSUPPORTED_BY_DESKTOP: qbXML has no Department/Location list to query — confirmed absent from the qbxmlops130 message set.
  • Workaround: Query Class instead if you remap locations client-side; that remapping is your call, TenkeyBridge never reinterprets DepartmentRef silently.
• create — UNSUPPORTED_BY_DESKTOP: Desktop has no Department create. Use Class if you need a dimensional axis on Desktop.
• update — UNSUPPORTED_BY_DESKTOP: Desktop has no Department update.
• delete — UNSUPPORTED_BY_DESKTOP: Desktop has no Department delete.

JournalCode

Verdict: Never · Read: None · Write: None — France-only QBO regulatory feature; not applicable to Desktop — 'JournalCode' occurs nowhere in the qbxmlops130 message set.

This entity has no honest QuickBooks Desktop equivalent. Every verb returns UNSUPPORTED_BY_DESKTOP — never a silent empty list.

Query support

• query — UNSUPPORTED_BY_DESKTOP: JournalCode is a France-locale QBO regulatory concept with no Desktop counterpart.

RecurringTransaction

Verdict: Never · Read: None · Write: None — Desktop's memorized transactions are not exposed by qbXML — there is no message to list, read, create, or execute them.

This entity has no honest QuickBooks Desktop equivalent. Every verb returns UNSUPPORTED_BY_DESKTOP — never a silent empty list.

Query support

• query — UNSUPPORTED_BY_DESKTOP: Memorized transactions cannot be enumerated via qbXML — zero functional API surface.

Not supported

• read — UNSUPPORTED_BY_DESKTOP: Re-audited 2026-07-29: no MemorizedTxn message of any kind exists in the qbxmlops130 message set. The only trace of the concept in the entire schema is a cosmetic 'memorizedTxn' row label in generic report output — a taxonomy tag, not an access path to a memorized transaction's contents or schedule.
  • Workaround: Manage memorized transactions in the Desktop UI. Transactions they generate ARE visible through TenkeyBridge once QuickBooks posts them — they arrive as ordinary invoices/bills/etc.
• query — UNSUPPORTED_BY_DESKTOP: Memorized transactions cannot be enumerated via qbXML — zero functional API surface.
• create — UNSUPPORTED_BY_DESKTOP: Memorized transactions cannot be created via qbXML; manage them in the Desktop UI.
• update — UNSUPPORTED_BY_DESKTOP: Memorized transactions cannot be updated via qbXML; manage them in the Desktop UI.
• delete — UNSUPPORTED_BY_DESKTOP: Memorized transactions cannot be deleted via qbXML; manage them in the Desktop UI.

ReimburseCharge

Verdict: Never · Read: None · Write: None — QBO's billable-charge object has no Desktop record behind it — in qbXML, billability is a status flag (BillableStatus) on the source expense/item/time lines, never a standalone charge you can query.

This entity has no honest QuickBooks Desktop equivalent. Every verb returns UNSUPPORTED_BY_DESKTOP — never a silent empty list.

Query support

• query — UNSUPPORTED_BY_DESKTOP: No standalone billable-charge object exists in qbXML to query; billability is line-level state on source transactions.

Not supported

• read — UNSUPPORTED_BY_DESKTOP: Re-audited 2026-07-29: 'ReimburseCharge' occurs nowhere in the qbxmlops130 message set. Desktop models billability as a BillableStatus enum (Billable / NotBillable / HasBeenBilled) on expense and item lines of purchase transactions and on time entries — there is no separate queryable charge object to project one from.
  • Workaround: Read billable state where Desktop actually keeps it: TimeActivity exposes BillableStatus today, and billable purchase lines live on their source Bill/Purchase transactions.
• query — UNSUPPORTED_BY_DESKTOP: No standalone billable-charge object exists in qbXML to query; billability is line-level state on source transactions.
• create — UNSUPPORTED_BY_DESKTOP: ReimburseCharge is a QBO cloud concept with no Desktop qbXML analog; mark source lines Billable instead.
• update — UNSUPPORTED_BY_DESKTOP: ReimburseCharge is a QBO cloud concept with no Desktop qbXML analog.
• delete — UNSUPPORTED_BY_DESKTOP: ReimburseCharge is a QBO cloud concept with no Desktop qbXML analog.

TaxClassification

Verdict: Never · Read: None · Write: None — Cloud automated-sales-tax concept with no Desktop counterpart — Desktop's tax model is explicit tax items and codes, all of which TenkeyBridge exposes.

This entity has no honest QuickBooks Desktop equivalent. Every verb returns UNSUPPORTED_BY_DESKTOP — never a silent empty list.

Query support

• query — UNSUPPORTED_BY_DESKTOP: TaxClassification is part of QBO's automated sales tax stack; Desktop uses explicit tax items/codes instead.

Not supported

• read — UNSUPPORTED_BY_DESKTOP: Re-audited 2026-07-29: 'TaxClassification' occurs nowhere in the qbxmlops130 message set. Desktop's tax machinery is ItemSalesTax / ItemSalesTaxGroup / SalesTaxCode — explicit records, not AST classification codes — and those ARE available through TenkeyBridge as TaxRate, TaxCode, and TaxAgency.
  • Workaround: Use TaxCode/TaxRate/TaxAgency for Desktop's real tax model instead of AST classifications.
• query — UNSUPPORTED_BY_DESKTOP: TaxClassification is part of QBO's automated sales tax stack; Desktop uses explicit tax items/codes instead.
• create — UNSUPPORTED_BY_DESKTOP: TaxClassification cannot be created on Desktop via qbXML.
• update — UNSUPPORTED_BY_DESKTOP: TaxClassification cannot be updated on Desktop via qbXML.
• delete — UNSUPPORTED_BY_DESKTOP: TaxClassification cannot be deleted on Desktop via qbXML.

TaxService

Verdict: Never · Read: None · Write: None — Cloud AST onboarding operation with no Desktop counterpart — 'TaxService' occurs nowhere in the qbxmlops130 message set.

This entity has no honest QuickBooks Desktop equivalent. Every verb returns UNSUPPORTED_BY_DESKTOP — never a silent empty list.

Query support

• query — UNSUPPORTED_BY_DESKTOP: TaxService is a QBO automated-sales-tax onboarding op with no Desktop API.

Not supported

• read — UNSUPPORTED_BY_DESKTOP: Re-audited 2026-07-29: TaxService is QBO's automated-sales-tax onboarding endpoint; qbXML has zero AST surface. Desktop tax setup happens through ItemSalesTax/SalesTaxCode records, exposed by TenkeyBridge as TaxRate/TaxCode/TaxAgency.
  • Workaround: Create tax rates and codes through TaxRate/TaxCode instead of the AST TaxService flow.
• query — UNSUPPORTED_BY_DESKTOP: TaxService is a QBO automated-sales-tax onboarding op with no Desktop API.
• create — UNSUPPORTED_BY_DESKTOP: TaxService is a QBO automated-sales-tax onboarding op with no Desktop API.

Batch

Verdict: Full · Read: Full · Write: Full — Batch envelope — up to 30 create/update/delete/query operations in one request, executed sequentially with per-item faults.

This is a gateway-level platform endpoint — not an entity. It cannot be queried or CRUD'd through the entity routes.

POST /v3/company/{realmId}/batch

QBO field	Support	Notes
bId	Full	Required and unique per request; echoed verbatim on each BatchItemResponse slot.
operation (create	update	delete)
Query items	Full	Full /query parity: the shared WHERE subset, STARTPOSITION/MAXRESULTS, iterator-backed deep pages.
per-item faults	Full	A failed item returns a Fault slot (with the tkb help block); the rest of the batch still runs.

Everything else listed as full works unchanged.

Not supported

• more than 30 items — BATCH_TOO_MANY_ITEMS: QBO's own per-request cap, cloned. Split into multiple batch calls.
• optionsData (e.g. void) — BATCH_UNSUPPORTED_OPTION: No wired TxnVoid path against Desktop yet — the item faults loud; the rest of the batch runs.
• transactional rollback — UNSUPPORTED_BY_DESKTOP: Batch is not a transaction (QBO's isn't either): items succeed or fault independently; earlier writes are never rolled back by a later failure.
• entity CRUD or /query on Batch itself — UNSUPPORTED_BY_DESKTOP: Batch is a platform endpoint, not an entity — POST /v3/company/{realmId}/batch.

CDC

Verdict: Full (read-only) · Read: Full · Write: None — Change Data Capture — one poll returns changed + deleted records across entities.

This is a gateway-level platform endpoint — not an entity. It cannot be queried or CRUD'd through the entity routes.

GET /v3/company/{realmId}/cdc?entities=Invoice,Customer&changedSince=2026-07-01

QBO field	Support	Notes
entities	Full	Comma-separated QBO entity names. Unsupported names return per-entity Fault slots; live entities in the same request still return data.
changedSince	Full	ISO 8601 timestamp or YYYY-MM-DD, at most 30 days back (QBO's own limit).
deleted-record stubs	Full	status:'Deleted' stubs via Desktop's TxnDeletedQuery/ListDeletedQuery, with TimeDeleted as MetaData.LastUpdatedTime.

Everything else listed as full works unchanged.

Not supported

• changedSince older than 30 days — CDC_INVALID_CHANGED_SINCE: Hard limit, cloned from QBO. Use /query with a MetaData.LastUpdatedTime filter for older data.
• more than 1,000 objects for one entity — CDC_OVERFLOW: Loud per-entity fault, never silent truncation. Page through /query instead.
• deactivated list records reported as deletions — UNSUPPORTED_BY_DESKTOP: Desktop only hard-deletes unused list records. Active:false is a change, not a deletion — it surfaces as a changed record.
• deleted TaxAgency / ExchangeRate / Transfer detection — UNSUPPORTED_BY_DESKTOP: Tax agencies are vendors on Desktop (deletion indistinguishable); exchange rates ride the Currency list; 'Transfer' is not a valid TxnDelType.

Reports

Verdict: Partial · Read: Partial · Write: None — Five QBO-compatible reports translated live from Desktop's report engine.

This is a gateway-level platform endpoint — not an entity. It cannot be queried or CRUD'd through the entity routes.

GET /v3/company/{realmId}/reports/ProfitAndLoss?start_date=2026-01-01&end_date=2026-12-31

QBO field	Support	Notes
ProfitAndLoss / BalanceSheet / TrialBalance	Full	GeneralSummaryReportQueryRq (ProfitAndLossStandard / BalanceSheetStandard / TrialBalance). Values verbatim from Desktop — no recomputation.
AgedReceivables / AgedPayables	Full	AgingReportQueryRq (ARAgingSummary / APAgingSummary). Desktop's file-configured aging buckets come back as columns, honestly.
start_date / end_date / date_macro	Full	ISO dates or QBO date macros (fiscal-relative on both sides, so macros map 1:1). Omit them and you get fiscal year-to-date, matching QBO — Desktop's own bare default is month-to-date, so TenkeyBridge always sends an explicit period.
report_date	Full	The aging reports are as-of a single date. Omit it and QBO's default (today) is used.
accounting_method	Partial	REPORT_UNSUPPORTED_OPTION — Cash/Accrual on the three summary reports. Aging reports reject it — qbXML has no ReportBasis there.
Column titles	Partial	Desktop's own column titles pass through verbatim, so aging buckets read '> 90' where QBO says '91 and over', and a period column reads 'Jan - Dec 26' where QBO says 'Total'. QBO's MetaData.ColKey has no Desktop equivalent and is not invented.

Everything else listed as full works unchanged.

Not supported

• columns / customer / vendor / item / class / department / qzurl / adjusted_gain_loss — REPORT_UNSUPPORTED_OPTION: Column and filter customization is v2. Desktop returns its standard report layout.
• aging_period / num_periods / aging_method — REPORT_UNSUPPORTED_OPTION: Desktop aging buckets are company-file configuration, not request parameters.
• summarize_column_by other than Total — REPORT_UNSUPPORTED_OPTION: qbXML SummarizeColumnsBy exists — clean v2 upgrade path.
• other QBO report names (CashFlow, detail/aging-detail variants, …) — REPORT_UNKNOWN: Planned. The fault lists the five supported reports.
