TenkeyBridgeThe QuickBooks Online-compatible API for QuickBooks Desktop & Enterprise.

Point your QuickBooks Online code at QuickBooks Desktop. Most of it just works — and we tell you exactly what doesn't.

Base-URL swap

Same OAuth 2.0 flow, same paths, same JSON entities. Change one constant and your existing QuickBooks Online integration talks to Desktop and Enterprise.

Honest compatibility contract

Every entity, every field, every gap is documented — generated straight from the same data that drives the translation engine, so the docs can't drift from reality.

Fail-loud errors

Anything Desktop genuinely can't do returns a stable, versioned QBO-style Fault you can branch on. No silent surprises.

Status: early development

TenkeyBridge is contract-first — the hosted gateway isn't live yet. This site documents the compatibility contract we're building and testing against today.
