- Full bookkeeping surface over REST: chart of accounts, journals, reports, close
- POST a transaction, get a balanced journal entry back in the same response
- Trial balance, P&L, balance sheet, and cash-flow statements as queryable APIs
- Multi-tenant by API key — one auth token per agent, one books view per call
- Webhooks fire on every posted entry so downstream agents react in real time
- Idempotency keys prevent double-posting on retry or concurrent agent calls
- OpenAPI spec generated from the same source the runtime serves
AI Bookkeeping API: Double-Entry Bookkeeping as a REST Endpoint
QuickBooks was built for humans at a keyboard. AI agents are not at a keyboard. The AI bookkeeping API exposes the entire bookkeeping surface — chart of accounts, journal entries, trial balance, financial statements, period close — as REST endpoints an agent can call from any runtime. No UI required, no human required, and no monthly reconciliation window between "agent paid" and "books updated."
