AccountingKit

AccountingKit is a durable accounting automation platform for B2B software. It starts with a deep Xero implementation: customer-owned OAuth apps, live and cached accounting reads, lossless writes, and multi-step workflows that resume safely after retries and restarts.

What is available

• Test and live environments with independently scoped API keys and connections.
• Customer-owned Xero apps for paid production contracts; hosted OAuth for trials.
• Encrypted OAuth credentials, rotating tokens, per-app webhooks, and explicit tenant selection.
• Cached list reads, live point reads, and normalized resource writes.
• Idempotent multi-step automations with retries, leases, and dead-letter state.
• Signed outbound webhooks and verified inbound Xero webhooks.
• Contract-defined connection limits and invoice-ready usage metering.
• A developer console for keys, connections, operations, contract terms, and usage.

Start here

Register a Xero app and create a test connection by following the quickstart. Start with an automation recipe, read concepts for the tenancy model, inspect the integration catalog, then use the API reference for individual primitives.

Current product boundary

Xero is the only publicly available provider in the first release. QuickBooks Online appears as coming_soon; FreshBooks, Wave, and Sage Intacct have executable foundations but are not registered in the public API. The contract stays provider-neutral, while explicit provider actions preserve capabilities that cannot be normalized honestly.
