What changes

In week one. Not year one.

01

The whole accounts team works one ledger, so month-end starts from numbers that already agree.

02

GST and TDS checks run inside every transaction flow, not as a quarter-end scramble.

03

Live cash position and AR/AP aging sit in one view, and per-user accounting fees end.

And the QuickBooks renewal stops being a line item — the replacement is an asset you own. Run your numbers →

Headless by contract

Every screen here also works without the screen.

OwnBooks implements the Own360 headless spec: a standard /api/v1 surface with OpenAPI, cursor pagination, idempotent writes, and entity.changed events — drivable from its own CLI, any HTTP client, MCP tools generated straight from its OpenAPI, and the OwnAgents runtime.

$ ownbooks entities            # 11 entities
$ ownbooks invoice list --limit 20
$ ownbooks invoice create --data '{…}'
$ ownbooks domain send_invoice

The generated OwnBooks CLI — every entity and domain op, OwnAuth-authenticated, idempotent by default.
