- Works with Claude, ChatGPT, and Claude Code — any MCP client
- Scoped to the role of the person who connected it — never more

Add this URL as a custom connector in Claude or ChatGPT — access stays scoped to your role, and every action lands on the audit trail.
Three steps to books that stay ready.
No migration project, no consultant, no month-long setup.
Set up your books
Add your company and chart of accounts, invite your team, and connect Claude or ChatGPT — each with the right role.
Run the daily money work
Invoice customers, capture bills, and review bank activity. Your assistant can help, but you stay in control of what posts.
Close with live numbers
P&L, Balance Sheet, Trial Balance, and the audit trail update from the same posted entries — no second set of numbers to reconcile.
Real controls, not a checkbox.
Exactly what protects your books when a human or an AI touches them — actual product behavior, visible in your own Settings → Audit Logs.
Role-based access, enforced live
Four roles: admin, accountant, member, viewer. Every action — human or AI — is checked against your current role, every request. Change someone's role, or disconnect an assistant, and it applies to their very next action, not eventually.
Every change is logged, including the AI's
Settings → Audit Logs records every change to your books. Actions taken by a connected AI assistant are tagged distinctly, so you always know whether a human or an assistant made a change.
Revocable, always
Disconnect a connector and its access is cut off immediately — every active session stops working, and it must go through the full connection flow again. Nothing in your books changes.
Consent, every time
Connecting an AI assistant always shows an explicit approval screen naming exactly what it's asking for and which company. Never silent, even on your second connection.
The ledger can't be silently rewritten
Debits and credits must balance before anything is written — the server posting chokepoint refuses an unbalanced entry. Corrections happen by voiding and reversing, never by editing history.
What we don't claim yet
We haven't pursued SOC 2 or ISO 27001 certification. What's here is what you can see directly in the product today — not a badge, the actual mechanics.
