Journal entry with rule + pack version
Luca categorizes a card charge and posts the journal. The entry stores the rule name, rule-pack version, and whether AI proposed or approved it.
The AI-operated back office
Luca runs your books, invoices, bills, payroll, and cap table on one ledger — and every period close comes with a certificate anyone can verify.
What Luca does
Real actions across the business
Each example is a different module. Luca takes the action, and the ledger records what happened.
Cap table update + equity subledger post
Luca records a share issuance to a holder. The equity subledger posts in the same pass, so ownership and the books stay aligned.
Issue shares on the cap table
Cap table →AR invoice or AP payment on the ledger
Luca creates an invoice from the catalog, or pays a vendor bill against AP. Revenue or payable hits the ledger with the line snapshots intact.
Raise an invoice or pay a bill
AR →Sealed period + close certificate
The close checklist completes, the period seals, and a close certificate publishes with a link anyone can verify.
Seal the period close
Open books →Proof, on live books
Live books, posting now
These are real books — ours and our customers’ — posting live. We publish our own closes, sealed and verifiable.

The finance stack, exposed as tools
TripleBooks is an agentic finance stack by design. Every platform action is a tool an external agent can call, with the same permissions and ledger posting as the in-app assistant.
Every action is a tool
Platform actions ship as MCP tools. Luca and any other agent call the same surface the product uses internally.
Any agent can drive it
Claude, Cursor, ChatGPT, or your own automation. Connect through MCP and operate inside your tenant with RBAC intact.
Reach across the business
Accounting and close, treasury, invoicing and AR, bills and AP, CRM, cap table, governance, HR payroll, and documents.
