Zanii Fleet · Accounting brain

One correct set
of books.
Every bot plugs in.

The multi-tenant double-entry engine behind the fleet. Ingest every payment once, keep a balanced ledger per client, and expose it over an API so any bot in the fleet can track, chase and file, without ever touching accounting logic.

01Bank feed

Connect the bank. Post itself.

Pull transactions straight from the bank over an API. Every line is categorised, matched, and posted as a balanced entry, automatically. Nothing is entered twice.

  • Open-banking pull (UAE via Lean)
  • Idempotent: a transaction posts once, ever
  • Unsure lines wait in Suspense, never guessed
Bank feed
02AI categorisation

A bookkeeper that never sleeps.

Claude reads each transaction and maps it to the right account with a confidence score. Above the line it posts; below it, a human decides. The AI proposes. The ledger disposes.

  • Confidence-gated, never auto-posts a guess
  • Learns your chart of accounts
  • No LLM anywhere in the money math
AI categorisation
03Double-entry core

Books that can’t go out of balance.

Every event is a balanced journal entry, enforced by the database itself, not hopeful application code. One tenant, one book, isolated at the row level. Corrections are reversals, never edits.

  • Balance enforced by a DB constraint
  • Row-level isolation per client
  • Immutable, append-only ledger
Double-entry core
