The immutable ledger for money that has to be explained.
An AI agent watches every account, categorizes every dollar to the regulator's rules, drafts filings for your approval, and publishes a live public transparency feed. Every entry cryptographically anchored. Every filing publicly verifiable.
An agent that acts — not software you operate.
Accounting software is a tool you run yourself. openbooks.fyi runs the back office: it watches, prepares, and warns — then acts the moment an officer approves.
Always on every account
Connected read-only, the agent categorizes every transaction as it lands and keeps every filing period current. No month-end scramble, no reconstruction at the deadline.
Drafts the filing
Your next regulatory report — CSC, 990, LM-2, an owner statement, a trust reconciliation — is prepared and waiting. An officer approves; nothing is filed or published without a human yes.
Before it becomes a finding
A deadline, an unclassified dollar, a trust shortfall, an entry that breaks the chain. You hear about it with runway to act, not as an audit finding after the fact.
Built for money the public gets to check.
Five verticals, one substrate. Each one categorized to its own rule set, filed on its own schedule, and anchored in the same verifiable ledger.
Campaigns
Every contribution and expenditure categorized to the Campaign Spending Commission rules, filings drafted for your treasurer to approve.
Explore Campaigns →HOAs
Association dues, reserves, and vendor payments tracked to the condominium statute, owner-ready financials published on a schedule.
Explore HOAs →Nonprofits
Revenue and expense classified to the functional categories the Form 990 needs, filings drafted for your board to approve.

Receipts and disbursements categorized to the schedules the LM-2 requires, the annual report drafted for officer approval.
