Books that balance.
Books you own.
Real double-entry bookkeeping for freelancers and sole proprietors who file a Schedule C. Import your history from QuickBooks or Wave in minutes, keep your data forever, and pay $39 a year — not $30 a month. A real REST API sits underneath when you want it.
$39 a year — not per month, not per seat. Or $99 once, forever →
Rented software on one side. A shoebox of receipts on the other.
There's a room nobody built for the freelancer: real double-entry books you own outright, your history imported in minutes, priced for one person — not a monthly rent, not a spreadsheet that never ties out. Finappses lives there.
Your books, programmable.
Not a developer? Skip this — the whole app runs by clicking, and you'll never touch a line of code. But if you'd rather automate your books: every account, entry, and report is a resource behind a clean REST API. UUID-keyed end to end, RFC 7807 errors, predictable envelopes. Post a journal entry from a webhook. Pull a P&L into your own dashboard. Reconcile from a cron job.
- UUID resources everywhere. No leaky auto-increment IDs — every record is a stable string you can reference safely.
- RFC 7807 problem responses. Errors you can branch on, not HTML you have to scrape.
- The ledger enforces itself. The API refuses an unbalanced entry — your integrations can't corrupt the books.
- Self-hosted, MCP-ready. Point an agent at your own instance and let it read reports or draft entries.
