A free invoice generator for freelancers who work with Claude. You talk; it asks for exactly what it needs, one question at a time; you get back a clean, immutable invoice with a link to send your client. Ahead of the work, partial, or after — your agreement, your call.
Start free with Google → See it working firstAn issued invoice is immutable. Fixing a mistake is a void with a reason and a fresh invoice — the number stays burned, the history stays honest. Exactly what your accountant wishes you did.
The seller block — your name, address, payment instructions — freezes onto each invoice at issue. Change banks next year; last year's invoices still say what they said.
It never invents an amount, a rate, or a date — it asks you. And everything it does lands in an audit trail you can read, refusals included.
Payments are recorded as they arrive — unapplied money is a real, visible state, never silently matched. Outstanding shows the truth, oldest first.
You get your own private space for invoices. Nothing to install.

That's genuinely all. The agent knows this space's rules and guides you from there — company details, client, the work, every number shown before anything is issued. Prefer forms? The same books are in your browser, and each side picks up what the other did.
