About
Self-hosted invoicing you own outright - no monthly fee, no cut of what you bill, no invoice cap. Estimates convert to invoices in one click, every document renders to a branded PDF, and clients open a public link without an account. Record part-payments and see what you are owed by client and by age.
Recurring invoices draft each cycle for you to review; a unique period stamp means the same month can never draft twice. Nothing is emailed automatically - every client email is a button you press, sent through your own SMTP, each attempt logged. Version 3.1 adds emailed invoices and reminders plus an .ics feed of due dates, all shipped switched off.
Also included: REST API with revocable keys, webhooks, an MCP endpoint for AI assistants, 2FA, OIDC sign-in, scheduled backups, audit log, dark mode. Plain PHP 8 + MySQL or SQLite, no framework, no build step. It never phones home.
A live demo runs on the product page - it opens signed in, with no signup and no password.
