Bill hours or projects, keep track of what is paid and overdue, and never retype a client’s details again.
There is no account and no server behind this invoice generator. Your business details, clients, products and invoices are stored in your browser's own database (IndexedDB) and never uploaded. The PDF is built on your device. That also means nobody else has a copy — download a backup from Settings → Backup now and then, and keep it with your accounting files.
Enter hours as a decimal, for example 1.5 for an hour and a half, or 0.25 for 15 minutes.
Your data lives in one browser. Download a backup on one computer and restore it on the other. Use a different numbering pattern per device if you invoice from both.
