About Slipbook

Slipbook is a free tool for freelancers and small businesses. It makes invoices, quotes, and receipts, and it keeps a record of them, so you can see who has paid.

The idea comes from the duplicate receipt book that shops and tradespeople have used for generations. You hand over the top copy, and the numbered copy stays in your book. Free invoice tools often stop at the top copy. Slipbook keeps the book too.

How it works

Everything runs in your browser. Your documents, clients, and prices are saved on your device, not on our servers, and there is no account to create. It keeps working without a connection after your first visit.

How it stays free

The site costs very little to run, because your records never touch a server of ours. Public pages like this one may show ads in future. The screens that hold your records never will.
