Make an invoice. Download the PDF.

A free invoice generator with no signup. The PDF is built in this tab, so your rates, your client's name and the amount never reach a server.

How this works

Fill in who the invoice is from, who it is for, and what you did. The totals update as you type, and the tax line only appears on the PDF when you set a rate. Press download and you get a one-page PDF you can attach to an email.

Is it really free?

Yes, with no signup and no limit on how many you make. Prooflock is a paid product for the part that comes after: handing over the finished files without losing the leverage to get paid. Every PDF carries one small line at the bottom saying where it came from.

Where does my data go?

Nowhere. The PDF is assembled by code running in this tab, and nothing you type is sent to us or stored. Closing the tab loses the draft, so download before you go.
