Tools that get freelancers paid

About

I make small, offline-first tools for freelancers - contracts, invoices, and the awkward emails that get an overdue invoice paid. No subscriptions, no accounts, nothing that stops working when you stop paying.

Offline Invoice - An entire invoice generator in one 57KB HTML file

One HTML file, 57KB. No build step, no dependencies, no CDN, no backend. Save it to your desktop, turn off your wifi, and it keeps working — your data stays in your own browser because there is nowhere to sync it to. Line items, 22 currencies, tax, discounts, deposits, saved clients, and print-to-PDF at A4. Add #selftest to the URL and it runs 26 assertions on the money and date maths in front of you. Free and unlicensed, source on GitHub.
