billsend is a free, privacy-first invoice creator that runs entirely in the browser. No accounts, no servers, no tracking. Your data never leaves your device. Built for freelancers and small businesses who need professional invoices without the complexity.
Invoices are fully customisable with flexible templates, layout controls, and PDF export. All data is stored locally in the browser using IndexedDB via Dexie. It isn’t a demo: I built it for my own freelance invoicing and use it with every client.
