Billr

I kept noticing the same problem around me — self-employed people, tradespeople, freelancers — smart, hardworking people who were either paying €20+ a month for invoicing software they used once a week, or sending invoices from a Word doc and chasing payments over WhatsApp.

Neither option made sense. The software was overkill. The manual approach was costing them time and making them look unprofessional.

I'm a graphic designer and I build automation tools for myself. I knew the problem was solvable in a weekend. So I built Billr — a single HTML file that works like a proper invoicing app, runs entirely in your browser, saves your data locally, and costs €27 once. No subscription. No login. No cloud. No monthly fee creeping up on you.

It exists because most invoicing software wasn't built for the self-employed person who has 8 clients, sends 12 invoices a month, and just wants to get paid without thinking about it.

Billr is that tool. Simple, calm, and permanently yours after one purchase.
