Show HN: PlainInvoice – A minimal invoicing tool for freelancers and small teams
plaininvoice.comHi HN, I'm a freelance developer, and like many others, I used to manage invoices through clunky spreadsheets, reused templates, and endless email threads with my accountant.
To simplify that, I built PlainInvoice.com — a minimal invoicing tool designed for freelancers and small teams. It's clean, fast, and doesn't require sign-up to start.
Some features:
Generate invoices instantly (no login needed)
Save clients, track total billed and actual received (with multi-currency support)
Upload attachments (like receipts or contracts)
Add teammates or accountants with viewer-only access
Works well for solo folks who just want to stay organized without bloat
Here’s a short walkthrough video: https://youtu.be/b3ywvs-8nYM
It’s free to use for now. I built it for myself but figured it might help others too. Would love your feedback or suggestions! I'm actually digging into the topic of protecting freelancers by helping them handle client relationships, including backend stuff like invoicing. If you're open to it, I'd love to learn more about frustrating backend work that you've built fixes to (like plaininvoice.com) or others that you haven't but would really want to. Have you shared PlainInvoice.com with others or gotten feedback on any usage?
