Easy to use
No setup manuals, no menus to dig through. Big buttons, clear totals — open it up and you already know how to ring up a sale.
Free & open source
A cash register that flaps for non-profits.
Flappies is a minimalist cash register built for volunteer-run shops, markets and fundraisers. Track cash and card, share it across your whole crew, and keep every flappie (that’s Dutch for dollar bill) accounted for.
Self-host it yourself for free, or let us run it for you — hosting and support come at a cost to cover our infrastructure and team.
Simple by design
Built for a whole crew of volunteers
Hand it to whoever’s on shift. No accounts to remember, no training needed — if they can use a phone, they can run the register.
