FillFrog POS

A feature-packed POS, built by retailers.

We built FillFrog POS because the tools we needed didn't exist — or cost too much. So we made one that's elegant, fast, and completely free to use. You'll never pay a monthly fee to ring up a customer.

✓
Inventory & volume pricing. Track stock in real-time. Sell by unit or by volume for fuel and bulk goods.
✓
Z-Reports & audit logging. Daily reports, printable receipts, and a full searchable log of every event.
✓
Cashier PINs & team permissions. Every sale is attributed. Every action is tracked.
✓
Cash & card payments. Set a processing fee per product — your customers cover the card cost, not you.
✓
Works on any device. No app installs, no hardware locks. Just open a browser and sell.
