OSPOS is a free, open-source point-of-sale app that turns your iPhone into a full POS system. Accept cash. Accept cards. No monthly fees. No contracts.
Every other POS charges you monthly, plus per-transaction fees, plus hardware costs, plus add-on fees. We charge nothing for cash and 1% for cards. That's it.
Cash-only POS with menu builder, order tracking, daily summaries, and CSV export. No account needed. No internet required. Works completely offline. Zero dollars, zero catches.
Accept tap, chip, and swipe payments via Stripe. We charge 1% per card transaction on top of Stripe's standard rate — that's it. No monthly fees, no minimums, no hidden charges.
Download, build your menu, start selling. Card payments take five minutes to enable with Stripe. No hardware required — Tap to Pay on iPhone works right out of the box.
All data stored locally on your device. We never see your sales data unless you opt into cloud sync. No card numbers ever touch our servers. Open source — audit the code yourself.
Add items with photos, categories, and custom pricing. Rearrange your grid with a tap.
Accept contactless cards with just your iPhone. No reader needed. Uses Apple's built-in NFC.
Daily summaries, date-range reports, and CSV export. Know exactly how your business is doing.
