OSPOS

Now on iPad. Pair it with your iPhone and you have a two-piece register: ring the order on the iPad, the customer watches their total and taps their own card.

Turn the iPhone and iPad you already own into a full cash register. Cash sales are free forever. For cards, connect your own Stripe account and OSPOS adds 1% on top of Stripe's rate — no monthly fee, no contract, no card reader to buy.

NEW — YOUR IPAD IS NOW THE REGISTER OSPOS runs on iPad, laid out for a counter: your categories down one side, the menu grid in the middle, the running order on the right. Everything is where your thumb already is.

NEW — TWO DEVICES, ONE REGISTER Pair an iPad and an iPhone and OSPOS splits the register in two. Ring the order on the iPad; the iPhone faces the customer, mirrors the cart line by line as you build it, and takes the tap. No extra hardware, no extra fee.

• The customer watches their order total as it's rung, then taps their own card
• Pair once with a four-digit code; the two devices reconnect on their own
• Either device can be the register — swap roles whenever it suits the counter
• Every message between the two is signed, so nothing nearby can read your cart

TAKE CARDS WITH NO CARD READER Tap to Pay on iPhone accepts contactless cards, Apple Pay, and other digital wallets directly on your iPhone. Nothing to plug in, nothing to charge, nothing to lose behind the counter.

BUILT FOR REAL COUNTERS

• Modifier groups — size, milk, extras, with required and optional choices
• Mark an item sold out for the day without deleting it
• Discounts and comps on the whole order, with the tax handled correctly
• Per-item tax, so packaged retail and prepared food can live on one menu
• Edit a line after it's rung, straight from the cart

WORKS WHEN THE INTERNET DOESN'T Cash sales need no connection at all. Card payments queue and settle themselves when you're back online. The register does not stop because the Wi-Fi did.

KNOW YOUR DAY Today's takings, transaction count, average sale, and the cash/card split. On iPad you also get an hourly chart of when the money actually came in, and the day's transactions beside it. Export any date range to CSV.

RECEIPTS Email receipts, or none at all. No customer is ever forced to hand over an address to buy a coffee.

PRICING Cash mode is free forever and needs no account, no card, and no trial.

For card payments you connect your own Stripe account and keep it. You pay Stripe their normal in-person rate, and OSPOS adds 1% on top. That 1% is the whole of what OSPOS costs.

No monthly fee. No minimum. No contract. No hardware to buy or rent. If you stop using OSPOS you keep your Stripe account and your customer history.

OPEN SOURCE OSPOS is open source under the MIT licence. You can read exactly what the app does with your money and your customers' data, because the code is public.

Requires iOS 16.0 or later. Tap to Pay on iPhone requires iPhone XS or later. Card payments are currently available to merchants in the United States.
