Seamless + Square: keep your Square payments, upgrade the till

If you take payments with Square but your till needs more, Seamless works with your Square Terminal. Pair it once and the till pushes every payment to the terminal automatically. We should say up front: Square is a partner, and pays us a share when venues process through this integration.

Keep your Square rates, change only the till: tabs, seat numbers, coursing, kitchen printing and screens, delivery integration, recipe based stock.

No contract

Your Square rates stay yours

How the Square integration works

Connected from your own Square account, in minutes

1

Step 1

Connect your Square account

Link your existing Square account to Seamless from the backoffice. You approve the connection with Square directly, and your merchant account, rates and settlement stay where they are.

2

Step 2

Pick a location, pair the Terminal

Choose which Square location the payments book against, then pair each till to a Square Terminal with a six character device code. On the Terminal, choose Sign in with a device code and type it in. The code lasts about five minutes.

3

Step 3

Take integrated payments

Totals push from the till to the Terminal automatically. Refunds and split bills run from the till, and every payment lands on the order it belongs to.

Why integrate?

What the Square integration actually does

Seamless is the till layer. Square carries on doing the payments. You get everything on all features, including the table service, coursing and kitchen display work that venues outgrow simpler tills for. Run it on an iPad, an Android device, or an all-in-one unit from our shop, alongside the Square Terminal you already have.

What stays with Square

  • Your Square account, your rates and your settlement

  • Square processes the payment and pays it into your bank, exactly as today

  • The Square dashboard still shows the money side

  • Your existing Square Terminal, now paired to Seamless POS

What the till gains

  • Refunds from the till, whole bill or single item, back to the original card

  • Split bills: part-pay on the Terminal and settle the rest any way you like

  • The till re-checks an interrupted payment instead of charging it again

  • Tabs, seat numbers, coursing, kitchen printing, kitchen screens and stock

Who this suits

Venues that like Square's payments but have outgrown Square's till

Table service that needs seats and courses, kitchens that need routing or screens, operators who want delivery platforms in the same system. If Square's own POS still does everything you need, keep it: it is genuinely good for simple counter service, and we say so in our honest comparison.

Pricing

No contracts. Cancel anytime.

Two plans, both month-to-month, and the Square integration is included on both. Square's payment rates are between you and Square, and do not change when you add Seamless. The £0/month Seamless plan comes via our payments partner Teya, not Square: keeping Square costs £24/month and leaves everything else exactly as you have it. Both are fair choices, and the pricing page lays them side by side.

Who's behind Seamless

Built by the team behind IntelligentPos

Our founders built and sold IntelligentPos, one of the UK's leading iPad EPOS systems, to iZettle (now PayPal / Zettle) in 2016. Seamless is what we'd build now: stripped back, on iPad and Android, with direct integrations to the payment partners operators actually use.
