Square made card payments boring, in the best possible sense. The till works, the reader works, the money lands, and a new member of staff can be taking payments within an hour of starting. Square for Restaurants extends that same plainness into menus, order routing, inventory and kitchen flow. For a lot of restaurants that simplicity is exactly why they chose it, and it was a good reason.
Resk (formerly Elyx) is an AI operator platform for restaurants, built in Ireland, and this comparison is not about the till. Square runs the till well. The comparison is about what happens around the till: the call that rang out while the queue was being served, the payment link that failed after the guest had left, the regular who has quietly stopped coming in. The till records the day faithfully. It does not chase the parts of the day that went wrong.
What Square is genuinely good at
Payments and POS simplicity, honestly delivered. The hardware is clean, checkout is fast, menu management is straightforward, and orders route to the kitchen without drama. Inventory and reporting tools are there when you want them. If your main problem is the till itself, or payments, menu management or order routing, Square is a strong fit. If you need a POS, kitchen display or payment setup as the core system, it is a fair place to land.
The till records; nobody chases
A till is a system of record. The trouble is that a restaurant's worst leaks are not records. They are absences.
Start with the payment that failed after the moment had passed. A deposit link for a Friday party bounces, or expires unopened. The transaction that never happened does not appear in any report, because reports are made of things that happened. Square takes and records payments well; the chase around failed links, deposits and guests gone quiet is not its core loop. Someone on your team has to notice the silence. Resk is built to notice it. The failed or unpaid link gets spotted, the reminder is sent or prepared for your approval, and the recovery status comes back to the Operator so you know whether the money actually moved.
Then the call during the lunch queue. The phone rings while three people are waiting at the counter, and the person on the till has a choice: serve the queue or take the booking. Square is not built to answer restaurant calls, and does not claim to be. Resk's voice agent answers, remembers the guest, checks your rules and moves the booking, order or deposit along while your staff keep the queue moving.
Bookings more broadly sit outside Square's world. It is not a booking engine built around calls, waitlists, deposits and no-show recovery, so if tables and deposits matter to your model, that work lives somewhere else. Resk connects voice, web bookings, deposits, reminders, waitlists and guest history in one path.
And then the margin question the reports leave with you. Square's inventory and menu tools genuinely help here, so this is a partial gap rather than a hole. The reports can show you movement. What still needs a human is the interpretation: which supplier increase actually hurts, which dish to reprice, when to change the order. A live example: Ireland's VAT on food and catering services dropped from 13.5% to 9% on 1 July 2026 under Budget 2026. Welcome news, but somebody still has to decide what it means for your menu prices, item by item, and the till will not volunteer an opinion. Resk reads POS sales, stock, recipes, invoices and supplier notes together, then drafts the price, menu or order action and waits for your approval.
The honest comparison
| Capability | Square | Resk |
|---|---|---|
| POS, payments and hardware | Strong | Covered, connected to the owner action layer |
| Voice agent for calls | Not built for this | Answers, remembers guests, moves the next step |
| Payment recovery after the transaction | Partial; records well, chasing is manual | Finds unpaid moments and runs the chase |
| Bookings, deposits and no-show work | Not covered | One booking path across voice, web and deposits |
| One daily owner brief | Not covered | Turns the day into ready-to-approve work |
Choose Square if
- Your main problem is the till, payments, menu management or order routing.
- You need a POS, kitchen display or payment setup as the core system.
- Someone already checks every payment issue, discount and customer follow-up after service.
That third line is the honest test. Some restaurants have a manager who reads the till exceptions every night and acts on them the next morning. If that is you, the leak Resk hunts may already be plugged.
Choose Resk if
- The POS records what happened, but nobody owns what needs doing next.
- Failed payments, refunds, discounts and quiet customers need follow-up that keeps slipping.
- You want calls, payments and till exceptions turned into a short daily list.
Resk can provide the POS, hardware and payments too, so the till and the follow-up live in one place rather than two. And the usual honesty applies: Resk does not cut your rent or your energy bill. Its claim is the leak: missed demand, unpaid money and exceptions nobody chased, gathered into one brief each morning.
What to measure in a 30-day trial
Write the questions down before day one:
- Which till and payment exceptions should have been chased, and were they?
- Which customer follow-ups were handled without you nudging anyone?
- Can you see the day's money risks in minutes rather than an evening of reports?
If after 30 days the exceptions list comes back empty, fair play: your operation is tighter than most, and you have proven it cheaply.
