Restaurant Payments: A Complete Guide for Restaurant Operators
Why the payment system matters
Every sale in your restaurant goes through a payment system, so a bad one costs you every single day. You pay more in fees, checkout is slower, and someone ends up matching card totals against the till at close. A good one you barely notice. The customer taps, the payment goes through, and the numbers turn up in your reports without anyone typing them in.
This guide is for restaurants in the UK and Ireland.
Types of restaurant payment systems
Standalone card terminals
A card machine that isn't connected to your POS. A staff member reads the total off the till and types it into the terminal. That's where keying errors come from. Nothing reconciles automatically either, so at the end of the day someone has to check the terminal totals against the POS by hand.
Plenty of small independents still use these. The extra admin, plus the odd £45 that got keyed in as £54, adds up over a year.
POS-integrated payments
Here the terminal connects directly to your restaurant POS system. The POS sends the bill total to the terminal, the customer pays, and the POS record updates straight away. Nobody types an amount.
If you're running a proper tech setup, this is what you want. No keying errors, faster checkout, and end-of-day reports that are right without anyone fixing them.
Online payments
With restaurant online ordering, the payment gateway is built into the ordering platform. Customers pay by card, Apple Pay or Google Pay at checkout, and the order lands in your kitchen already paid.
Pay at table
The customer scans a QR code, or uses a device at the table, and pays without waiting for someone to bring the bill. Tables turn faster and staff spend less time walking card machines around the floor.
Card processing fees in UK restaurants
Card fees usually have three parts:
| Fee type | What it covers |
|---|---|
| Interchange fee | Set by the card scheme (Visa, Mastercard). Non-negotiable. |
| Scheme fee | Charged by the card network |
| Acquirer margin | Your payment processor's charge |
All in, UK restaurants usually pay somewhere between 0.5% and 2% of transaction value. Where you land depends on the card type, how much you process and what you agreed with your acquirer.
Also check the contract for:
- minimum monthly fees, which hurt if your volumes are low
- rental charges on card terminals
- PCI compliance fees
- chargeback fees when a customer disputes a payment
What to look for in a restaurant payment system
Start with POS integration. Your payments and your POS should be the same system, or at least directly connected. Manual entry is where the mistakes creep in.
It helps a lot if one platform handles both online and in-person payments. Then there's one set of reports and nothing to reconcile between two systems.
Speed matters more than people expect. In a Friday rush, a contactless payment that confirms in under three seconds keeps the queue moving. A slow terminal holds everyone up at the worst possible moment.
Ask about reliability. If payments go down, you lose sales. Check the provider's uptime record and find out what happens when the connection drops. Can you still take cash, or does everything stop?
Reporting should be simple. You want daily, weekly and monthly figures for transactions, tips, refunds and voids without building a spreadsheet yourself.
Common payment problems for restaurants
Split bills are the classic one. Without POS integration, staff work out each person's share and key it in separately. An integrated system does the maths for you.
Tips need proper handling, especially in sit-down restaurants where gratuities make up a real chunk of staff pay. You need clear tip entry on the terminal and tip totals in the reports.
Refunds should be done from the POS. If you have to ring a support line to refund a customer, that's a bad sign. Check how refunds work before you sign anything.
Then there's closing up. With separate payment and POS systems, someone compares two sets of figures every night. With integration, that job goes away.
How Flipdish handles restaurant payments
Flipdish Payments is part of the Flipdish restaurant technology platform. Orders placed through Flipdish websites, apps and kiosks all go through Flipdish Payments, so every channel uses the same system.
In practice that means:
- online and kiosk orders reach the kitchen already paid
- there's nothing to reconcile between a separate payment processor and the ordering platform
- transaction data goes into the same reports as your in-person sales
- customers can pay by card, Apple Pay or Google Pay on any channel
Flipdish also has its own POS and POS hardware, so in-person and online payments can run through one platform.
Card machines for restaurants
The best card machines for restaurants connect directly to your POS. A standalone device puts you back to typing in totals.
Before you pick one:
- check it works with your POS
- find out whether you're buying it or renting it, because rental is a monthly cost that never stops
- make sure it takes contactless, chip and PIN, and mobile wallets
- confirm the provider has support in the UK and Ireland, and ask how quickly they actually respond
Getting started
For most restaurants, do it in this order:
- Pick a POS system that has payment processing built in, or a direct integration with a payment provider.
- Make sure online ordering payments run through the same platform, or one that works with it.
- Check the card terminal works with your POS before you sign an equipment contract.
- Get every fee in writing, including equipment, processing and compliance, before you commit.
