Not on the list? There are dozens more
These 8 are the systems we see most often in UK and European independents, but Zapier's directory lists dozens of point of sale and booking platforms, and the same two-step pattern works for any of them. If your system has a Zapier app with a sale, order, or customer trigger, it can stamp Leal cards. Among the others worth knowing: Odoo for businesses running POS inside a wider ERP, Biyo POS for restaurants and retail, and Final POS for inventory-led shops.
Search your POS name in Zapier to check, then follow any guide above as a template. Stuck, or your till has no Zapier app at all? Leal still works alongside any system with QR code stamping. Tell us what you run and we will point you to the quickest setup.
How loyalty integration actually works
Every system on this list follows the same pattern. A sale on your till fires its Zapier trigger, Leal's Find customer action matches the buyer by email or phone, and Leal's Add stamps action moves their digital card forward in Apple Wallet or Google Wallet. You build that flow once in about 15 minutes with no code. And if your till is not on this list, Leal still works alongside it, with customers scanning a QR code and staff stamping in seconds.
Zapier route
POS sale triggers a Zap, Leal finds the customer and adds a stamp. No code, about 15 minutes.
Alongside route
Customers scan a QR code, staff stamp with the Leal scanner. Works with any till, live in minutes.
API route
Open POS APIs plus the Leal API allow fully automated stamping. Talk to us and we will help you scope it.
Frequently asked questions
What is the most popular POS system in the UK?
Square, SumUp, and Zettle by PayPal lead among small UK businesses thanks to low-cost hardware and flat-rate pricing, while Epos Now is the most recognised UK-founded EPOS brand. Larger hospitality groups typically run Zonal, ICRTouch, or Tevalis.
Which POS systems work with Zapier?
Square, Epos Now, Shopify POS, Lightspeed Retail X-Series, Loyverse, Flipdish, Erply, and PHP Point Of Sale all have Zapier apps listed in Zapier's directory with sale or customer triggers. Popular systems without a usable Zapier app include Zettle, Clover, Toast, Lightspeed Restaurant, and SumUp.
What if my POS is not on this list, like Zettle, Clover, SumUp, or Toast?
You can still use Leal. Zapier's directory lists dozens of other point of sale platforms, including Odoo, Biyo POS, and Final POS, and the same two-step setup works for any of them. If your till has no Zapier app, Leal runs alongside it: customers scan a QR code, save their stamp card to Apple Wallet or Google Wallet, and staff stamp it in seconds at the counter.
Can I add a loyalty program to my existing POS without switching?
Yes. If your POS is on Zapier, connect it to Leal in about 15 minutes with no code. If not, Leal runs alongside any till with QR code stamping, and open APIs allow deeper connections. You never need to change your till.
Do I need a developer to connect my POS to Leal?
Not for Zapier-supported systems, where setup is point and click. QR stamping alongside any other till needs no technical work either. Direct API connections involve development, and we are happy to help you scope them.
Keep your till. Add Leal.
