Built by engineers who spent years processing billions in card volume for major UK retailers — now designing the platform we wish independent businesses had always had.

Enterprise infrastructure. Independent pricing.

Payments that disappear into the background. So you can focus on the person in front of you.

Square was built for everyone. Sero was built for the independent café, restaurant, and bar owner who wants a platform that actually understands their day — and someone to call when it doesn't.

What actually matters
01
Named support,
not a ticket queue
When the terminal freezes mid-service you need a person — not a chatbot and a 48-hour SLA. Every Sero merchant has a named engineer who knows their setup.
2-hour response commitment during trading hours. A real phone number. A real person.
02
Stripe's rate,
passed through at cost
Most platforms mark up the payment rate and pocket the margin. We don't. Sero sits on Stripe Terminal and charges 1.4% + 10p — Stripe's rate, no platform padding.
No platform margin on top of processing. What Stripe charges us is what you pay.
03
Welsh market data,
not national averages
Benchmarks from London or Manchester tell you nothing useful if you're in Swansea. Sero aggregates anonymised data from Welsh venues so comparisons actually mean something.
Understand your trading patterns against comparable local venues — insight no national platform can offer.
01 / 03
Take payments.
Reliably.
Stripe Terminal at the core. Contactless, chip and PIN, Apple Pay, Google Pay. Server-driven so a tablet crash mid-service never takes the till down with it.
02 / 03
Know your regulars.
Automatically.
Card-linked loyalty that works with the card your customers already carry. No app, no stamp card. Sero recognises them every time they tap.
03 / 03
Understand your
trading patterns.
Anonymised, aggregated Welsh market data. How does your busiest hour compare to similar venues? Regional insight no national platform can offer.

“
“We spent years building payment infrastructure for major UK retailers — systems handling billions in annual card volume. Then we looked at what independent hospitality businesses were being offered. We couldn't believe the gap. Sero exists to close it.”
