Custom POS Development for Retail and Hospitality

We build point-of-sale systems that stay fast at peak times, keep trading when the internet drops and sync sales, stock and customers across every location.

Why build a custom POS?

Cloud POS products work well for single shops with standard needs. Custom POS development becomes worthwhile when you run many locations, have unusual pricing or product rules, need deep integration with your ERP or e-commerce platform, or want to stop paying per-terminal fees on hundreds of tills.

For many businesses a middle path works best: start from our proven POS software core and customise the parts that make your operation different.

What a modern POS needs

Checkout speed

Every second at the till matters at peak times. We design for minimal taps, fast barcode scanning, quick-access product grids and keyboard shortcuts for experienced staff.

Offline-first operation

Internet outages should never stop sales. Our POS terminals store products, prices and customers locally, take card and cash payments offline where the payment provider allows, and sync automatically when the connection returns — with conflict handling for stock levels.

Real-time stock and multi-store sync

Sales update stock immediately, transfers between stores are tracked, and head office sees consolidated figures across all locations.

Payments integration

Integrated card terminals through providers such as Stripe Terminal, Adyen, Square or local acquirers, plus split payments, gift cards, deposits and refunds with proper audit trails.

Retail and hospitality features

For restaurants specifically, see our restaurant management software.

Hardware and platforms

We build POS front ends as installable desktop apps, Android and iPad apps or browser-based terminals, depending on your hardware. Receipt printers, cash drawers, scanners, scales and customer displays are supported through standard drivers.

What our clients say

• We used to lose half a day's takings every time a store's broadband went down. Since the new tills went in, outages barely register, and head office can change a price at lunchtime and see it on every shelf-edge promotion by the afternoon.

• Parents now have one app instead of four, and our office teams have stopped spending Monday mornings chasing absence calls. The migration was the part we worried about most, and the trial runs meant there were no surprises on go-live day.

• The assistant resolves the repetitive how-do-I questions and hands everything else to us with a proper summary. Our agents spend their time on the tricky tickets now, and customers get answers at 2am without us adding a night shift.
