Square rings the sale fine, then strands the data away from your accounting and stock
When a Reading retail or hospitality operator finds Square or Toast rings sales well but strands the data away from accounting, stock and loyalty, a custom POS or integration layer pays off. Expect £40k to £110k over 3 to 6 months, with the integrated till live in about 9 weeks.
Square, Toast, Clover and Lightspeed are great at the moment of sale and weak at everything behind it. A Reading multi-site operator ends up exporting sales nightly to reconcile against accounting, with stock counts that don't match the floor and a loyalty scheme that lives in a separate app the till can't see.
The pain compounds across locations: each site's POS is an island, head office has no live view, and the transaction fees on an off-the-shelf processor quietly eat margin you can't easily reduce. You're paying a premium for a till that won't talk to the rest of your business.
The problems nobody warns you about
- Sales are exported nightly to reconcile against accounting by hand
- Stock in the POS drifts from the real floor count
- Loyalty lives in a separate app the till can't read
- Multi-site head office has no live, consolidated view
The case for owning your pos
A custom POS, or a custom layer over a hardware platform, integrates the till with your accounting software, inventory management software and loyalty so a sale updates everything at once. Head office gets a live multi-site view, you control the customer experience, and you can negotiate or route payments to protect margin.

What your build should include
Reading POS: the full scope
Everything a POS build here can cover: payment processing integration, custom POS system, point of sale software, retail POS, restaurant POS, Square alternative and Toast alternative.
Exactly what you get
A till that talks to the rest of your business: sales post to your accounting software, stock updates your inventory management software live, loyalty happens at the point of sale, and head office sees every Reading site in one view. It works offline and syncs back, and you gain control over payment routing to protect margin.
How to choose a developer in Reading
Demand real payments and PCI experience, because that's where custom POS projects sink. Ask how they handle the till going offline mid-service and how a sale reaches your accounting and inventory systems. For multi-site operators, confirm head office gets a live consolidated view. Often the smart build is a custom layer over reliable hardware rather than reinventing the terminal.
- !They wave away PCI, ask exactly how they scope payments compliance
- !No offline mode, ask what happens when the till loses connection
- !They skip accounting integration, ask how a sale reaches the ledger
- !No multi-site plan, ask how head office sees all locations live
- !They underrate reliability, ask how they prevent a checkout outage
Most Reading teams pricing pos end up comparing notes on supply chain, business intelligence dashboards, booking & scheduling too; the systems share one data spine.

Frequently asked questions
Should we replace Square entirely or integrate with it?
Often integrate. A custom layer over reliable POS hardware gives you the back-office integration, loyalty and multi-site reporting you lack without taking on the full burden of certified payment terminals. Full custom POS makes sense when you need deep control of the checkout and payment routing.
How do we handle PCI compliance?
Carefully, and with a developer who's done it. The cleanest path keeps card data out of your systems by using a compliant payment provider, so your PCI scope stays small. Anyone who shrugs at this question is the wrong team.
What happens if the till loses internet mid-service?
A well-built POS works offline, queues transactions and syncs when the connection returns. In-store downtime costs real money, so offline resilience is a core requirement, not a nice-to-have, especially across multiple Reading sites.
Will sales reach our accounting automatically?
Yes, that's a primary benefit. Each sale posts to your accounting software in near real time, killing the nightly export-and-reconcile routine and keeping your books current across every location.
Can it give head office a live multi-site view?
Yes. A custom POS consolidates every site into one live dashboard, so head office sees sales, stock and performance across the estate without waiting for each location to report, which off-the-shelf single-site tills can't do well.
