Square skims a percentage of every pint and portion across your Hull venues, and it adds up fast
If you run multiple Hull venues or market stalls and Square or Toast takes a cut of every transaction while still not quite fitting your trade, a custom POS removes the per-transaction skim and matches how you actually sell. Expect £45,000 to £130,000 over 4 to 7 months, justified by volume.
Square, Toast, Clover and Lightspeed are quick to set up and take a slice of every sale forever. For a Hull operator doing meaningful volume across a regenerated city-centre venue, a market presence and events, those percentages compound into a number that would have funded a system you own. And the off-the-shelf till still imposes its own model: it struggles with market-stall mobility, multi-venue stock and pricing, or the specific service flow of a busy local venue.
The trade-off most operators don't run is straightforward. Below a certain transaction volume, the convenience of Square is worth the fee. Above it, you're paying a recurring tax on your own success for a system that doesn't fully fit. A custom POS flips that: a larger up-front cost, then your own till that matches your trade and stops skimming every transaction.
The fix: pos built for Kingston upon Hull, not rented
At sufficient volume, owning your POS beats renting one that taxes every sale. A custom build matches your service flow, syncs stock and pricing across venues and market stalls, works offline when the connection drops, and removes the per-transaction fee. The maths is volume-driven: once the fees you're paying Square would amortise a build in a couple of years, the custom route stops being a luxury and starts being a saving.

How long it takes, phase by phase
Exactly what you get
A till you own instead of one that taxes every sale. It matches your service flow, syncs stock and pricing across your Hull venues and market stalls, keeps working when the signal drops at an event, and processes payments without the per-transaction skim. Sales reconcile straight into your accounting software, and the whole thing is built around how you trade rather than a generic hospitality template.
How to choose a developer in Hull
Pick a team that runs the break-even maths with you before anything else, because a custom POS only makes sense above a real volume. Ask them to show the payback against your current Square or Toast fees, and how they handle PCI compliance and offline selling at a market stall. A developer who integrates the till with your accounting and inventory software, rather than leaving it standalone, is the one who turns the fee saving into a system that actually fits.
- No per-transaction fee skimming every sale across your venues and stalls
- Stock and pricing synced across multiple Hull locations in real time
- Offline-resilient operation for market stalls and events where signal drops
- A service flow matched to your venues rather than a generic hospitality template
- Integration with your accounting software, inventory management software and booking software
- High up-front cost that only pays back above a real transaction volume
- You own payment-processing integration and PCI compliance, not a vendor
- Hardware support and updates become your responsibility
- Below the volume threshold, Square or Toast is genuinely the cheaper choice
- !They don't ask your transaction volume. Ask them to show the break-even versus Square fees.
- !No offline plan for stalls and events. Ask what happens when the signal drops mid-sale.
- !They wave off PCI compliance. Ask exactly how payments and card data are handled.
- !No multi-venue sync plan. Ask how stock and pricing stay consistent across locations.
- !No accounting integration. Ask how sales reconcile to your books.
If pos is on the roadmap, supply chain, business intelligence dashboards, booking & scheduling usually follow within the year. Budget them as one conversation.

Frequently asked questions
When does a custom POS beat Square?
It's volume-driven. Below a certain transaction volume, Square's convenience is worth the per-sale fee. Once those fees would amortise a build in roughly two years, owning your POS becomes the cheaper option, especially across multiple Hull venues where the fees stack up.
What about offline selling at markets and events?
A custom POS is built offline-resilient, so it keeps taking sales when the signal drops at a market stall or event and syncs when the connection returns. That's a common failure point for off-the-shelf tills in those settings.
Who handles payment processing and PCI?
With a custom POS you integrate a payment processor and take on PCI compliance responsibility, which a good developer designs in from the start. It's more responsibility than Square's all-in-one, which is exactly why the volume has to justify it.
Can it sync stock across our venues?
Yes, that's a core reason to go custom. Stock and pricing sync in real time across venues and stalls, so you're not reconciling separate tills by hand. It also integrates with your inventory management software and accounting software.
What's the ongoing cost?
Budget £16,000 to £34,000 a year for support, payment maintenance and hardware. You're taking on what Square bundled into its fee, so factor that in when running the break-even, though at real volume the saving still favours custom.
