Restaurant POS System UK: A 2026 Buyer's Guide for Independents

A restaurant POS is the till, the kitchen ticket printer, and the order brain that ties everything together. UK independents in 2026 have more options than ever, but the pricing is increasingly opaque. This guide walks through the real costs and trade-offs of every credible POS option, and where an integrated ordering app changes the maths.

What a restaurant POS actually has to do

A modern POS for a UK independent needs to do six things well: take orders at the counter, route those orders to the kitchen, handle payment (card and cash), track stock and reporting, integrate with your ordering app, and run reliably during a Friday-night rush. Anything that fails on the last point is a non-starter regardless of price.

The UK POS landscape in 2026

The hidden costs nobody talks about

• Payment processing markup. Most POS providers force you onto their card processor (Square Payments, Lightspeed Payments, etc.) at 1.6% to 2.5%. Aexir lets you use Stripe at the standard 1.5% + 20p.
• Hardware lock-in. Toast hardware works only with Toast software. Square hardware works only with Square. Aexir bundles a generic Android tablet you can repurpose if you ever leave.
• Per-add-on subscriptions. "Online ordering" is almost always a paid add-on with the big POS players (£30 to £100/month). Aexir includes ordering, loyalty, and analytics in the base subscription.
• Per-station fees. Lightspeed charges per till station; running three tablets in your dining room is three times the cost.
• Setup and migration fees. £200 to £1,500 one-time, depending on provider.
• 24-month contracts. Square is monthly. Most others lock you in for 12 to 24 months. Read the small print.

When the big POS players are right

There are cases where a specialised POS beats the integrated approach.

• You run a full-service restaurant with complex floor plans, table management, course-pacing, and split bills. Toast and Lightspeed handle this well; integrated app-led POS less so.
• You operate 10+ locations and need centralised reporting and inventory across the group. Lightspeed Restaurant's reporting is genuinely strong.
• You take 80% of orders in-person and need stock management down to the ingredient level (a butcher's shop with a kitchen counter, for example). The big POS players are better at this than ordering-first builders.

When an integrated app-led POS wins

For UK independents that take a significant share of orders via app, web, and delivery, an integrated approach beats a bolt-on every time. Here is the maths.

1. Single source of truth for orders. App orders, website orders, QR table orders, walk-in orders, all flow through the same dashboard. No tab-switching, no reconciliation pain.
2. Loyalty credits across every channel automatically. A walk-in regular who pays with cash can still earn loyalty stamps via the till; the dedicated POS players treat in-store and online as separate worlds.
3. One subscription, not seven. Aexir at £31/month covers POS, ordering app, branded website, loyalty, analytics, and push notifications. The Lightspeed equivalent stack is £200+ per month.
4. Hardware costs lower. £149 tablet + £199 printer = £348 one-time. Compare to a Toast or Lightspeed dedicated terminal at £500 to £1,500.

Decision tree for choosing

1. Do you take more than 30% of orders via app, web, QR, or delivery? If yes, an integrated app-led POS (Aexir) is the right answer. If no, consider Square (cheap) or Lightspeed (capable).
2. Do you run more than one location with shared stock? If yes, Lightspeed scales better; check whether you need its inventory-management depth. If you just need shared menus and analytics, Aexir handles multi-location at £1 per day per extra location.
3. Do you want to be free of card-processor lock-in? Choose a POS that lets you use Stripe or Adyen directly. Square and Lightspeed force their own processors.
4. Are you on a tight budget for year one? Aexir or Square Free Tier. Avoid the £500+ hardware bundles unless your floor plan demands them.
