Let's cut through the noise. You're here because you need a proper POS system for your UK business, and you're tired of vague marketing fluff that doesn't tell you what things actually cost or how they work in real life.
We've tested the lot, looked at actual pricing (not just "contact us for a quote" nonsense), and we're going to give you the honest breakdown. Whether you're running a café in Manchester, a boutique in Brighton, or a restaurant in Edinburgh, here's what you need to know.
What Actually Matters in a POS System
Before we dive into specific systems, let's talk about what you should actually care about:
Reliability – Can it handle a busy Saturday without crashing? Does the barcode scanner work every time, or will you be typing in product codes manually whilst a queue builds up?
Real-world pricing – We're talking about the actual monthly costs, transaction fees, and hardware expenses. Not the marketing price that magically doubles once you need basic features.
Inventory that works – Real-time stock tracking across locations isn't a luxury anymore. It's essential if you want to avoid selling stuff you don't have.
Proper support – When your till goes down at 6 PM on a Friday, can you actually reach someone who'll help?
Right, let's look at the systems that actually deliver.
Square POS – The Reliable All-Rounder
Square's become massive in the UK for good reason. It's genuinely free to start, and the pricing is refreshingly transparent.
What it costs: No monthly fees for the basic plan. You pay 1.75% per transaction for in-person card payments. Hardware is straightforward – the Square Terminal is £249, the Stand is £119, and the Register is £649.
What we like: The inventory management is solid, returns are simple to process, and it works brilliantly for cafés and quick-service restaurants. The reporting is actually useful, not just pages of numbers you'll never look at.
The catch: Limited table management features if you're running a full-service restaurant. It's built for speed and simplicity, which means some advanced hospitality features aren't there.
Best for: Coffee shops, quick-service restaurants, small retail shops, market stalls.
Shopify POS – If You're Selling Online Too
If you've already got a Shopify website or you're planning to sell online alongside your physical shop, Shopify POS makes complete sense.
What it costs: Plans start at £24/month, but you'll realistically need the £79/month plan for proper POS features. Plus transaction fees unless you use Shopify Payments.
What we like: Everything syncs perfectly between your online store and physical location. Stock levels update automatically, and you can see all your sales data in one place. The analytics are genuinely comprehensive.
The catch: It's more expensive than other options, and if you're not bothered about selling online, you're paying for features you won't use.
Best for: Retailers who need omnichannel capabilities, fashion boutiques, gift shops with online stores.
Epos Now – The UK Independent's Choice
We've reviewed Epos Now extensively, and it's particularly popular with UK independent retailers for solid reasons.
What it costs: Hardware packages from around £599, with software starting at £25/month per terminal. Transaction fees vary depending on your payment processor.
What we like: It's designed with UK businesses in mind, the customer service is reliably helpful (rare in this industry), and the hardware is robust. The system handles complex inventory well, including variants and multi-location stock control.
The catch: The eCommerce integration isn't as slick as Shopify's. If online selling is a major part of your business, you might find it limiting.
Best for: Independent retailers, bakers, grocers, convenience stores, hospitality venues.
The Epos Now system also offers some clever features like multiple-choice products for upselling, which we've covered in detail in our upselling guide.
Lightspeed – When You Need Everything
Lightspeed is the comprehensive option. It's got features you didn't even know you needed.
What it costs: £89/month for the Basic plan, up to £229/month for the Plus plan, per location. Plus volume-based transaction fees (roughly £75 for sales up to £15,000). This adds up quickly.
What we like: Advanced inventory management, built-in eCommerce, loyalty programmes, detailed staff management, and analytics that actually help you make decisions. The hardware is proprietary and well-designed.
The catch: Most of the good features require the more expensive plans. You're looking at significant monthly costs, especially for multiple locations. There's also a learning curve – this isn't a simple system.
Best for: Growing retailers with complex inventory needs, multi-location businesses, fashion retailers, specialty stores.
SumUp – The Budget Champion
SumUp has become a go-to for UK small businesses watching their costs.
What it costs: No monthly fees. Transaction fees are 1.69% for card payments. The Solo card reader is £29, the Air is £49, and their POS system starts around £269.
What we like: Ridiculously low barrier to entry. Perfect for new businesses testing the waters. The card readers are reliable, and the app is intuitive.
The catch: Limited features compared to full POS systems. Fine for simple retail or market stalls, but you'll outgrow it quickly if your business gets busy or you need proper inventory management.
Best for: Market traders, pop-up shops, mobile businesses, very small cafés.
Clover POS – The Middle Ground
Clover sits between budget and premium options, offering decent hardware and a massive app marketplace.
What it costs: This is where it gets murky. Pricing isn't clearly displayed on their website, which is always a red flag. Hardware ranges from around £400 to £1,200, with monthly fees varying by plan. Get quotes before committing.
What we like: Sleek hardware, huge selection of third-party apps, straightforward returns management. The ecosystem is extensive if you need specific integrations.
The catch: Hidden fees. The lack of transparent pricing makes it difficult to budget accurately. Some users report customer service issues.
Best for: Small to medium businesses wanting customisation through apps.
POSApt – The Hospitality Specialist
POSApt is designed specifically for restaurants, bars, and hospitality businesses managing multiple locations.
What it costs: Custom pricing based on your requirements. You'll need to request a quote.
What we like: Built for hospitality, so features like table management, split bills, and kitchen display systems are properly thought through. Multi-location management is particularly strong.
The catch: Custom pricing means you can't easily compare costs. It's hospitality-focused, so not ideal for retail.
Best for: Restaurants, bars, cafés with multiple locations, hospitality groups.
The Honest Pricing Breakdown
Here's what you're actually going to pay:
Budget tier (£0-£50/month): Square, SumUp
- Best for: New businesses, market stalls, simple retail
Mid-range (£50-£150/month): Epos Now, Shopify POS
- Best for: Independent retailers, small restaurant chains, growing businesses
Premium (£150+/month): Lightspeed, POSApt
- Best for: Multi-location businesses, complex inventory needs, established operations
Don't forget to factor in transaction fees (typically 1.5-2.5% per card payment) and hardware costs (£250-£1,000+ depending on your needs).
What We'd Actually Choose
If we were opening a shop in the UK tomorrow, here's what we'd pick:
For a café or quick-service restaurant: Square or Epos Now. Both handle busy periods well, and the pricing is transparent.
For retail with online sales: Shopify POS, no contest. The integration is too good to ignore.
For an independent retailer: Epos Now. The UK-focused support and reliable hardware make a real difference.
For a full-service restaurant: POSApt or Lightspeed, depending on your budget and complexity needs.
According to research from Retail Gazette, UK retailers are increasingly prioritising integrated POS systems that handle both in-store and online sales, making omnichannel capabilities essential for 2026.
The Bottom Line
There's no single "best" POS system – it depends on your business type, budget, and what features you actually need (not just what sounds impressive in marketing materials).
Square and SumUp are brilliant for starting out with minimal investment. Epos Now is solid for UK independent retailers who want proper support. Shopify POS makes sense if you're selling online. Lightspeed is comprehensive but expensive.
The most important thing? Get demos of your top two or three choices and test them with real scenarios from your business. See how they handle a busy period, process returns, and manage inventory. The system that feels intuitive to you and your staff is usually the right one.
Don't let salespeople rush you into contracts, watch out for hidden fees, and make sure you understand the total cost of ownership – not just the attractive monthly price they lead with.
