It’s 2026, and the days of a simple cash register sitting on a counter are long gone. Whether you’re running a bustling boutique in Manchester or a trendy bistro in London, your epos system is now the heartbeat of your entire operation. It handles your sales, tracks your inventory, manages your staff, and even helps you keep your customers coming back with loyalty schemes.
But with so many options on the market, how do you actually pick the best pos system for your specific needs? We know it’s a bit of a minefield out there. You’ve got big global names, local UK specialists, and a whole range of pricing structures that can make your head spin.
At What EPOS, we’ve spent years testing these systems so you don’t have to. In this guide, we’re going to break down the top contenders for 2026, look at the costs, and help you decide which one will help your business thrive.
Why Choosing the Right EPOS System Matters More Than Ever
In the current climate, efficiency is everything. With the UK's ongoing labour market shifts, having a system that is easy to use means you can get new staff trained in minutes, not days. On top of that, with the cost of doing business still a major talking point, finding the cheapest pos system that doesn't sacrifice quality is a top priority for many.
Your pos system isn't just about taking payments anymore; it’s about data. It’s about knowing that you’re running low on sourdough at 11:00 AM on a Tuesday or seeing that your Friday night cocktail happy hour is actually losing you money.
If you’re looking for a solid all-rounder that we consistently recommend for its versatility, you should definitely check out our Epos Now till system review. It’s a great starting point for any UK business owner.
Key Factors to Consider Before You Buy
When you’re comparing systems like SumUp POS, Shopify POS, or Epos Now, there are four main things we think you should keep in mind:
1. Your Industry
A restaurant pos system needs very different features compared to a retail pos system. Restaurants need floor plans, kitchen display screen (KDS) integrations, and "course firing" capabilities. Retailers, on the other hand, need robust inventory management and barcode scanning.
2. Budget and Pricing Structure
Don’t just look at the upfront cost of the hardware. You need to look at:
- Monthly Software Fees: Can range from £0 to over £100.
- Transaction Fees: Usually a percentage of every sale (e.g., 1.75%).
- Hardware Costs: The cost of the tablets, stands, and card readers.
3. Ease of Use
If the system is too complex, your staff will hate using it, and you'll end up with errors in your data. Systems like Square are famous for their simplicity, but they might lack the deep customisation that a more robust epos system offers.
4. Integration
Does it talk to your accounting software like Xero or Sage? Does it connect to your online shop? If it doesn’t, you’ll end up doing hours of manual data entry, which is a massive waste of your time.
Top POS System Contenders for 2026
Let’s look at some of the heavy hitters in the UK market right now and see how they stack up.
Epos Now: The Versatile All-Rounder
We’re big fans of Epos Now because they offer tailored solutions for both retail and hospitality. Whether you're a small corner shop or a multi-site restaurant group, they have the hardware and software to match. Their system is incredibly scalable, which is why it’s often cited as one of the best pos system choices in the UK.
If you're curious about how they handle specific business needs, we’ve put together a very detailed Epos Now review that covers everything from pricing to customer support.
Square: The King of Simplicity
Square is often the go-to for startups and small businesses. There’s no monthly fee for their basic plan, which makes it one of the most accessible options out there. However, their transaction fees (usually around 1.75%) can start to bite as your turnover grows. It's a great "plug and play" option, but you might find you outgrow it as your operations get more complex.
Shopify POS: Best for Omnichannel Retail
If you already sell online using Shopify, then using Shopify POS in your physical store is a no-brainer. It syncs your inventory perfectly so you never sell something in-store that just sold online five minutes ago. It's one of the best retail pos system options for modern brands. You can read our full thoughts on this in our Shopify POS review.
Toast POS: The Restaurant Specialist
When it comes to a dedicated restaurant pos system, Toast POS is a massive name that has moved over from the US and really made a mark in the UK. It’s built by restaurant people for restaurant people. Everything from the handheld ordering tablets to the kitchen displays is designed to speed up service.
Comparing the Costs: What Will You Actually Pay?
It’s easy to get lured in by a "free" system, but as we always say, nothing is truly free in the world of payments.
| System | Monthly Fee | Transaction Fee | Best For |
|---|---|---|---|
| Epos Now | From £25 | Custom/Competitive | All-round versatility |
| SumUp POS | From £0 | ~1.69% | Small cafes/Mobile businesses |
| Square | £0 (Basic) | 1.75% | Micro-businesses |
| Shopify POS | From £25 | Varies | Omnichannel Retail |
| Lightspeed | From £59 | ~1.6% | High-end Hospitality |
For businesses with a high turnover, paying a monthly fee to get a lower transaction rate is almost always the smarter move. For example, if you’re doing £20,000 a month in card sales, a 0.5% difference in transaction fees saves you £100 a month: which easily covers a software subscription.

Choosing by Business Type
The Best POS for Small Retailers
For a small shop, you want something that handles returns easily and lets you see what your best-selling items are. Epos Now and Shopify POS are the frontrunners here. If you're on a tight budget, look into SumUp POS as well. We’ve covered their portable options in our SumUp POS system review.
The Best POS for Restaurants and Pubs
In a busy kitchen, you need reliability. According to UKHospitality, technology adoption is key to tackling the current margin squeeze in the industry. You need a system that can handle "split bills," "table management," and "modifiers" (like "no onions" or "extra cheese") without breaking a sweat. Toast POS and Epos Now are excellent in this regard.
Is Epos Now the Right Choice for You?
We often point our readers towards Epos Now because they strike a really good balance between feature-rich software and affordable hardware. They offer 24/7 support, which is a lifesave if your system goes down on a busy Saturday night.
Some of the things we love about the Epos Now till system include:
- The App Store: You can add extra features (like loyalty or accounting) only when you need them.
- Hardware Quality: Their tills are built for the "rough and tumble" of a retail or kitchen environment.
- Cloud-Based: You can check your sales figures from your phone while you're sitting on a beach (if you're lucky enough to get a holiday!).
It’s definitely worth taking five minutes to read our comprehensive Epos Now review to see if it fits your specific business model.
