Choosing an epos system shouldn't feel like a trip to the dentist. We know, we know: looking through endless feature lists and pricing tables is probably the last thing you want to do after a long shift at the shop or restaurant. But here’s the thing: in 2026, your point of sale isn't just a fancy cash drawer. It’s the brain of your entire operation.
Whether you're opening a new bakery in Bristol or upgrading a busy boutique in London, the right pos system can be the difference between a smooth Saturday rush and a total technical meltdown. At What EPOS, we’ve spent years testing these systems so you don't have to.
In this guide, we’re breaking down the top five providers in the UK right now. We’ll look at the best pos system options for different budgets, the cheapest pos system for those just starting out, and why one particular name: Epos Now: consistently tops our list for UK business owners.
Why Your Choice Matters More in 2026
The world of retail and hospitality has changed a lot over the last couple of years. Customers expect everything to be fast, personalised, and "omnichannel" (which is just a fancy way of saying they want to buy online and pick up in-store without any hiccups).
A modern epos system handles your inventory, tracks your staff hours, manages your loyalty programs, and syncs with your accounting software like Xero or Sage. If your current system feels like it’s holding you back, it probably is.
Before we dive into the providers, if you want the short version: we consistently recommend Epos Now for most UK businesses. You can check out our full Epos Now till system review to see why it’s our top pick for 2026.
1. Epos Now: The Best All-Rounder for UK Businesses
We’ll start with our favourite. Epos Now has been a dominant force in the UK market for years, and for good reason. They offer a perfect balance of advanced features and ease of use. Whether you need a restaurant pos system with table management or a retail pos system with deep inventory tracking, they’ve got a tailored solution.
What we love most about the epos now till system is its flexibility. It doesn’t matter if you’re a single-site coffee shop or a multi-location retail chain; the software scales with you. Their AppStore is also massive, allowing you to connect to things like Shopify, Mailchimp, and various delivery platforms.
Pros:
- UK-based 24/7 support (huge when things go wrong at 9 PM on a Friday).
- Industry-specific hardware that actually looks good on a counter.
- Very competitive pricing for the features you get.
Cons:
- The sheer number of features can be a bit overwhelming at first.
If you’re serious about growing your business this year, it’s definitely worth looking at our comprehensive Epos Now review. They often have some great hardware bundles that make them one of the most cost-effective ways to get a professional setup.
2. Square: Best for Flexibility and No Monthly Fees
Square has become a household name, and it’s easy to see why. If you’re looking for a low-barrier entry, Square is often the go-to. Their "no monthly fee" model for the basic software is a big draw for seasonal businesses or startups.
While they are often considered the cheapest pos system in terms of upfront software costs, keep an eye on those transaction fees. They can add up quickly as you grow. Square is fantastic for mobile businesses: think food trucks or market stalls: because their hardware is sleek and very portable.
However, when you compare Epos Now vs SumUp vs Shopify POS, you’ll see that while Square is flexible, some businesses find their customer support a bit harder to reach during an emergency compared to UK-centric providers.
3. SumUp: The Cheapest POS System for Small Startups
If you are just starting out and every penny counts, the sumup pos is likely on your radar. It is incredibly simple to set up. You can literally buy a card reader, download the app, and be taking payments in minutes.
SumUp is great if you don't need complex features like table layouts or advanced stock recipes. It’s a "what you see is what you get" system. We’d say it’s the cheapest pos system for micro-businesses, but as soon as you start growing, you might find yourself hitting a wall in terms of what the software can do.
4. Shopify POS: The King of Retail
For those who started as an e-commerce brand and are now moving into physical stores, shopify pos is a no-brainer. The way it syncs your online stock with your in-store inventory is seamless.
It’s a top-tier retail pos system, but it can get expensive. You need a Shopify subscription to use it effectively, and the "Pro" version of the POS software comes with an extra monthly cost per location. It’s a powerful tool, but maybe a bit much if you don't have a major online presence.
5. Toast POS: The Specialist for Restaurants
If you run a high-volume eatery, you’ve probably heard of toast pos. Originally massive in the US, they’ve made significant inroads into the UK. As a dedicated restaurant pos system, it handles things like kitchen display systems (KDS) and tableside ordering better than almost anyone else.
The downside? It can be pricey, and their contracts are known to be a bit more "locked-in" than others. For a smaller cafe, it might be overkill, but for a busy bistro, it’s a contender.

How to Choose: What Should You Look For?
Choosing the best pos system isn't just about picking the one with the coolest logo. You need to think about your daily workflow. Here’s our checklist for what you should be asking providers:
1. What’s the total cost of ownership?
Don't just look at the hardware price. Ask about monthly software fees, transaction rates, and any "hidden" costs like menu setup fees or premium support charges. According to data from the British Retail Consortium, payment processing costs are a major concern for UK SMEs, so make sure you understand the "effective rate" you'll be paying.
2. Is the hardware durable?
In a busy restaurant, things get spilled. In a retail shop, things get dropped. You need hardware that can survive the "real world." This is another reason we like the epos now till system: their water-resistant screens and sturdy stands are built for the hospitality grind.
3. How good is the UK support?
We cannot stress this enough. If your system goes down on a busy Saturday, you don't want to be waiting for a support centre in a different time zone to wake up. Look for providers with 24/7 UK-based support.
Industry-Specific Advice
For Restaurants
You need a restaurant pos system that can handle modifications. "No onions, extra cheese, dressing on the side": if your system makes that hard to input, your kitchen staff will hate you. Look for features like "held orders" and easy split-billing.
For Retailers
Your retail pos system should be an inventory master. It should tell you when you’re low on a specific SKU and ideally generate purchase orders automatically. Integration with your website is no longer a "nice to have": it’s essential.
The Verdict: Which System Wins in 2026?
So, who takes the crown?
If you are a tiny business or a hobbyist, SumUp or Square are your best bets for staying lean. If you are a retail giant in the making, Shopify is your friend.
However, for the vast majority of UK small-to-medium businesses: the pubs, the boutiques, the busy cafes, and the local shops: we believe Epos Now is the winner. It offers the most comprehensive feature set for the price, and their commitment to the UK market is unmatched.
