Choosing the right epos system is probably one of the most stressful decisions you’ll make as a business owner. Whether you’re just starting out with a boutique shop in the Cotswolds or managing a busy gastropub in Manchester, the "till" is no longer just a box where you keep the cash. It’s the brain of your business.
We get it, there are hundreds of options out there, each claiming to be the best pos system on the market. It’s easy to get lost in a sea of jargon about "cloud-based APIs" and "omnichannel integration." At What EPOS, we’ve spent years testing these systems so you don’t have to. We’ve seen which ones hold up during a Friday night rush and which ones leave you staring at a spinning loading icon while your customers get impatient.
In this guide, we’re going to break down how to choose the right system for your specific needs, compare the big hitters like SumUp POS, Shopify POS, and Epos Now till system, and help you find the cheapest pos system that doesn't sacrifice quality.
What Exactly Should You Look For?
Before you start looking at shiny hardware, you need to know what your business actually needs. A retail pos system needs to handle thousands of SKUs and complex inventory, while a restaurant pos system needs to manage table layouts, split bills, and kitchen communication.
Here are the four big things we always tell our clients to look for:
1. Operational Reliability
This is non-negotiable. If your internet goes down, does your business stop? The best systems have an "offline mode" that allows you to keep taking card payments and processing orders even if the Wi-Fi decides to take a nap. According to industry insights from UKHospitality, operational downtime is one of the biggest hidden costs for UK SMEs.
2. Subscription vs. Ownership
This is a bit of a "choose your own adventure" moment. Some systems, like Square POS or SumUp POS, have low upfront costs but take a bigger slice of every transaction. Others might require a monthly subscription. We generally find that for growing businesses, a system with a solid support structure, like the Epos Now till system, provides the best balance of features and long-term value.
3. Real-Time Inventory Control
If you’re selling both in-store and online, you need a system that talks to itself. There’s nothing worse than selling the last pair of shoes in your shop while someone just bought them on your website two minutes ago. Shopify POS is great for this, but many dedicated EPOS systems now offer even deeper inventory tracking.
4. UK-Based Support
When things go wrong, and eventually, something will, you don’t want to be waiting for a support centre in a different time zone to wake up. We always recommend choosing a provider with a strong UK presence and 24/7 support.
The Big Comparison: Which One Wins?
Let's look at the heavyweights. We've spent a lot of time reviewing these, and honestly, the "best" depends entirely on your setup.
Epos Now: The All-Rounder (Our Top Pick)
If you’ve spent any time on our site, you’ll know we’re big fans of Epos Now. It’s built specifically for the UK market and handles both retail and hospitality with ease. It’s incredibly scalable, meaning it grows with you. Whether you’re a single coffee cart or a 10-location chain, it just works.
We’ve written a massive, deep-dive Epos Now review page here that covers everything from hardware feel to software glitches. If you’re serious about upgrading, it’s the first place you should look. It’s arguably the most balanced epos system for UK small businesses in 2026.
SumUp POS: The Small Business Favourite
If you’re looking for the cheapest pos system to get started, SumUp POS is hard to beat. It’s tiny, sleek, and the "no monthly fee" model is very tempting for weekend market traders. However, as you grow, those transaction fees can start to bite. You might want to check out our thoughts on how much SumUp charges per transaction before you commit.
Shopify POS: The E-commerce King
For those who started on the web and are now moving into a physical space, Shopify POS is the natural choice. It syncs your online and offline worlds perfectly. The downside? It can get expensive quickly once you start adding the "Pro" features you’ll likely need for a busy shop.
Toast POS: The Hospitality Specialist
Toast POS has been making waves recently. It’s built by people who clearly understand the chaos of a kitchen. However, for UK businesses, it faces stiff competition from established local players who offer better pound-for-pound value.
Industry Specific: What Do You Actually Need?
For Restaurants and Cafes
A restaurant pos system needs to be fast. We're talking "Friday night rush with a line out the door" fast. You need features like:
- Table management and floor plans.
- Kitchen Display Systems (KDS).
- Easy bill splitting (because nobody carries cash anymore).
- Integration with delivery apps like Deliveroo or UberEats.
If you’re on a tight budget, check out our guide on the cheapest POS systems for restaurants.
For Retail Stores
A retail pos system is all about the data. You need to know what’s selling, what’s gathering dust, and who your best customers are. Look for:
- Robust barcode scanning.
- Customer Loyalty programmes.
- Multi-location stock tracking.
- Ease of use for temporary staff.
The Costs: What’s the Real Price Tag?
It’s easy to get lured in by a "£0 upfront" offer, but you have to look at the Total Cost of Ownership (TCO). Between hardware, software subscriptions, and payment processing fees, the costs can add up.
- Hardware: You can expect to pay anywhere from £150 for a basic tablet stand to £1,500+ for a full dual-screen setup with scales and scanners.
- Software: Monthly fees usually range from £20 to £100 per terminal.
- Payments: This is where they get you. Most providers charge between 1.2% and 2.5% per transaction.

Common Pitfalls to Avoid
We’ve seen a lot of business owners make the same mistakes. Here’s how to avoid them:
- Don't get locked into long contracts: Some providers try to tie you in for 3 to 5 years. In the tech world, that’s an eternity. Stick to rolling monthly or 12-month terms if you can.
- Check the hardware quality: Cheap plastic touchscreens will break. If you’re in hospitality, make sure your hardware is "spill-resistant."
- Hidden "Integration" fees: Some companies charge extra just to connect your accounting software (like Xero or QuickBooks). Always ask about this upfront.
