Finding the right retail pos system can feel like a bit of a minefield, can’t it? Whether you’re just starting a small boutique or you’re looking to upgrade an existing setup for multiple locations, the sheer amount of choice out there is enough to make anyone’s head spin.
In 2026, a till isn’t just a place to keep cash anymore. It’s the brain of your business. It handles your inventory, tracks your staff, manages your online sales, and: most importantly: makes sure you actually get paid. We know you’re busy running your shop, so we’ve done the legwork for you.
Today, we’re breaking down three of the biggest names in the industry: SumUp, Shopify, and Epos Now. We'll look at who they’re for, what they cost, and which one we think is the best pos system for your specific needs.
Why Your Choice of EPOS System Matters
Before we dive into the comparison, it’s worth thinking about what you actually need from your hardware and software. A budget-friendly option might seem great on day one, but if it can't grow with you, you'll end up spending more in the long run to switch.
When you're looking for an epos system, you should be thinking about:
- Ease of Use: Can you train a new staff member in 15 minutes?
- Inventory Management: Does it tell you when you’re low on stock?
- Reliability: What happens if the Wi-Fi goes down on a busy Saturday?
- Cost: Is there a hefty monthly fee, or do you just pay per transaction?

SumUp: The King of Simplicity
If you’re looking for the cheapest pos system to get started, SumUp is usually the first name that pops up. It’s incredibly popular for mobile businesses, pop-up shops, and market stalls.
Why we like SumUp
The biggest draw for SumUp POS is the lack of commitment. There are often no monthly subscriptions for the basic setups, and the hardware is very affordable. You buy the card reader, download the app, and you’re ready to go.
It’s a "pay-as-you-grow" model. You’ll pay a flat percentage on every transaction (usually around 2.75% for in-person payments), which is great if your sales volumes are low or inconsistent.
Where it falls short
SumUp is great for basic sales, but it starts to struggle as you get bigger. If you have a massive inventory or want deep insights into your profit margins, you might find the reporting a bit thin. It’s also not really designed for managing multiple locations or complex staff permissions.
Best for: Startups, mobile traders, and small retailers with low transaction volumes.

Shopify POS: The E-commerce Giant
If you already sell online using Shopify, then using their retail pos system is almost a no-brainer. The integration between your website and your physical shop is seamless.
Why we like Shopify POS
The real magic here is the unified inventory. If someone buys a t-shirt on your website at 2 AM, your shop floor inventory updates automatically. No more awkward "sorry, we're actually out of stock" emails.
It’s very user-friendly and looks great on an iPad. It also handles "buy online, pick up in-store" (BOPIS) better than almost anyone else.
The downside
It can get expensive. On top of your monthly Shopify subscription, you’ll likely want the "POS Pro" version to get features like staff roles and advanced reporting. Also, if you aren't using Shopify for your website, it's probably not the right choice for your physical till.
Best for: Existing Shopify users and businesses where online sales are just as important as in-store sales.

Epos Now: The Versatile Heavyweight
When we talk about the best pos system for retail growth, we often point people toward Epos Now. It sits in that sweet spot where it's powerful enough for large enterprises but accessible enough for a single independent shop.
Why we like Epos Now
What sets the Epos Now till system apart is its sheer flexibility. It doesn't matter if you're running a boutique, a pharmacy, or a hardware store; the software is highly customisable to your industry.
One feature we really love (especially in 2026) is the Standalone Mode. We’ve all been there when the internet cuts out and you can’t take payments. Epos Now has built-in 4G and WiFi backups that ensure you never have to turn a customer away. On top of that, their inventory management is top-tier: it handles automated purchase orders and tracks every penny of your profit margin.
The trade-off
Because it has so many features, the learning curve is slightly steeper than SumUp. However, most people find they can get the hang of the basics in about 15 minutes. It’s a robust, professional system built for businesses that mean business.
Best for: Growing retailers, multi-site businesses, and anyone who needs a reliable, feature-rich epos system.

| Feature | SumUp | Shopify POS | Epos Now |

What About Restaurants and Cafes?
While we've focused on retail, many of you might be running a hybrid business: maybe a bookshop with a coffee corner.
In those cases, you might want to look at a restaurant pos system. Systems like Toast POS are fantastic for hospitality, but for most general retailers, Epos Now is often the better shout because it handles physical stock and barcodes much more effectively. You can read more about Toast EPOS for restaurants if you think your business leans more towards food and drink.
How to Make the Final Call
Choosing the right system is a big deal, but it doesn't have to be overwhelming. We always recommend following these three steps:
- Count Your Products: If you have under 50 products and only sell in person, SumUp is a fantastic, low-cost way to start. It’s definitely the cheapest epos route for very small setups.
- Look at Your Website: If your online store is the heart of your business, Shopify is the logical partner.
- Think About Next Year: If you plan on opening a second location, hiring five more staff, or if you simply need a system that won't let you down when the Wi-Fi dies, then the Epos Now till system is our top recommendation.
Our Verdict
At the end of the day, your pos system should save you time, not take it away.
While SumUp is great for the budget-conscious and Shopify is perfect for the web-savvy, we find that for the majority of UK retailers, Epos Now offers the best balance of features, reliability, and support. It grows with you, which means you won't have to go through the headache of switching systems in two years' time.
It’s definitely worth getting a demo to see how it looks in action. You can find more information and see if they have any current offers by visiting our full Epos Now review page.
