When you’re first starting a business in the UK, your to-do list is likely as long as your arm, and your budget? Well, it’s probably tighter than a new pair of shoes. It’s only natural that you’d go searching for the cheapest pos system you can find. After all, why pay hundreds of pounds a month when you can get a card reader for the price of a fancy lunch?
But here’s the million-pound question: can a budget-friendly pos system actually help you scale, or will it become a bottleneck that holds your business back just as things start getting exciting?
At What EPOS, we’ve seen plenty of entrepreneurs start with a basic setup, only to realise six months later that they’re drowning in manual admin because their "cheap" system doesn't talk to their accounting software or manage inventory properly. On the other hand, some of the top entry-level systems have evolved massively in recent years.
Today, we’re diving into the UK’s top 3 "budget" contenders to see if they’ve got the legs for the long run, and we’ll look at why a slightly more robust epos system might actually save you more money as you grow.
1. SumUp: The King of Simplicity
If you’ve ever bought a coffee from a pop-up stall or a burger from a food truck, you’ve almost certainly seen a SumUp POS in action. It’s often the first port of call for UK micro-businesses because the barrier to entry is practically non-existent.
The Pricing
SumUp is famous for its "no monthly subscription" model. You buy the hardware (often starting as low as £39 for their basic reader) and pay a flat transaction fee of 1.69%. For a small business doing a few thousand pounds a month, this is incredibly attractive. There’s no pressure to meet monthly targets, and if you have a slow week, it costs you nothing.
Can it scale?
In terms of pure hardware, SumUp has expanded its range to include the "Solo" and the "POS Lite," which feels more like a traditional retail pos system. However, while it’s great for taking payments, the back-end reporting is relatively basic.
If you’re planning to open a second location or you have a complex menu with hundreds of modifiers, you might find SumUp a bit limiting. It’s an excellent starting point, but if your goal is to become a high-street staple, you might find yourself looking for something with more "oomph" sooner than you think. You can read more about its features in our SumUp POS system review.
2. Zettle (by PayPal): The All-Rounder
Zettle (formerly iZettle) is another heavyweight in the budget category. Since being acquired by PayPal, it has integrated even more deeply with online payment ecosystems, making it a strong contender for businesses that sell both in-person and online.
The Pricing
Similar to SumUp, Zettle offers a free version of its pos system software. You pay for the hardware (their card reader is often discounted for new customers) and a transaction fee of 1.75%. Interestingly, Zettle offers custom rates for businesses processing over £10,000 a month, which is a nod toward their ability to handle scaling businesses.
Can it scale?
Zettle’s app is slick and user-friendly. It handles inventory better than most "free" systems and integrates well with accounting software like Xero and QuickBooks. For many small boutiques or cafes, Zettle provides enough "runway" to grow significantly. However, once you start needing advanced features like table management for a busy restaurant pos system or sophisticated employee permission levels, the cracks can start to show.
3. Square: The Feature-Packed Powerhouse
Square changed the game when it landed in the UK. While it’s often grouped with the "cheap" systems because of its low entry cost, the software itself is surprisingly sophisticated.
The Pricing
Square offers a free software tier that is remarkably feature-rich. Like Zettle, you pay a 1.75% transaction fee for chip and pin payments. Where Square stands out is its industry-specific versions. They offer dedicated versions for retail and restaurants, some of which have free tiers and others that carry a monthly fee for advanced features.
Can it scale?
Square is probably the most "scalable" of the budget-friendly options. It offers everything from simple card readers to the Square Register, a fully integrated dual-screen epos system. Because they offer features like online ordering and loyalty programmes built-in, you can add these services as your business grows without switching providers.
That said, as your volume increases, those 1.75% transaction fees can start to look quite expensive compared to the wholesale rates you can get with a more traditional merchant account and a dedicated system like the Epos Now till system.
The Hidden Cost of "Cheap"
It’s easy to focus on the upfront cost of the hardware, but as a business owner, you need to look at the Total Cost of Ownership (TCO). A system that costs £0 per month but charges 1.75% on every sale might be much more expensive than a system that costs £25 a month but offers a lower transaction rate.
According to data from the British Retail Consortium, payment costs are a significant concern for UK retailers, and finding the right balance between software fees and transaction rates is key to maintaining healthy margins.
When you scale, you also need to consider:
- Inventory Management: Can the system handle thousands of SKUs without lagging?
- Reporting: Can you see which products are most profitable across multiple locations?
- Integrations: Does it work with your CRM, your website, and your delivery apps (like Deliveroo or UberEats)?
This is where systems like Shopify POS come into play for retailers who are serious about omnichannel growth. You can check out our Shopify POS review to see how it compares for growing brands.
Why Epos Now is the Smart Choice for Scaling
While SumUp, Zettle, and Square are fantastic for getting off the ground, if your plan is to build a serious business, you should strongly consider starting with, or moving to, a dedicated epos system like Epos Now.
We often recommend Epos Now because it bridges the gap between "affordable" and "enterprise-level." It’s designed specifically for the UK market and offers specialized software for both retail and hospitality sectors.
The Benefits of Choosing a Specialist
Unlike the "one-size-fits-all" approach of some budget card readers, an Epos Now till system provides:
- Scalability: Whether you have one shop or fifty, the system grows with you.
- Robust Hardware: Their tills are built for the rigours of a busy retail or restaurant environment, no more worrying about an iPad battery dying mid-shift.
- Advanced Reporting: Deep insights into your business that help you make data-driven decisions.
- 24/7 Support: When your system goes down on a busy Saturday night, you need more than a chatbot; you need an expert on the phone.

Our Verdict: Can You Scale with the Cheapest?
The short answer is: yes, but only to a point.
If you are a sole trader, a market stall owner, or you’re testing a new concept, starting with a sumup pos or Zettle is a brilliant, low-risk way to get moving. These systems have democratized payments and made it possible for anyone to start a business.
However, if you have ambitions to hire staff, open multiple sites, or manage a complex inventory, the best pos system for you isn't necessarily the cheapest one today: it’s the one that provides the best value over the next three years.
Scaling a business is hard enough without having to fight your software. Transitioning to a professional system like the epos now till system early on can save you the massive headache of migrating your data later. It gives you the professional tools you need to manage staff, delight customers, and ultimately, stay profitable.
Ready to find the perfect fit for your business? Don't just settle for the lowest price; look for the best partner for your growth. We highly recommend checking out our comprehensive Epos Now review to see why it’s a top choice for thousands of UK business owners who are serious about scaling.
Choosing an epos system is a big decision, but it doesn't have to be overwhelming.

Whether that's the simplicity of a card reader or the power of a full Epos Now setup, the right choice is the one that lets you focus on what you do best: running your business.
