Let’s be honest for a second: trying to find the right epos system feels a bit like trying to solve a Rubik's Cube in the dark. You see a flashy ad promising a "free" or "cheap" setup, only to find out six months later that your bank account is leaking money faster than a cracked pipe.
We’ve spent a lot of time looking at the numbers, and the truth is that the "sticker price" of a pos system is rarely what you actually end up paying. If you’re a small business owner in the UK, you’re likely looking for the best pos system to help you grow, not one that’s going to nickel and dime you into early retirement.
In this guide, we’re going to pull back the curtain on the industry. We’ll look at the hidden costs, the "optional" extras that aren't actually optional, and how you can find the cheapest pos system that actually delivers on its promises.
The Software Subscription Trap: Why £29 Isn't Always £29
When you’re browsing for a new retail pos system or a restaurant pos system, you’ll see prices like £29 or £39 per month everywhere. It sounds reasonable, right? It’s about the price of a couple of pizzas.
However, many providers use a "tiered" system. That basic price often gets you the bare bones. If you want to track inventory properly, manage staff rotas, or integrate with your accounting software, you’ll suddenly find yourself bumped up to the "Pro" or "Enterprise" tier. Before you know it, that £29 has ballooned into £100+ per month.
We’ve found that some brands are more transparent than others. For example, the Epos Now till system is quite popular because they offer a clear path on what you’re paying for. But even then, you need to keep your eyes peeled for those "add-on" modules.

Payment Processing: The Real Money Maker
This is the big secret that most "experts" don't want to shout about. For most providers, the software subscription is just the bait; the payment processing is the hook.
Payment processing fees are typically the largest ongoing expense for any business. You’ll usually see rates ranging from 1.5% to 2.9% for card-present transactions. While SumUp POS is great for its simplicity and lack of monthly fees, their transaction rates are often higher than a dedicated contract system.
On the other hand, if you look at something like Toast POS or Shopify POS, they often require you to use their in-house payment processor. If you try to use your own bank, they might charge you a "transaction fee penalty."
The Hidden Costs of Processing:
- The "Plus" Fee: You might see a rate like 2.6% + 10p. That 10p sounds small, but if you run a coffee shop selling £3 lattes, that fixed fee is eating a massive chunk of your margin.
- Keyed-in Rates: If you ever have to type a card number in manually, expect the rate to jump significantly.
- International Cards: Taking a payment from a tourist? You’ll likely pay an extra 1% or more for the privilege.
Hardware: The "Free" Equipment Illusion
We all love a bargain, and seeing "Free Hardware" in a headline is incredibly tempting. But as we always say, nothing in life is truly free.
Usually, "free" hardware comes with a much longer contract (sometimes 3 to 5 years) and higher monthly software or processing fees. If you decide to leave early, you might find yourself hit with a massive exit fee or a bill for the full "market value" of that hardware.
If you’re looking for a retail pos system, we often suggest buying your hardware upfront if you have the capital. It gives you more leverage to switch providers later if their service goes downhill.
The Maintenance and Support "Sneak"
Imagine it’s a busy Friday night, your restaurant pos system crashes, and you can’t take orders. You call support, only to be told that "Premium Support" is an extra £15 a month, and without it, you’ll have to wait 48 hours for an email response.
This happens more often than you’d think. Some companies charge for:
- Phone support: Only allowing email/chat on basic plans.
- Software updates: Charging a "maintenance fee" to keep your system running smoothly.
- Cloud backups: Ensuring your data isn't lost if the hardware breaks.
When we reviewed the epos now till system, we noticed they offer various levels of support, and it’s definitely worth checking if the support you need is included in your monthly quote. You can read our full Epos Now review here to see how their support tiers actually work.

PCI Compliance and Gateway Fees
These are the "boring" fees that people forget to ask about. PCI DSS (Payment Card Industry Data Security Standard) is a set of security standards designed to ensure that all companies that accept, process, store or transmit credit card information maintain a secure environment.
Some providers include this in your monthly fee. Others will tack on a £5–£30 monthly "compliance fee." Then there are "Gateway Fees," which is basically a charge for the digital pipe that sends your payment data to the bank. It’s another £10–£20 that can sneak onto your bill.
Comparing the Big Names: SumUp, Shopify, and Toast
If you’re searching for the best pos system, you’ve likely come across these three.
- SumUp POS: Fantastic for micro-businesses or pop-up shops. There are no monthly fees, which is great for the "cheapest pos system" crown if your volume is low. But as you grow, those transaction fees will start to hurt.
- Shopify POS: The gold standard if you also sell online. It syncs perfectly. However, the monthly costs can escalate quickly if you need the "Pro" features for your physical shop.
- Toast POS: Specifically built as a restaurant pos system. It’s incredibly powerful, but their hardware and processing can be on the pricier side.
How to Find the Right Balance
So, how do you avoid these traps? It’s all about doing the math for your specific volume.
- Estimate your monthly card turnover: If you’re doing £20k a month, a 0.5% difference in processing fees is £100. That’s more than the cost of most software!
- Ask for a "Total Cost of Ownership" (TCO) for 3 years: Include hardware, software, processing, and all those sneaky compliance fees.
- Negotiate: Especially if you’re an established business with a high turnover. Most EPOS companies have "room" to move on their processing rates.
We’ve found that for many UK businesses, the epos now till system offers one of the most balanced packages. They have a massive range of integrations (like Xero and Sage) and provide hardware that’s built to last in a tough retail or hospitality environment.
If you want to see exactly how their pricing stacks up and if it’s the right fit for your shop or restaurant, we’ve put together a very detailed guide. You can check out our Epos Now till system review to see the pros, cons, and the real costs involved.

The "Secret" to Staying Profitable
The real secret isn't just finding the lowest price: it's finding the system that saves you time. If a "cheap" system takes you an extra 5 hours a week to manage your inventory because the software is clunky, you haven't saved money. You've just bought yourself a second job.
A good epos system should be an invisible partner. It should handle your taxes, manage your stock levels, and tell you which products are making you money and which are just gathering dust.
Quick Checklist Before You Sign:
- Is the processing rate fixed or "interchange plus"? (Interchange plus is usually better).
- What happens to the hardware if I cancel?
- Is 24/7 phone support included?
- Are there any "integration fees" to link my accounting software?
- Can I use my own payment processor if I find a better deal?
Final Thoughts
The EPOS industry is competitive, and that’s a good thing for you. It means you have choices. Whether you go with Shopify POS for your boutique, Toast POS for your bistro, or the versatile Epos Now for your high-street shop, just make sure you’re looking at the big picture.
Don't let a low monthly software fee blind you to high transaction costs. Take your time, ask the hard questions, and always read the fine print.
If you're still feeling a bit overwhelmed, we highly recommend starting with our Epos Now review. It’s a great benchmark to compare other systems against and will give you a solid idea of what a professional setup should actually cost.
Good luck with your search: getting your EPOS right is one of the best things you can do for your business's future!
