Let's be honest, choosing a POS system isn't just about fancy features or sleek interfaces. At the end of the day, you're running a business, and every pound matters. Whether you're opening a coffee shop, launching a restaurant, or running a retail store, the wrong POS choice can quietly drain your profits month after month.
We've taken a deep dive into three popular systems, SumUp, Toast, and EPOS Now, to figure out which one actually delivers the best value for your money. Spoiler alert: the answer isn't the same for everyone, and it definitely depends on what kind of business you're running.
The Quick Cost Overview
Before we get into the nitty-gritty, here's the bird's-eye view of what you're looking at with each system.
SumUp is the budget champion if you want simple, pay-as-you-go pricing. There's no monthly fee for the card reader, and you'll pay around 2.75% per transaction for in-person payments. It's dead simple and transparent, which is refreshing when most companies hide fees in the small print.
Toast is purpose-built for restaurants and comes with premium pricing to match. They don't advertise their costs upfront (always a red flag), but the trade-off is you're getting specialized features that generic systems just can't match. If you're running a full-service restaurant, those features might justify the higher price tag.
EPOS Now takes a different approach with an upfront payment model rather than endless monthly subscriptions. You'll pay more initially, but it can work out cheaper over time, especially if you're planning to stick with your system for years rather than months. See our full EPOS Now breakdown here.
Breaking Down the Real Costs
Here's where things get interesting. The advertised price is never the full story.
SumUp: The Straightforward Option
SumUp wins points for transparency. What you see is what you get, no hidden monthly fees lurking around the corner. The 2.75% transaction rate is competitive, especially for smaller businesses processing modest volumes.
The catch? While the card reader is affordable, the actual POS software doesn't have a free tier like some competitors. If you need proper inventory management or employee tracking, you'll need to pay for their Plus plan. For a market stall or mobile business, though, you might not need those extras anyway.
Toast: The Restaurant Specialist
Toast doesn't publicly list its pricing, which immediately makes it harder to compare. From what we've gathered, it's positioned as a premium option specifically for the restaurant trade. You're paying for things like table management, kitchen display systems, and menu engineering tools that other systems simply don't offer.
If you're running a busy restaurant with complex needs, Toast's specialized features could actually save you money by improving efficiency. But if you're a café or small eatery, you might be paying for bells and whistles you'll never use.

EPOS Now: The Middle Ground with a Twist
EPOS Now's upfront payment model is unusual in the POS world, where monthly subscriptions are the norm. You'll pay more at the start, but you're essentially buying the system rather than renting it forever.
The optional fees for advanced reporting and certain integrations can add up, so you'll want to think carefully about which features you actually need. That said, the system is genuinely powerful once you've unlocked those extras, it's designed for businesses that are scaling up rather than staying small. If you're serious about growth, EPOS Now's integration options might be exactly what you need.
Which System Saves You Money Based on Your Business?
This is where the "best value" question gets complicated. The cheapest option isn't always the one that saves you the most money in the long run.
For Small, Mobile, or Pop-Up Businesses
If you're running a market stall, food truck, or pop-up shop, SumUp is probably your best bet. The low barrier to entry and simple pricing make it ideal when you're just starting out or keeping things lean. You won't get loads of fancy features, but you also won't be locked into expensive contracts.
For Independent Retailers
Retail businesses need solid inventory management, and this is where SumUp starts to show its limitations. You'll quickly outgrow the basic features if you're stocking hundreds of products or managing multiple staff members.
EPOS Now makes more sense here. Yes, the upfront cost is higher, but the system can actually handle proper retail operations without falling over. The inventory tracking, staff management, and reporting tools are built for businesses that need more than just a card reader. Our detailed EPOS Now review covers why it's particularly strong for retail.
For Restaurants and Cafés
This is where Toast really shines: if you can afford it. The restaurant-specific features like split billing, course timing, and kitchen communication can genuinely improve your service and reduce errors. Those improvements translate directly to happier customers and fewer wasted orders.
That said, if you're running a smaller café or casual dining spot, Toast might be overkill. EPOS Now offers solid restaurant functionality at a lower price point, though it lacks some of Toast's more advanced features. Check out our Toast review and SumUp review to see how they stack up for foodservice.
The Hidden Costs Nobody Tells You About
Here's what the sales brochures don't mention clearly enough:
Transaction fees add up fast. If you're processing £50,000 a year through SumUp at 2.75%, that's £1,375 in fees annually. Toast and EPOS Now may have different structures, but the principle is the same: high volume means high fees.
Hardware breaks. Card readers, receipt printers, and tablets don't last forever. SumUp's readers are fairly cheap to replace, but Toast and EPOS Now hardware can cost significantly more. Factor in replacement costs when you're budgeting.
Integrations aren't always free. Want to connect your POS to your accounting software or online ordering platform? Some systems charge extra for those integrations. EPOS Now, in particular, has optional fees for certain advanced integrations, though they're transparent about it.
Support matters more than you think. When your till stops working on a busy Saturday afternoon, you need help now. The quality of customer support varies wildly between systems, and it's worth paying a bit more for reliable assistance. EPOS Now's UK-based support team is genuinely helpful, which can save you both time and stress.
Our Honest Verdict
So which system actually saves you money? It depends entirely on your situation.
Choose SumUp if: You're just starting out, keeping things simple, or operating a mobile/pop-up business. The low costs and easy setup make it perfect for testing the waters without a massive commitment.
Choose Toast if: You're running a proper restaurant with complex needs, and you need specialized features that justify the premium pricing. The investment makes sense if those tools genuinely improve your operations.
Choose EPOS Now if: You're serious about building a sustainable business and want a system that can grow with you. The upfront cost might sting, but the long-term value is solid: especially for retail or hospitality businesses that need more than basic features. The UK-based support and robust integrations make it a safe choice for businesses that can't afford downtime.
If we're being completely honest, EPOS Now offers the best balance of cost and functionality for most growing businesses. It's not the cheapest upfront, but it's built to last and won't force you to upgrade or switch systems as you scale. The real savings come from efficiency gains and avoiding the hassle of outgrowing your POS system within a year.
Making Your Decision
Don't just look at the sticker price. Think about your transaction volume, how many features you'll actually use, and what kind of support you'll need when things go wrong (because they will).
