SumUp vs Zettle: Which is better for taking payments?

Based on findings from our impartial team of researchers, we can declare that, when it comes to the best free POS system, SumUp wins out between SumUp and Zettle. Our latest research from May 2025 found that SumUp comes with more advanced software features, and a better range of terminals and accessories – just giving it the edge over Zettle.

While SumUp might be the victor, it’s a close-run race, and both systems have strengths and weaknesses you’ll need to know about before choosing one. We’ll take you through a round-by-round breakdown in the areas that are most crucial to a successful retail or hospitality business.

Which is cheaper?

Zettle’s pricing is straightforward and simple. It charges a flat 1.75% transaction fee, which is roughly about average compared to its competitors, making for a pretty great deal considering you’re getting it on Zettle’s free plan.

SumUp also offers a free plan, and its transaction fee of 1.69% for in-person payments is cheaper than Zettle’s 1.75%. But if you pay for its Payments Plus plan, you’ll be only be charged  a rock bottom 0.99% transaction fee. And, at £25 plus VAT, SumUp’s card reader is about half the cost of the Zettle Reader 2, which is £49 plus VAT.

SumUp’s free POS plan will get you access to basic capabilities, such as:

• Taking card and digital payments
• Tracking your sales
• Creating invoices
• Managing tips.

To access the full range of extensive features you’ll need to pay for SumUp POS Pro, which costs £49 per month. There’s also additional costs for certain features, including stock and ingredient management, so new starters need to bear this in mind.

While SumUp might be a nose ahead, ultimately both systems are very reasonably priced. For those who need to get set up on a budget and don’t want to be locked down into a contract, both are fantastic options.

Which is easier to use?

Since our previous testing in 2024, Zettle has remained a consistently easy-to-use system. It’s equally intuitive in both the front and back ends of the software. The stripped down minimalism of the menus and the large clear buttons really stand out as key design strengths.

While we did experience a few crashes and bugs, and a few issues persist into 2025 (like the lack of a search function on the item screen when using an iPad) we appreciated Zettle’s simplicity. The intuitive system would be a good fit for pop-ups, cafes or businesses on the move, like food trucks.

Meanwhile, SumUp has made some notable changes to its front end since 2024, but we still found the back office could be clunky, slow to load, and didn’t always synchronise perfectly with the front end. There are a few missing hospitality POS system features, like bill splitting.

However, the front end has seen improvement, especially when completing core tasks like table management, editing an order, or cancelling a payment. It would be a good beginner-friendly software, thanks to the easy navigation and short learning curve.

It was a close call between the two platforms, as both excel in simplicity and ease of use (although Square beats them both as the most user-friendly POS platform for retail businesses, as well hospitality). However, we felt there was less of a disparity between the front and back office with Zettle’s interface, which just put it past the post for us.

Both of these systems’ free plans come with some handy features included straight out the box, such as:

• Gift card creation
• Tap to Pay on phone
• Sales reports

However, SumUp is able to provide a more advanced set of tools with its Plus and Pro plans. On SumUp’s Plus plan, you can get table management features, a real-time overview of your cash flow, and you can assign a printer to the bar or kitchen.

SumUp POS Pro, the top tier, provides advanced employee management, inventory tools, and multi-store support. You can also set up and customise mobile and QR code ordering, which could be essential for businesses that need a takeaway POS system, or events-based companies.

During our testing, we particularly appreciated:

• SumUp’s personalised loyalty programme that helps you drive repeat business (though this is a paid extra)
• The ingredient tracking feature
• The customisable kitchen display interface (subject to a monthly cost)
• Its built-in email marketing

Zettle offers some solid software as well, impressing us with how quick it is to add products and apply discounts. However, we did find it lacked the more advanced tools needed by bigger retail stores.

Zettle’s deficit of in-depth cost vs profit management tools would also be an issue for larger scale businesses, while the lack of built-in floor planning functionality will also rule it out for some restaurateurs.

That said, we did appreciate:

• The customisable gift card features, including the option to sell and accept physical gift cards
• Zettle’s customer loyalty programme, which is included as a free add-on

If you run a small, single-store retail or cafe business and only have a handful of items to sell, Zettle’s free software is still a very strong option for you. But it’s the depth of tools and features provided by SumUp’s Plus and Pro plans that seal the deal for us this round.

How does their point of sale hardware compare?

Zettle provides the small, lightweight, Zettle Reader 2 card machine and the PayPal Terminal, a handheld touchscreen POS terminal and card machine. The POS software can also be used on an iPad – in fact, Zettle is one of our top choices for an iPad-based POS. Zettle also provides a selection of’ ‘ready-made’ store kits that combine different hardware and accessories.

SumUp provides an impressive range of hardware. We really like the small and sleek SumUp Air card reader, and when we recently tested out the POS Lite countertop terminal (comprised of a tablet and stand), we were impressed by how sleek and professional it felt, while still remaining lightweight and affordable.

The POS Lite connects to the card reader, and has a 13” HD screen which SumUp claims is ‘splashproof’ (good if you’re looking for a POS system for bars that can stand up to hectic happy hours), and comes pre-installed with the free version of the software.

With SumUp’s POS Pro plan, you can choose one of its card readers – either the SumUp Air or the SumUp Solo – which then connects to an iPad (which can be displayed on a stand to create a countertop terminal). You’ll also have the option to add on a separate kitchen display (a Lenovo 10” tablet).

What is their user support like?

Both SumUp and Zettle offer a wide range of user support channels – including phone lines, email, live chat, in-platform support, and video tutorials – though, unlike SumUp, Zettle also provides support on social media.

This might have given Zettle the edge over SumUp, but when putting the knowledge centres through their paces, we found that SumUp’s performed slightly better.

That said, when we tested the chat functions of both platforms (we asked them “How can I view my sales and revenue reports?”) we found the speed and accuracy of the answers were identical – despite Zettle’s chat being answered by an actual human, whereas SumUp’s was just a bot.

What did finally push SumUp onto the winners podium, though, was the fact that, unlike Zettle, it offers a training mode for onboarding new staff.

SumUp vs Zettle: the overall verdict

This was a close call, as both POS providers were often neck and neck, with comparable pros and cons.

But ultimately, SumUp’s scalability and wider range of hardware make it the stronger option of the two. In particular, we feel that SumUps’ POS Pro, while expensive, will offer more bang for your buck if you run a small to medium-sized retail business, or if you’re running a cafe or small restaurant.

Zettle is still a very strong low-cost option, though. Zettle’s iPad-based free plan is great for ventures with smaller budgets, such as mobile businesses and pop-ups, as you can get started with it for very little investment.

Methodology: how we put SumUp and Zettle to the test

In our latest round of POS research conducted in May 2025, our Senior Research Executive evaluated a total of 11 systems, including SumUp and Zettle, in order to ensure our recommendations and insights are up to date and accurate.

Both of these systems were then tested by our dedicated Reviews Writer alongside other testers in our Startups offices in London, evaluating both the front and back ends of the platforms. This was set against a review framework devised by our Head of Research and Senior Research Executive.

In order to put Zettle and SumUp head to head, we compared them on the five categories we determined as the most important for POS users:

• Price: are you getting good value for money? We compare upfront costs, transaction fees, monthly costs, and whether a free trial is offered.
• Hardware: we examine the range of card readers, terminals and accessories that are offered by the provider.
• Software: we analyse the depth and range of features provided, including inventory management, reporting and analytics, employee management and more.
• Help and support: we look at the range and accuracy of the help and support options available.
• Usability: we test how easy to use the system is, on both the front end and back office.

As POS systems are needed across different industries, we determined two different testing groups for SumUp and Zettle: one specifically for their retail features, and one for the features that serve the hospitality industry. We were then able to cover the most important results from each group in this article, so that we can help you make a choice, whichever industry you’re in.
