Or will Zettle prove that sum card readers are just better than others?SumUp and Zettle (formerly iZettle, prior to its acquisition by PayPal) both offer affordable, flexible solutions for merchants looking to accept credit and debit card payments. Which – right now, especially – is just about all businesses!Small card readers, big names. But which of the two is right for you?We wanted to find out. So, we compared the two companies – known in the industry as payment facilitators – across the metrics that are important to UK businesses. Read on to compare SumUp and Zettle’s card readers, ecommerce services, rates, customer support, and reviews.Or, if you’re on the verge of a purchase, and you just need to know which one is better – right now! – we’ve summarised our research here for you. SumUp vs Zettle: At a glanceSumUp wins. It has better customer support, more favourable customer reviews, and lower processing fees. According to our research, it’s also an easier option for creating – and selling through – an online store.There’s also the issue of Zettle’s acquisition by PayPal, which has (understandably) shaken things up a bit in terms of what services Zettle will continue to offer. Going forward, we tip Zettle to make a comeback. But given the company’s current teething problems, we’d recommend that new merchants make SumUp their selection – for now, at least! Card readersWe put SumUp’s flagship card reader – the SumUp Air – head to head against its Zettle counterpart, the 2.As you can see below, the results are… inconclusive.SumUp AirZettle 2£29 (excl. VAT)£29 (excl. VAT)Accepts all major card typesAccepts all major card types12-month warranty12-month warrantyBoth card readers come with a 12-month warranty and free app. This app uses a Bluetooth connection to connect your card reader to your tablet or smartphone – from which you ring up transactions, and manage stock and sales.Each card reader comes with a 12-month warranty, and both require either a wifi or 4G connection to operate.Only SumUp, though, offers more than one variety of card reader.And, if you don’t run your business from a fixed premises – or you rely on taking payments from more remote locations – you’ll want to forgo the Air, and opt for SumUp’s 3G card reader instead. As the name suggests, this savvy piece of tech comes with an in-built SIM card. That means you won’t have to connect it to wifi, or even your own mobile data – so it’s the perfect companion for travelling businesses, such as market stall owners, or tradespeople.Put simply, it’s one of the best credit card machines for small businesses out there. You can own it for a single, one-off cost of £99 (excl. VAT), and there’s also an option to buy it in a bundle with a receipt printer for £119 excl. VAT (discounted from £149 at the time of writing). Winner: SumUp. Variety is the spice of life, and SumUp offers more card readers, to suit a wider variety of business owners and niches.Plus, SumUp’s 3G card reader – with its unlimited supply of free mobile data, and up to 50 transactions off a single charge – is one of the finest pieces of small business payment technology on the market. Ecommerce servicesBoth SumUp and Zettle provide merchants with a range of ways to take payments without even having to use a card reader.Ideal for ecommerce businesses (or those that have had to become ecommerce businesses as a result of the COVID-19 pandemic!), SumUp and Zettle both offer up a variety of online payment methods.But who’s doing it better? Online paymentsThis one’s simple – how easy is it to sell online with SumUp or Zettle?As it turns out, very easy – although SumUp still has the edge over Zettle here.With ‘SumUp Online Store’, you can create an online shop via the SumUp app in a matter of minutes. Adding your products is simple, as is setting up shipping details, and linking your shop to whatever social media platforms your business uses.It’s free to do, and will cost you just 2.5% of each transaction you take through the store.Setting up your online shop with Zettle, however, requires integration with third-party ecommerce platform provider Selz. While the kind of online shop you can create with Zettle (via Selz) is both pristine and professional-looking, we found it a little less intuitive than with SumUp – in part, because it’s not all possible through a single app.Verdict? If selling online is on your mind, pick SumUp. Payment linksBoth SumUp and Zettle allow you to send payment links to your customers, from directly within their respective apps. Whichever option you choose, it’ll cost you 2.5% of the transaction’s value. Virtual terminal transactionsVirtual terminals are web-based portals via which you login, enter your customer’s card details (typically as they're reading them to you over the phone, to maintain PCI compliance), and take payment.It’s a super convenient way to get paid – particularly if you work from home on a permanent basis, or lack the tools or time to set up a proper website.Better still, SumUp’s virtual terminal is extremely easy to use. You just log in with the app, or access it via SumUp’s online dashboard from your computer. SumUp’s virtual terminal costs 2.5% per sale you make through it.Zettle doesn’t offer a virtual terminal service – though, with the PayPal acquisition continuing to effect seismic changes on how Zettle goes about its business, it’s worth watching this space! Did You Know? Virtual terminals are the UK payment industry’s best-kept secret. But how can they benefit your business, and who are the top suppliers?Learn more about the UK’s best virtual terminals with our 2021 guide. PayPal QR code paymentsSpeaking of changes, Zettle has recently introduced an option that allows its merchants to accept PayPal-generated QR codes as payment. While that’s good news for PayPal users, it’s even better news for Zettle merchants, who – for the time being, at least – will pay a fee of just 1% per transaction to accept these types of payment.For obvious reasons, this deal doesn’t also apply to SumUp merchants!Read more: The Best Merchant Account Providers for Ecommerce in 2021 Winner: SumUp. Zettle's lack of a virtual terminal, plus its slightly tricker pathway to setting up an ecommerce store, means that – even with its new-fangled QR codes – it doesn't quite compete with SumUp in this area. PriceBoth SumUp and Zettle are well-known for (heck, have built their reputations around) their low fees. But since we’re splitting hairs, SumUp is the cheaper of the two, with a card-present rate of just 1.69% per transaction. Zettle’s rate for the same type of sale is 1.75%.For the card readers themselves – which is a single, one-off fee, rather than an ongoing cost – there’s no separating the two. Both the SumUp Air and the Zettle 2 devices cost £29 (excl. VAT) a pop. Each provider’s charging stand – which SumUp calls the ‘cradle’, and Zettle the ‘dock’ – costs £39 (excl. VAT), so there’s nothing to choose between there, either.For card-not-present sales, it’s the same story – you’ll pay 2.5% per each sale you take via invoicing or through a payment link, whether you use SumUp or Zettle.A close one, then – but SumUp’s low processing fees mean it shades this one. Winner: SumUp…. just!If interpreting these costs has your head spinning, don’t fret – we get it.

POS (point of sale) equipment and appsIf you take payments on the go, your nifty new card reader – whether it’s from SumUp or Zettle – will be enough.If you do most of your business over the counter, though, that card machine is going to start looking lonely. Pretty soon, you’re going to want to see what kind of value POS equipment can add to your bricks and mortar setup.The good news is that both SumUp and Zettle integrate with some of the best EPOS providers in the space, such as Lightspeed and Vend. Where Zettle steals a march on its opponent, though, is that it allows you to purchase a wider range of additional equipment to get your counter singing.These include:Receipt printersSocial distancing screensBarcode scannersCash drawersThe better news for SumUp fans, though, is that its acquisition of London-based POS provider Goodtill (which was finalised in November 2020) means that the breadth of its POS offerings is only likely to improve and expand going forward.Additionally, both SumUp and Zettle offer a monthly subscription for bricks and mortar businesses – though in practice, they’re best-suited to those in the hospitality industry. Let’s take a look at how they compare. Goodtill by SumUp With intuitive, intelligent options for stock and waste management – plus tools for discounting and customer loyalty tracking – SumUp’s monthly POS subscription offers benefits both at the front and the back of house.Reporting capabilities are included as standard, and your staff will be able to clock in and out with ease.

VAT) – a timely innovation that’s sure to add peace of mind to staff and customers alike. Customer supportWhen it comes to collecting money for your goods or services, you can’t afford to waste time if you run into an issue. Having customer support available when you need it is crucial – so which provider does it better?We took a couple of factors into account to find out. One’s the level of phone support available, and the other is the overall level of customer satisfaction online.It’s SumUp vs Zettle, going another round. Who are you putting your money on? Phone supportWhen it comes to quality phone support, SumUp comes out on top. Its contact centre is open Monday to Saturday, and there’s someone to chat to 64 hours of the week. Support from Zettle, by contrast, comes in at 40 hours a week – its contact centre is only open between 9am and 5pm Monday to Friday. Customer satisfaction levelsSumUp is the more favourably reviewed provider of the two. Boasting a Trustpilot score of 4.3/5 from 2,699 reviews (at the time of writing), SumUp trumps its Zettle’s 3.9/5 rating (from 2,758 reviews) with ease.We grabbed a couple of recent reviews of each provider to see what Sumup and Zettle’s customers are saying. “I’ve used SumUp for four years now, and [its support team] is effortless to deal with – always helpful, and solves the odd query or problem almost instantly.

It's always been quick and reliable until the last couple of months – now, it seems to take an eternity to process a payment, and continually loses the Bluetooth connection between my tablet and the card machine.“I'm not doing anything different. But, despite trying everything, the problem persists. Please fix it so I can go back to five stars for my review!”Blackhall Late Store, Zettle customer, 1st March 2021 “I recently swapped my business from another supplier to Zettle, and I can honestly say that it’s been a breath of fresh air! Zettle is slightly more expensive, but I’ve experienced good service so far. It’s also quick and easy to set up.”Matt, Zettle customer, 3rd February 2021We should note here that some of Zettle’s most recent reviews have criticised what they perceive as the negative effects of the company’s acquisition by PayPal. These include the discontinuation or changing of services, slower processing times, connectivity issues, and a loss of Zettle’s original ‘small business’ ethos and focus.We unpack all this and more in our Zettle review, written for 2021.
