Zettle and SumUp have many similarities, but over the last few years, they’ve been branching out their products in different directions.

What they’re best known for in the UK is their two mobile card readers: Zettle Reader and SumUp Air. These pocket-sized terminals cost less than £40 each and work in conjunction with a smartphone or tablet app, making them super-accessible for any small business.

What other things do they have for small businesses? And how do SumUp and Zettle compare in general? Let’s have a closer look.

Card machines: different looks, similar types

You’ve probably seen Zettle Reader (previously called iZettle Reader) in cafés, small shops or at the hairdressers – if not that, then the SumUp Air.

Both connect to an iPad, iPhone or Android tablet or smartphone via Bluetooth with the associated payment app. Transactions happen over the internet, using the mobile device’s 3G/4G network or WiFi. What’s more, the app works like a till with a product library and other features to form a complete point of sale (POS) system.

In addition, SumUp also offers a pocket-sized terminal called SumUp Solo. This model works with WiFi, or a 4G/3G connection through a SIM card with unlimited, free data. SumUp Solo is completely independent, so a linked mobile device is not required.

The Solo and Printer package includes the same SumUp Solo reader as mentioned, plus a printing-and-charging cradle that’s portable.

Zettle has its own standalone card machine: Zettle Terminal. It looks a lot like a smartphone with its large touchscreen and same shape and size as an average iPhone, but it can be purchased with a receipt printer-and-charging dock and/or a version with a barcode scanner built in. It has Zettle’s till app installed and accepts chip and PIN or contactless payments with WiFi or a mobile connection (SIM card included).

An interesting features both companies added recently is Tap to Pay on iPhone/Android. Basically, it allows merchants with an NFC-enabled smartphone to accept contactless card or mobile wallet transactions directly on their phone – without any of the above card readers.

Still, I and many others prefer to accept card payments through a dedicated card reader, because it allows chip and PIN payments, and it’s not such a big deal to have a card reader stolen compared with my smartphone. The Tap to Pay option is mostly used as a backup solution.

Pay-as-you-go pricing, only small differences

Zettle’s and SumUp’s transaction fees are very similar. Zettle charges a fixed rate of 1.75% and SumUp 1.69% of all card transaction totals regardless of card brand – even when it is a premium, foreign-issued debit or credit card.

The app-based card readers are similarly priced: £29 for Zettle Reader and £49 for SumUp Air, exclusive of VAT.

SumUp Solo, on the other hand, is more expensive due to its ability to work on its own, costing £79 + VAT. If you get the SumUp Solo and Printer duo, you pay £139 + VAT.

Zettle Terminal, including the SIM card with unlimited data, costs £149 + VAT without barcode scanning or £199 + VAT if bundled with the Printer & Dock. Zettle Terminal with an inbuilt barcode scanner costs £199 + VAT on its own or £249 + VAT if bundled with the printing dock.

Low-volume merchants with card transactions of £2,000 per month will see no significant difference in fees – SumUp would charge £33.80 and Zettle £35.

For medium-volume business, these card rates are comparable with negotiated rates from Worldpay, Elavon and other providers. Zettle’s and SumUp’s rates are really competitive for premium cards like UnionPay and Amex, which normally cost significantly more in processing fees through other providers.

Neither SumUp nor Zettle have monthly fees or other charges on top of the transaction fee. You could argue that SumUp’s marginally lower card fee is compensated for through the chargeback fee, or the refund fee if processed after the transaction is cleared in your bank account.

Payouts in bank account or online account

The platforms deposit payments directly into your bank account, minus the transaction fee which is automatically deducted. Zettle’s 1-2 working days’ settlement is slightly faster than SumUp’s 1-3 working days’ bank account transfers. It depends in part on your bank how fast the deposits take.

Settlement time for SumUp depends on whether the transaction was by debit or credit card. Debit card payments are credited within a day, while credit card payments may take up to three days to show in the bank account.

Alternatively, you can access payouts the next day in a SumUp Business Account regardless of what day it is. If you accept transactions on a Saturday, for example, you can spend this money with the SumUp Mastercard (prepaid debit card) the day after, on a Sunday. There are no monthly fees for the card or transactions, or charges for transferring money from SumUp to your bank account.

To benefit from this, you need to sign up for the free SumUp Business Account, which is an e-money (online) account, not a bank account. It allows you to transfer money to UK bank accounts, take out cash at ATMs and manage your business expenses from SumUp App.

Zettle users can have their funds deposited directly in their PayPal Business account within 24 hours, but not on weekends like with SumUp Business Account.

Both accept impressive range of cards

Both Zettle and SumUp accept the most common cards including Visa, V Pay, Visa Electron, Mastercard and Maestro, plus Apple Pay and Google Play. They also allow you to take American Express, UnionPay, Diners Club, JCB and Discover at no extra cost; a bargain compared with the cost a small business would pay at a traditional merchant service provider.

The only difference between them is that Samsung Pay is also accepted by Zettle, whereas SumUp does not (at least officially) accept that.

Card reader apps comparable

Zettle Reader and SumUp Air work in conjunction with a free POS app on a mobile device (connected via Bluetooth). The software works particularly well from a tablet as a touchscreen register, but it does not work on a computer. Both apps are really user-friendly, modern and updated regularly.

The SumUp app is perfectly fine for selling simple products or services. But with Zettle Go, you have slightly more POS features like inventory tracking and barcode scanning. The register software on Zettle Terminal is almost the same as the Zettle Go app on your phone.

Gift cards, payment links, QR code payments and invoicing are included in both systems, but only SumUp allows keyed card entry at checkout.

SumUp offers the option to expand to a more comprehensive POS system called SumUp Point of Sale (previously Goodtill). This is a modular system with a core package of POS features for iPad and a choice of specialised add-on functions for retail, hospitality or online ordering.

Zettle offers no additional POS systems, but you can integrate the card reader with certain compatible EPOS.

Both systems can be expanded with accessories like a cash drawer, receipt printers and barcode scanners, suitable as a complete till system for a small brick-and-mortar shop.

Receipt printing: cheapest solution by SumUp

You’ll need a connected receipt printer to produce paper receipts, if sending digital receipts don’t quite cut it.

The easiest and best-looking solution for that is to purchase either SumUp’s Solo and printer bundle or Zettle Terminal with the printing dock.

SumUp Solo and Printer is the cheapest card terminal with a receipt printer in the UK. This is basically a SumUp Solo card reader attached to a SumUp-branded printing and charging cradle. Together, they form a very affordable, standalone card terminal that print receipts.

Go for the Solo and Printer set (left) instead of the Solo-only package (right) for paper receipts.

Zettle also has its own receipt printer, which works together with Zettle Terminal. Although Zettle’s terminal-and-printer duo is more expensive, Zettle Terminal is able to connect with Bluetooth receipt printers of other brands too, if you prefer that flexibility. In contrast, SumUp Solo only works with its own printer.

Compatible mobile or stationary receipt printers for SumUp Air include Bixolon and Star Micronics models as well as any AirPrint (iOS) or Google Cloud Print (Android) printers. Zettle Reader is compatible with various Star Micronics models, stationary or mobile, as well as AirPrint.

Distinct options for remote payments

SumUp gives you several remote payment options: Virtual Terminal for over-the-phone payments, Payment Links, email invoices and a basic online store. All but the virtual terminal cost 2.5% per transaction and can be managed through SumUp App. QR codes can also be printed and/or displayed for contactless-free payments.

You have to apply for SumUp’s virtual terminal, as it has stricter eligibility requirements. It accepts Visa, Mastercard, Maestro, American Express, Diners Club and Discover from a browser or app for 2.95% + 25p per transaction.

Although Zettle does not have a virtual terminal or online store, invoicing and payment links (charged 2.5% per payment) are available to all users.

With both SumUp and Zettle invoicing, payees can receive reminders if they haven’t paid the bill yet. Payment links do not contain customer-specific information, but are instead one-time links sent by text, email or a social media platform.

Although Zettle does not have an ecommerce store option, it can integrate with popular website platforms like Shopify, WooCommerce and BigCommerce. SumUp is reliant on its own, simple online store, mostly geared towards merchants who just need a basic website to share on social media.

Small-business reporting with some limitations

Both Zettle and SumUp give an overview of transactions in the online dashboard. There are enough reporting features to cover accounting requirements, including the ability to create reports and export sales to Excel.

Zettle has somewhat better business analytics with stock levels, most profitable days and times for certain products, discounts given, gift card tracking and more.

SumUp’s reports are more limited, but you still get card versus cash transactions, sales by employee and graphs of sales within a chosen period of time. All reports are shown in a user-friendly interface. More complex reports are available if you upgrade the POS system to SumUp Point of Sale.

More and more small businesses benefit from affordable, cloud-based accounting software because it saves time. Xero’s features are hard to beat: inventory, payroll, workplace pensions, VAT computation, purchase orders, and so on.

Zettle integrates with Xero, QuickBooks and ANNA. SumUp does not sync with any accounting software, so you’re reliant on manually exporting sales to upload in your chosen accounting software.

A caveat to the Zettle-Xero integration: while the financial side syncs perfectly, the product levels do not. This means that if you sell an item with Zettle, the inventory in Xero will not be updated accordingly.

Neither SumUp nor Zettle has payroll functionality, but QuickBooks and Xero have payroll features through the Zettle integration.

SumUp can be used across Europe

Zettle can be used in the UK only. The company used to say they are working on making it possible for UK vendors to use it elsewhere in Europe, but no progress has been made on that claim for nearly a decade.

By default, SumUp does not work abroad either, but you can use it in countries covered by their operations in some circumstances. If you want to accept cards in Europe, just contact their customer support team with the dates you want to trade abroad.

Our verdict: close, but some things stand out

Both systems have attractive characteristics for budget-conscious entrepreneurs. The card readers are cheap, there are no fixed monthly costs, no minimum revenue requirements and the rates are competitive for small businesses. SumUp and Zettle are therefore both suitable for occasional and regular use alike.

That said, if you are just interested in accepting cards and have a fairly low sales volume, SumUp’s slightly lower transaction fee might save you a bit of money in the long run. For more integration options and the most advanced touchscreen terminal, it’s probably best to opt for Zettle.

“Commonalities and feature differences aside, I trust SumUp more as a long-term solution, as Zettle has lagged behind with new features since PayPal’s acquisition of the company. It’s a shame, because I like Zettle’s card terminals more.”

– Emily Sorensen, Senior Editor, MobileTransaction

For weekend payouts, a business account and the cheapest printed receipts, SumUp is the better choice. If remote and online payment options accessible from an app are important for your ability to sell in all situations, it is also hard to beat SumUp’s versatile payment options.
