SumUp Solo with Printer VS Zettle Terminal with Printer

This solution can stand alone. It is ideal if you do not require all the advanced features of the mobile POS app. Moreover, the charging dock can have a receipt printer if needed. You can then print your customers’ card tickets.

The Zettle Terminal is Zettle’s latest model. It operates with a SIM card for on-the-go use like the Solo. Similarly, its charging dock can also print customer card tickets if needed.

-> Verdict: SumUp Solo wins for value for money


Which POS App is the Best?

If you do not have the Solo reader, you use the mobile app to process payments.

SumUp’s POS (cash register software) app works well. The bluetooth connection of the SumUp Air is particularly fast and reliable.

You can do simple things like create a product library with images, set prices, and organize categories.

The cash register software offers advanced features such as creating gift cards, QR codes, and payment links. It also allows offering tips and managing invoices. Plus, it offers the possibility to open an online store to sell your items.

With Zettle, you can do a lot of things, but not create an online store or manage invoices.

If you are a small business and need something simple, the SumUp and Zettle apps are perfect for you. Otherwise, we recommend SumUp, which is better if you plan to use more features.

-> Verdict: SumUp wins


Which is more cost-effective?

Neither SumUp nor Zettle charge monthly fees or require you to sign a contract with them. No hidden monthly fees such as rental fees, for example. You just need to buy your card reader and pay your transaction fees, that’s it.

You will have no security concerns with SumUp or Zettle.

-> Verdict: Tie


Who Offers the Best Customer Support?

SumUp has improved its online customer service with guides to solve problems you might encounter.

If you can’t find the answer, contact them by email, but it can be slow because of their ticket system. For quick contact, they offer telephone support from Monday to Saturday from 9 am to 8 pm.

Zettle also has a wide selection of written resources as well as an email messaging system working with tickets. Their telephone lines are accessible between 9 am and 5 pm on weekdays.

Our Conclusion: Who Tops the List?

Zettle and SumUp have excellent customer reviews and are serious companies.

Zettle offers simple products for small businesses. SumUp is ideal for merchants with bigger needs or seeking a full professional POS solution.

SumUp’s advantage lies in the fact that they offer robust and inexpensive readers. If you find their Solo reader appealing, which does not need a mobile phone, it is an excellent choice. Both POS apps offer good features, but again, it’s SumUp that stands out. With its additional billing features and online store creation, it is the best option for a growing business.

The winner is therefore SumUp.
