| SumUp Review | Square Review |
Comparing Square vs SumUp fees, both provide competitive flat-rate pricing structures for their payment processing solutions. Their processing fees do not significantly differ, except for invoicing, where SumUp offers a lower transaction fee.
Both payment service providers have zero monthly fees if you only need the basic payment processing features. However, if your business needs a full POS system, Square beats SumUp because of SumUp’s $199 monthly fee and one-time initial $400 set-up fee for its POS, which can be hefty for new small businesses.
When it comes to hardware, a Square plan comes with a free magstripe reader and has the Tap to Pay on iPhone and Android features, which let you use compatible mobile phones as contactless card readers. This means new merchants can sign up for Square and start accepting in-person card payments with absolutely zero initial costs if they have a compatible mobile device. If you prefer to have a dedicated card reader that can take EMV and NFC payments, SumUp’s cheapest device is more affordable than Square’s.

| SumUp Review | Square Review |
When it comes to payment types supported, both Square and SumUp earned high scores in our evaluation. Square still offers a more complete solution, as SumUp does not offer recurring billing.
If you would like to receive payments via your website or online store, SumUp offers limited integrations. It only lists WooCommerce, Wix, and PrestaShop as its ecommerce partner solutions on its website. If your website or online store does not use any of these three platforms, you will need to rely on higher-level developer skills to use SumUp’s APIs (application programming interfaces) and SDKs (software development kits).
Square, on the other hand, lets you build your own ecommerce website through its free Square Online platform. If you prefer to use a different ecommerce platform, Square can be easily integrated with some of the most popular ecommerce platforms such as WooCommerce, Wix, Magento, BigCommerce, WordPress, and Drupal Commerce. It also has developer APIs for integrating Square into custom-built websites.

| SumUp Review | Square Review |
Square and SumUp have clearer differences when it comes to features, and Square has a significant lead over SumUp in this category. The only edge SumUp has over Square is its cross-border support. Although Square is available in eight countries, merchants cannot receive payments while in another country. Accepting international payments while in the home country where the Square account was opened is not a problem, but if you travel and need to accept payments while traveling, you cannot do it through Square. SumUp, on the other hand, is available in 31 countries and offers cross-border support within Europe.
SumUp vs Square Expert Score
Square is always a top provider in many of our guides, and it holds up its solid reputation in our Square vs SumUp comparison. It allows small businesses to start accepting payments without any fixed monthly costs, while providing cost-effective solutions for scaling up their operations.
SumUp still earned good scores, but didn’t quite hit the mark when it comes to easy and affordable business scalability and integrations. For an all-in-one payment solution, Square still gets our vote.
SumUp
4.06 / 5
SumUp offers a free plan that lets merchants accept payments through its mobile payment app. Its basic mobile card reader is one of the cheapest out there, allowing businesses to take card payments with very little initial costs.
However, growing businesses that require a full POS solution will need to shell out $199 every month, aside from the initial $400 POS set-up fee. A new small business or startup might find the initial costs of SumUp’s POS solution hefty.
Although these SumUp fees make it more expensive, it is still a good option for small businesses that require low-volume payment processing, such as freelancers, professionals, periodic farmers market sellers, service providers, and other solopreneurs.
Square
4.69 / 5
Square has consistently performed strongly in our assessments because of its small business-friendly pricing and features. Merchants that start with Square can feel confident that they can start with low-cost basic payment processing and have the support to scale up their business when needed.
It provides flexible POS software, a wide range of business management tools, cost-effective yet high-quality hardware, and versatile payment processing capabilities. No matter how your small business prefers to accept payments, Square offers a reliable all-in-one payment solution.
