Integrations and Payment Options

Both SumUp and Square excel in providing versatile payment solutions, but their approach to integrations and payment options sets them apart in significant ways.


SumUp’s focus on simplicity is evident in its straightforward payment options. While the platform can handle online and remote payments, it may be considered more basic compared to Square. Notably, SumUp doesn’t offer online store functionality yet, but this streamlined approach allows SumUp to work effortlessly out of the box.

A standout feature of SumUp’s card readers is their ability to connect directly to your cell network, even without Wi-Fi. This convenience makes it ideal for on-the-go businesses like bazaars or trade shows, as you don’t need to invest in multiple phones or tablets.

In addition to in-person payments, SumUp allows businesses to send online invoices to customers, providing added convenience and flexibility. Remote payment options like payment links and a virtual terminal also enable you to accept over-the-phone (“manually keyed”) payments. Lastly, SumUp supports major credit cards and popular mobile wallets, ensuring a seamless payment experience for customers.


Square’s comprehensive approach to integrations and payment options is a significant strength. With support for major credit card networks, mobile wallets, and NFC service providers, Square caters to both online and in-person transactions with ease.

While Square does offer several add-on business tools that come with a monthly cost, these tools provide essential features that can propel your business to the next level, making Square an excellent choice for those looking to scale and grow their ventures.


Understanding the pricing and transaction fees associated with payment processing platforms is essential for businesses seeking cost-effective solutions. Let’s dive into the pricing models of SumUp and Square to help you make an informed decision.


SumUp adopts a straightforward pay-as-you-go pricing model, ensuring transparency and ease of use for merchants. For in-person transactions, SumUp charges a flat fee of 2.75%.

Additionally, SumUp provides hardware for which you’ll need to make an initial investment.

One of the significant advantages of using SumUp is the absence of monthly contracts, minimums, or obligations. This flexibility allows businesses to tailor their payment processing to their specific needs without being tied down by long-term commitments.


Square offers businesses a range of pricing plans to suit their individual requirements. The entry-level plan adopts a pay-as-you-go approach, ensuring there are no setup fees or monthly charges—businesses only pay when they process a payment.

For standard transactions, Square charges a processing fee of 2.6% plus $0.10 for contactless payments, swiped or inserted chip cards, and swiped magstripe cards. Payments that are manually keyed-in, processed using Card on File, or manually entered using Virtual Terminal incur a fee of 3.5% plus $0.15.
