Square vs SumUp

What are Square and SumUp?

Before comparing these two giants, let’s first understand what each of them offers.

Square

Founded by Twitter co-founder Jack Dorsey in 2009, Square is an American financial services and mobile payment company that aims to simplify payment processing for businesses. Its point-of-sale (POS) system includes hardware and software products to help businesses of all sizes accept payments both in-store and online.

SumUp

SumUp, on the other hand, is a UK-based mobile point-of-sale company founded in 2011. Similar to Square, SumUp provides small and medium-sized businesses with the ability to process card payments in a simple, secure, and cost-effective way. Their primary offering is a card reader, which pairs with a mobile app to facilitate card payments.

Pricing – a key consideration

One of the most critical aspects when choosing a payment solution is pricing.

Square’s pricing structure

Square provides a fee structure that is easy to understand. There’s no set-up or monthly fee; instead, it charges a flat rate for each transaction. For card-present transactions using the Square reader, the charge is 1.75% of the transaction value. For online or keyed-in transactions, the rate is 2.5%.

SumUp’s pricing structure

Similarly, SumUp also operates on a no monthly fee, pay-per-use basis. However, SumUp charges a lower flat rate of 1.69% for all types of transactions, giving it a slight edge over Square in this category.

Hardware and software – which provides better options?

The type and quality of hardware and software offered by a payment solutions provider can significantly impact the ease and efficiency of processing payments.

Square’s offerings

Square’s product range includes the Square Stand, Square Register, and Square Terminal, among others. These are robust and stylish hardware options that can process contactless, chip and PIN, and mobile wallet payments. They also provide software for inventory management, customer data tracking, invoicing, and more.

SumUp’s offerings

SumUp, on the other hand, is more focused and minimalistic in its offerings. The SumUp Air Card Reader is their primary product. It’s a compact, portable device that allows businesses to accept credit, debit, and contactless payments. They also provide a mobile app for inventory management and sales tracking.

While SumUp’s offerings are straightforward and easy to use, Square provides a broader range of options that can cater to more extensive or complex business operations.

Integrations – expanding your business capabilities

Both Square and SumUp provide integrations with various platforms and software to enhance your business operations.

Square integrations

Square offers an impressive array of integrations. It links up with e-commerce platforms such as WooCommerce and BigCommerce, and also integrates with a range of accounting, inventory, and customer relationship management software.

SumUp integrations

SumUp provides fewer integrations but covers key areas. It works with popular e-commerce platforms like Wix and Shopify. There are also integrations for accounting software, but the options are fewer than Square’s.

Overall, Square has an edge in this category due to its wider array of integrations.

Customer support – ensuring you’re never left in the lurch

Customer support is crucial, as timely help can save businesses from potential losses during technical difficulties.

Square’s customer support

Square provides a comprehensive support centre with articles and guides. It also offers live chat, phone support, and a community forum where users can help each other.

SumUp’s customer support

SumUp also provides a support centre with various resources. However, SumUp’s live support (phone and email) is available only during specific hours, and they don’t offer live chat support.

Given the broader support options, Square takes the lead in this aspect.

Conclusion – Square vs SumUp

Choosing between Square vs SumUp depends largely on your business’s specific needs.

If you’re a small business owner looking for a straightforward, cost-effective solution, SumUp’s lower transaction fees and simple setup could be appealing.

However, if you’re running a larger business or require more sophisticated features and integrations, Square’s comprehensive offerings may be worth the slightly higher transaction fees.

Remember, it’s crucial to consider your business’s specific requirements, your budget, and the scale of your operations before making your choice.
