Editor's Take

Square offers POS and virtual terminal software and hardware for small businesses, restaurants, retailers, independent vendors and more. It offers a variety of handheld, countertop and mobile terminals with modern, streamlined designs that let your customers intuitively pay with credit and debit cards or cash.

You can set up operations using Square with only its free card reader plugged into your smartphone and the free Square POS app. This free solution is simple. You have to enter the price of every transaction, and there’s no way to connect it with inventory.

For more complex business needs, you can upgrade to a handheld device, which is best for restaurants, tablet or register. Square’s software offers a standard POS, plus restaurant and retail versions tailored to those industries.

POS Hardware

Square offers a wider variety of hardware for small to medium-sized businesses. You can use Square POS with everything from a free device connected to your smartphone to a robust in-store register.

SumUp’s countertop POS offers fewer hardware options than Square, but its stand-alone mobile devices may be more convenient than Square readers for businesses that travel a lot. Your vendors don’t have to connect to their smartphones. They connect to the internet and process transactions with stand-alone devices.


Software Features

SumUp offers a basic checkout experience, including a virtual card terminal and a simple item catalog. Square’s POS software offers a more robust point-of-sale experience, with software options tailored to restaurants or retail businesses.


Pricing

The Square contactless reader costs $49, compared with similar SumUp devices for $35, $49 or $99. But Square offers a free option that SumUp doesn’t; you can get a free magstripe reader to plug into your phone’s Lightning connector or headphone jack.

One-time pricing for Square countertop POS systems includes:

  • Square Stand (requires an iPad): $149
  • Square Terminal: $299
  • Square Register: $799

SumUp POS + Loyalty pricing starts at $0 per month, but you have to speak with a salesperson to get the cost of hardware and exact pricing for your business.


Transaction fees

Square charges a fee of 2.6% plus 10 cents per transaction for most transactions. If you have a Plus or Premium plan, the fee is 2.5% plus 10 cents or less. You can also accept buy-now, pay-later transactions with Afterpay for 6% plus 30 cents per transaction.

SumUp, in contrast, offers just one card-present rate of 2.75%. Manually keyed transactions run 3.25% plus 15 cents, and if you utilize the free invoicing features in the SumUp App you can send invoices for 2.90% plus 15 cents per transaction.

Bottom Line

Square and SumUp both offer simple solutions to help small business owners get up and running and process transactions quickly and easily. The services provide the hardware, software and merchant services needed to process your transactions online or in person; all you need to provide is a business bank account.

With its low-cost mobile offerings, SumUp may be best suited for solo business owners and micro businesses. If you’re a freelance service provider, an artist or crafter or a farm owner or baker selling goods at a market, SumUp’s card readers will be sufficient for your transactions.

If you run a more complex business, such as a restaurant or retail store, either SumUp or Square POS could meet your needs. Square offers more diverse hardware options and might be better able to grow to suit small and medium businesses.

However, with similar offerings from both Square and SumUp, the choice between the providers will likely come down to pricing that best aligns with your business.
