What Is SumUp?

SumUp is a payment service provider that offers in-person payment processing through its SumUp app and mobile SumUp card reader. The SumUp app is similar to its closest competitors, Square and PayPal Zettle, making SumUp a good option for low-volume and mobile sales.

Besides SumUp’s fees being lower than Square’s for small tickets, SumUp’s pocket-sized credit card reader has features the Square mobile reader doesn’t have, giving SumUp a slight leg up on its competition. SumUp’s quality as a mobile processing solution is reflected in the many positive SumUp reviews, at least from international merchants.

At the moment, SumUp offers more payment processing features and merchant services in the UK and Europe than it does in the United States. US merchants don’t yet have access to eCommerce payment processing and can only process a card-not-present transaction by keying it into SumUp’s optional virtual terminal. Nonetheless, it’s still great (and a viable alternative to Square) for mobile and retail-only merchants due to its affordable processing equipment and competitive processing rates.

How does SumUp work?

SumUp lets businesses accept card payments in person, through an online invoice, with payment links or over the phone.

  1. The company’s two all-white readers with black-and-white displays are among the cheapest ways to start accepting in-person payments. Using SumUp doesn’t require a long-term contract, and there’s no monthly fee to use it. One of the readers is a standalone device; to use it, you don’t need to be tethered to a phone or register. This flexibility can be a plus, especially if you move locations frequently and don’t want to buy multiple tablets or phones.

  2. The flipside of SumUp’s minimalist approach is that it has a limited feature set relative to other companies, especially those that offer complete point-of-sale, or POS, systems. SumUp says it has a POS system coming soon, but until then users must rely on an app that has some components POS systems have, like the option to build an item catalog, but that lacks more complex features, like the ability to build a floor plan of a restaurant or quickly incorporate a customer loyalty program. Although other companies offer dozens of reports, you’ll have access to only a few reports with SumUp, like transaction and revenue summaries.

  3. In addition to in-person payments, you can use SumUp to send online invoices to customers. You’ll also have access to payment links and a virtual terminal that lets you accept over-the-phone ("manually keyed") payments.
