About - SumUp Payments, Ltd
Jan Deepen, Co-Founder
Fabiano Fialho Camperlingo, CEO
32-34 Great Marlborough Street | London, England, W1F 7JD I watched and waited for SumUp to hit the US for almost a year when it first started advertising its expansion to the US.
Checking the website frequently, emailing the staff with questions.So I was genuinely excited when the company officially opened for business in the US and I had a chance to test-drive and review the app and the hardware. Well over a year later, SumUp is still operating in the US, though in a quiet way. Maybe a bit quieter than Id hoped.
All the same, SumUp isnt just some new, untested provider angling to unseat Square or PayPal Here. The company is already well-established as a top option in Europe, which means it has experience with pay-as-you-go processing. Its also well-accustomed to dealing with EMV cards.
That should, in theory, translate to fewer growing pains and likely a bit more account stability than a brand-new hotshot processor.

Does not serve US or Canadian businesses. SumUp serves merchants in 31 countries on three continents. That’s pretty impressive, actually.
And it is possible to temporarily set up your account to process in one of these other countries, which is ideal for businesses that travel to trade shows and other events. Not only that, but SumUp is the fastest-growing private company in Europe according to Inc Magazine, adding 2,000 merchants and handling 100,000 transactions per day. I can’t tell you exactly how many merchants use SumUp, but I can guarantee it’s over 1 million, which is the number of merchants the company served after its merger with Payleven a couple of years ago.
So this is a big company — big enough that you don’t need to worry about it disappearing into the night. However, because SumUp is relatively new to the US market, there are unknowns.
Itll be hard to fully, effectively evaluate SumUp until we get an adequate number reports from American merchants. (If youre reading this, and youve used SumUp here in the States, please leave us your input!) It should also go without saying that the financial industry here is very, very different from European countries. That may translate into some different approaches to processing (such as a lack of manual entry).
However, we did look at reviews for the European countries where the company operates, because its a good way to establish a baseline for performance and quality of customer support. You can also find the first reports from merchants in the US trickling in. As we start to see more reports from American merchants, we will continue to update this review accordingly.
So, does SumUp live up to our expectations? Overall, yes. A few niggling details still need to be worked out, but overall, Im content with the feature set.
And it has all of the essentials you need for mobile processing, even if it doesn’t have a ton of bells and whistles. SumUp also supports omnichannel commerce so you can sell online and in person seamlessly. Finally, I like that the SumUp opted for phone support right out of the gate, which should lead to a better experience overall.
For all of these reasons, SumUp gets a 4-star rating out of 5 stars.If we saw some improved features, it might be able to climb the ranks a little, too, But until then, it’s holding steady with a general recommendation. Read on for a full breakdown of SumUps services and what we found relating to the companys customer service and reliability. Have experience with the company, especially in the US?
