SumUp Reviews in October 2026: User Ratings, Pros & Cons

I bought a sumup solo which worked successfully for the first few payments. Then it refused to accept the next four cards and locked. I have contacted customer services and received a message about how to return the machine for a refund. I wrote to have clarification on a few points and received a standard, thank you, we’ll look into this. Five days later, nothing. I eventually managed to extract a phone number from the online ‘help’ so that I could speak to a real person. A noisy party in ...

Sum up is perfect for our business as it's so easy to use

Sum up is perfect for our business as we normally trade from a field full of festival goers and most of them don't carry cash only card, it's so easy to use we have invested in more card readers so that all our staff can take payment not just us 2

Easy

Easy, reliable. Not overcharge. But need to work on customer service more. Didn't receive my bank card. Later called. They said it will be here shortly. Then after few weeks called again. Found card was lost somehow. So had to order again. They already despatched it. After a week or so still waiting. One my friend received bank card but not the machine. So he is still waiting for the machine.

Useless blocked card reader & terrible service.

Purchased a SumUp to take payments for our charity. Used a few times, but went to use it for a charity event in July of this year and the card reader was blocked but said on screen to contact customer support who would "send a brand new Solo". I contacted the customer support team who told me that, as the device was out of warranty, there was nothing they could do (despite the message on screen). I asked to speak to someone who could help (as the majority of responses from Support Agents ...

Worst possible PSP and you should decline their offerings due to bad software

Had a double booking during a taxi ride in Amsterdam. While the system stated „payment declined“, the payment went through and so I got charged double. Instead of realizing this error, support of SumUp declines dealing with it for already 4 months. As a result I REFUSE to use SumUp Terminals when offered by any kind of business. Get rid off your SumUp Terminals, as they might cause big time issues with AML (due to their bad software and processes!)! Funny enough SumUp denies this case ...

Worst company my account is been bloked…

Worst company my account is been bloked since 2 months phoned so many time same bs

Scam company!!

I am writing this review with absolute fury and frustration after my appalling experience with SumUp, a company that claims to provide payment solutions but in reality, operates like a scam. Let me start by sharing my ordeal with their refund process. SumUp reached out to me, requesting that I return their defective device for a refund. Foolishly, I believed them and followed their instructions, shipping the device back to them promptly. They assured me that I would receive my refund ...

Sum Up's lack of customer support.

I bought a Sum Up 3G+ card reader and receipt printer a year ago. Despite having the chip to allow it to access different internet providers it kept dropping its internet connection, sometimes at random but increasingly just as the payment went through. This meant the reader said payment successful at the moment of sale but then when I checked the payment records it reported them unsuccessful, obviously after the customer had left the shop. The card reader has also buzzed irritatingly from ...

Don't get sumup worst company they…

Don't get sumup worst company they delivered to wrong address and kept me waiting until they got the return to send out a new card reader been with them 4years no loyalty support lost week of no work Keep away from sumup terrible company

Not even managed to use it yet

Not even managed to use it yet. My account has been blocked for verification for 5 days already. Can’t even logon to use to chat to get help. Phoned customer service and all they did was say yes your account is being verified and yes we’ve received your id, you just have to wait. I totally get that things need to be checked but this is ridiculous Really not happy Gone to square and everything was sorted in a couple of hours.
