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

It's OK but I think other companies would offer better

I've been using Sumup for over two years for my business. The invoicing system is good and the card reader is fine (but not perfect), and their support is not great. In our first week of business our card reader started to decline payments as we'd apparently reached our sales limit of £5k? They cleared the limit eventually, but obvs it was embarrassing for the customers. We have a big card reader that prints off receipts, but when I've asked in the past how I take a card payment over the ...

Just buy another ! Stock reply from Sumup

Device was stored in its box for 8 months, in a nice warm and safe environment when we turned it on it comes up saying Blocked contact Sumup who will send us a brand new Solo. Thinking thats not bad, then we find out that is blatantly not true, they will only replace if its under warranty, they refuse to fix it, and are unhelpful as they won't even take a complaint, you have to email in. So I did some research and low and behold I'm not the first and it seems many reasons can cause this ...

We are a charitable organisation that uses our SumUp machine to raise valuable funds. Our machine has not been used very often and now that it is out of warranty there is an error code saying that we can no longer use it, but that SumUp would replace. When I messaged SumUp they said they would not replace and have not replied to my further email. Funny how this happens just as the machine is out of warranty, very disappointing. We can not afford to replace this machine, looking at the ...

One of the worst customer experiences i've ever had. Refused to let me cancel an order at the point of sale. Spent most of a Sunday on a virtual chat with a customer support agent who did their best to make things difficult, obfuscate and not help. Then switched on to the phone to another agent who did the same thing. Was repeatedly told they do not have the "authorization" to cancel the order and that another team does. Was then told I could not be connected to that other team because ...

My device was blocked MSN/105019363540/ AIR1E305

My device was blocked, and I try to contact the customer service to unblock it The services I received was so bad that I could not believe this is going on in UK. I was told my device was blocked for security reason after going through the security reason with me I expect my device to be unblock instead of that I was asked to buy a new card reader even if the one I have is still walking but all what they are trying is just a market a new product to me I tried to talk to his supervisor ...

Over complicated system for verification

Advised them that the card reader was not charging. Machine a month old and was advised a replacement would be sent. It arrived within 48hrs but was the wrong machine. Tried to advise them of the mistake, three phone calls made and on the last call I was constantly asked for the serial number of the replacement machine but was constantly told it was an incorrect number. They insisted the number was on the machine, it was not, it was on the box it came in. The line then broke up and I could ...

Sum up was fine until it updated the…

Sum up was fine until it updated the card machine and added VAT. Caused numerous problems and I had to give customers cash back! Card machine frequently declines cards and stops working, then updates when we are extremely busy! Now cannot log into my own account to access contact from SumUp as one card machine keeps declining cards including my own as a test! Not a happy customer!

Do not use SumUp Pay

Do not use SumUp and specifically Do NOT use “SumUp Pay”. Claims everywhere you can withdraw at any time but that’s a lie! Not even an option and now many is held against my wishes with no choice but to spend it before my account can be closed. Terrible follow up service waiting days for a reply. My bank also treated it as a cash transaction so charged me up front and interest! No offer of help at all.
