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

Simply brilliant

Brilliant! I was worried about a potential scam and used the chat bot who connected me to a human and my querie was solved in seconds. Fast, clear, simple, I got the help I needed very easily. And prior to that, I had been sent spontaneously a newer version of my reader as I was using the previous hardware. SumUp has been nothing but efficient in the 18 months I have been using it.

Fantastic! It was quick and easy

Absolutely awful customer service

I am still waiting for my sum=up machine after 12 months after paying in advance. It seems impossible to speak to a human being. I would like a credit or my start up bundle to be delivered

My card reader has stopped working

My card reader has stopped working. All I got was that this sometimes happens and I have to buy a new one. My comment that I thought good customer service would be sending me another was not even answered. I have been a customer for several years. Very poor Get rid of bots. Every day use is great I have been offered a discount on a new card reader. Unfortunately I have already bought one as I needed one straightaway.

Sumup accepts payment for illegal drugs

My son has been able to purchase illegal bodybuilding drugs from the website uksarms.co.uk using Sumup to accept card payments and has suffered severe health issues! This includes SARMs and prescription medication such as Enclomiphene under the guise of "research use" This is in clear violation of Sumup's own Restricted Business terms, and I reported this to several email addresses with full evidence including investigations@, info@, sales@ and support@ I initially got a response from ...

Customer service non existant

Tried to use sum up machine on NYE for important busy sales night, machine wouldn't work- tried to log in online, got a prompt saying "Our team is verifying your account and will contact you" despite emailing, its been 10 days now with no response

Customer support is an oxymoron

Total failure of customer support in dealing with non-functioning devices; prolonged exchange of e-mails failed to resolve. Refusal to replace devices without charge; inadequate response to complaint so waiting for a further response to complaint about the complaint. No mechanism to have constructive person to person dialogue instead constantly sending e-mails to generic address with replies from different people each time - no continuity - dogmatic adhesion to algorithms and apparent ...

Customer service poor

Tried to amend my business name to reflect my business and this is becoming a farce. Still waiting for someone to deal with it.
