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

Avoid this company at all costs.

Avoid this company at all costs. You may like the system when you start using it but will definitely end up with a blocked account and no access to your money. The security team will contact you asking ridiculous questions then give 2 choices of either keeping your money with them for 60 days or refund the money to the card holders directly (if you can contact them)

Amazing customer service

Amazing customer service. They help me a lot and really efficient.

Ander the assistant was very professional

Ander assisted me yesterday when I’ve had an enquiry about my SumUp account. He’s been ever so helpful, very professional, even empatic while explaining him that I am struggling with the new app layout. Thank you Ander ⭐️⭐️⭐️⭐️⭐️ Gabriela

Absolutely dreadful customer service

Absolutely dreadful customer service. Unfortunately, since I started with SumUp I feel the company has gone rapidly downhill. Transactions are slow, machines don’t work, transactions are declined and then take payment twice which is very embarrassing! Customer service is hard to get through to and they will not ‘own’ their mistakes. Think twice before you buy products from this company. I have moved to Dojo due the the poor customer service and connectivity!

I am very disappointed 😞😞😞

I am very disappointed over all off the management of the app. I was working with the app for one year and when I ask to change my personal bank details to a business account they closed permanently my account. I lost all my costumers details.

Shocking service, stole my money

Shocking service. This company closed my account without an explanation and are refusing to release my money. Small businesses should avoid at all costs. I passed a security check last week, nothing has changed since then so why am I being robbed!?! I can't seem to reply so I will edit my response. I am annoyed you closed my account, but it happens, that's fine. I'm angry you are keeping my money for an undisclosed amount of time. Money I need to run my business and feed my kids. And you ...

Good service very helpful

Good service

SUMUP, anyone, please help?

Hey SumUp, I was wondering if you could help because I really want this to work out but for some reason I am not getting anything from your support crew. It is Day 4 from signing up and unfortunately on Day 1 I did two Payment Links that didn’t work (one I tried twice and the other 3 times). I have been trying to apologise on your behalf to my customers but it feels like I am the one who is looking stupid. Anyway I have chatted to Sam the chat bot who I feel I have bonded with but ...
