SumUp Reviews in July 2025: User Ratings, Pros & Cons

Unethical merchant using Sumup.

I contacted Sumup support by email over a week ago but as yet have had no reply. The issue is that a merchant in Spain is using the sumup platform to take security deposits from tourists and never returns the money. I have sent the details. Sumup should take some action to stop this scam on its platform.

Chat service is a waste of time

Chat service is a waste of time. Long queue to be allowed to pose question (times out in 7 mins if you don't spot you have reached the top) then no acknowledgment that they have read your question. I checked - they had seen it: sorry for delay. Then booted out of chat (without having received an answer) because it had taken too long. Absolute Rubbish. Avoid if you can (but are competitors any better?)

Do yourself a favour and don't loose…

Dire customer service

I was kept on the phone being told you call will be answered in approx 5 mins. 35 minutes later being told they were too busy to answer my call and was cut off. ...

I am a consumer

I am a consumer. My merchant is based in France and uses SumUp to process his invoices. I am based in the UK. I downloaded the consumer app on the invoice.

I tried to withdraw my money back to my bank account. It keeps giving me an error message "Oops, there was an issue. An error occurred on our ...
