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

Sumup resolved my problem by making personal contact

Sumup resolved my problem by making person to person phone contact and working through the issue until the problem was identified and resolved. I believe the person to person contact reduces stress against other methods and helps the customer relax more knowing some one at the company has made contact.

The technician was incredibly helpful and most patient as she talked me through various processes to try and rectify the problem I had with my reader. I couldn't rate the service highly enough.

EXCELLENT SERVICE FROM SUMUP.

EXCELLENT SERVICE FROM SUMUP. We reached our credit limit on Sumup, which resulted in the machine being turned off. One 'phonecall followed up by an e-mail led to it's immediate reinstatement. Well done to all at Sumup!

Problem with connectivity.

Used to be fine, now only connects via 3G for approx 1 in 10 attempted transactions. Resulting in loss of business. 5 weeks and 5 plus attempts to speak with someone in customer services has resulted in no callback/support as promised on online 'chat' on 2 occasions.
