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

I sent my first payment across 6 days…

I sent my first payment across 6 days ago and they wouldn’t payout the funds to my nominated bank account because of verification problems I’d sent passport/driving licence/bank statements/verified my email address and phone/ sent a invoice matching the amount and after two days they emailed asking buisness cards or a Facebook profile before they could release the money, so I had to set up a Facebook page as not done as a new company I had to speak to someone and beg on the phone and say ...

Up until now I have been very happy…

Up until now I have been very happy with SumUp as a general all round platform. Been a customer for just under 5 years woth no real issues. If the staff were as reliable and efficient as the platform is, it would be a superb company, alas, this has not been the case since 0803 hrs last Friday. I used the BACS facility to pay a sub-contractor / good friend who I work with regularly, guess what, yes, the payment was held for verification. Having made numerous phone calls, sent emails and ...

Poor customer service & experience

I used SumUp for an event my company did last week in Copenhagen. The customer service was incredibly poor in terms of getting in contact with them. We transacted in the five digits of revenue in two days, however I would receive emails from SumUp stating that they were only paying out 65Kr. I contacted them about this and they adjusted the payout to 1 out of 2 days amounts of the total transactions (30%). They continued to lack the transactions for paying out the 1st day which was far ...

App Refund Process is Broken

Thanks for prompt response after posting this one star review. Some may find following info useful. Objective: To get a customer a part refund (say return of a holiday let damage deposit). Problem. The refund screen sequences that is defined in the Android App and my PC web portal DOES NOT WORK even when there are ample funds in my SumUp business account. The point here is that there is the functionality to give the user a direct refund capability but it is broken or has been disabled ...

Been gaslighted by SumUp

I recently had 2 transactions later fail that were originally approved. I was told by their customer services that I wasn’t the only one that this had happened to on Saturday 27th August but they’ve refused to honour these transactions instead they’ve sent me a dummies guide in how to take money . I’ve only been in the retail business for 33 years and using this type of machine for as long as they’ve been out.

Sumup SOLO Don't Buy!!!!!

Sumup merchant ref. MDMHCQDF I have had the WORST experience of my life in trying to get a refund from sumup. I bought their Solo card reader. It DOESN'T do what it PROMISES to do. It REFUSES to send text receipts to my mobile or in fact ANY mobile phone. I have had a replacement unit sent out to me but THIS ALSO won't send a text receipt. The Solo card readers software is FAULTED and sumup will NOT address this FACT. I have contacted them NUMEROUS times asking for a refund and they ...

APPALLING!!!

APPALLING! Where to start? My original SumUp Air has always been fine and does what it says however I recently decided to upgrade to the larger POS system. I thought this would be a seamless link to my existing account. They were quick to sell me the product and send it out(which to make another point was not what is pictured on all of their marketing material, a part of my decision to upgrade in the first place) beyond that the ‘customer service’ has been APPALLING!!! With different ...

Transformed my business

A friend recommended Sum up for contactless payments. I ordered online. It arrived in 2 days. It was inexpensive and it took me 15 minutes ot set it all up. I was able to take contactless payments right away. I was so impressed.
