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

Helpfulness & understanding

The representative that dealt with my issue regarding my Sum-up card, not being able to carry out any transactions, spoke to me with care & consideration. She went above & beyond & was thorough went it also came to security questions before dealing with my card issue. Once the issue was dealt with, she kindly asked me if there was anything else that she could do to help, which I said no thank you, she then wished me a good day. Many thanks

Gross.

First off, card reader and SumUp account work fantasticly. Secondly, I've been trying to get a refund from them FOR TWO MONTHS! Somehow, two payments got taken out of my account for one card reader. Trying to get the one payment back has been excruciating. Here is a list of excuses I've heard: - "send us back the card reader we didn't send you." -" of course you can have a refund, it will take 3-4 weeks" refund never arrives" - and my personal favourite, that I heard today: "We already sent ...

Worst customer service I have ever experienced

I have been going back and forth for 6 months now trying to sort out an issue that happened because their form was confusing. All I wanted to do was change a name, and I was told I had to do one thing, then another instead, then another instead, before being told I had to do 5 very invasive things, all for them not to bother responding when I sent those. All the while they never responded unless I pushed them via email, and whenever I tried to make a complaint, they never put it in, or ...

Ignored when problem, then just terminated

Ok when it’s working, but the moment you have a problem they ignore emails, ignore the documents sent in, end chats and end calls and every person I spoke to wanted different documents, they ended up closing my account and stated they didn’t receive the documents I’d been sending in constantly. I’d assume if your not making the money they want they’ll terminate your connection.

Didn't understand what I was asking

Didn't understand what I was asking. I went onto chat twice and problem still occurs. Whenever I want to take a payment my Sumup Air automatically defaults to 20% VAT and I have to remember to change it to 0% VAT & Press Save. The next time it happens again it's on 20% VAT & have to repeat the same each time. It doesn't stay at 0% or even NO VAT when I press Save.

Customer Support is 0

Customer Support is 0. When your business needs to take money to survive but two weeks (and counting) later you still have not heard from them. Would you risk your business on them. It just isn't good enough. App ok but missing features. They have obviously not tried it in the real world. So it seems that if you want any support from SumUp you have to do it by leaving a bad review. Far quicker than waiting for support.

be careful with this company

be careful with this company. i ordered card machine and contacted them next day to cancel order they said they took my money and not able to refund even if i don't want card machine. so £180 is gone to this scammers. now i can imagine if i had the card machine from them probably wouldn't get paid aswel. good scum company

Great integrated solution

Great company. Had a super call with the sales agents and they patiently explained me their product suite. I'm getting their card reader and till solution, which integrates really well.

Horrible business account

These guys promise a lot but do nothing to help small business owners. For starters you can forget about next day settlement payments as they literally free style when and what time you should receive your money. It’s been 4 days and my card company have cleared 4 payments to my sum up business account which only I’ve received one payment only!! I’ve called sum up support team multiple times there’s no actual urgency to find out where the money is and how long it will take to receive my ...
