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

Unreliable and unprofessional, account disabled without warning

Setup my account and had to provide them with personal details in order to verify and activate my account. So far so good and my account worked for a few weeks. Went to try a card payment about two weeks ago and all forms were declined and I had no idea why. I even logged out but when I tried logging in it complained my username or password was wrong every time. I could reset it but same error every time. Sent an email to support and it took two weeks to even respond! And the reason is my ...

Account closed without reason or…

Account closed without reason or notice. I run an FCA authorised mortgage broker Ltd company and so the risk etc is effectively nil given the regulation and insurance in this field however Sun up just emailed and closed the account without warning or notice the same day as I’ve told a client they can pay by card for their broker fee. Disgusting service, will not use or recommend in the future

Horrendous company

Horrendous company. Perhaps the product works OK, but I never got that far. The customer service line is so utterly useless that I am going to re-advertise the product I purchased on ebay and buy another companies product. Sumup FORCE people to use their Business Account - FORCE THEM - then say the person can opt out and change it to their own personal account afterwards. After many emails and telephone calls I can tell you that you can't, no matter what the person says on the 'help' desk, ...

I have been a customer for over 6 years…

I have been a customer for over 6 years and use my machine every day 6 days a week. I nab had cash advance to help my business 3 times so far and every time I’ve paid early and repaid more than 3 months early. I’ve asked for another advance numerous times and saying I’m not eligible I don’t understand when I’ve never missed a payment. This is really bad service and I’m looking as moving to another card machine

If I could put 0 stars I would

If I could put 0 stars I would. Had nothing but hassle with these the first payment I took on my card reader they locked until I sent evidence of business with invoice and was told after this would never happen again took 2 more payments and they terminated the account with no way of me getting my funds out of the account. Now got to go back to the customers after they get a refund to try get payment another way sumup are useless avoid at all costs

Useless customer service

The service itself regarding payments is not bad, however customer service agents are completely useless. They have no clue on what to do. I chatted with an agent, then called because I couldn't find the way to charge VAT correctly on the app. Nobody was able to give me proper instructions on how to do so. The only thing they're good at is telling you to send an email. I had to review the entire app on my own to finally find the solution. Same happened regarding updating business ...

Terrible service, you just get ignored. Rude.

I became a customer and got the card reader machine. I then made an application for a better percentage fee rate because our card receipts are high value and volume and understood that better rates may apply. After ten days I heard nothing other than a computer acknowledgement of the request. I went on to a chat to find out what had happened, to be told that the case had been closed. Nobody contacted me about it AT ALL, they just simply ignored me. TERRIBLE SERVICE Following reply from ...

I've used multiple different card reader providers and SumUp is by far the worst

I've complained previously about SumUp for multiple reasons - they saw my complaint on here and have done nothing since. I've complained to the financial ombudsman because my complaint has been ignored They've been charging me the wrong rate % and when I pulled them up on it (back in OCT!) they have dragged their heels and confirmed they owe me a refund and still have not refunded me to this day. That is just the cherry on the cake with their customer service and their product. I've used ...

Fraudulent company !!!!

Fraudulent company !!!! Set our account up, passed all our company and identification checks and then allowed a test transaction to go through gaining our trust then 3 weeks later when we actually started using the system the opened a review on our account after 2 transactions totalling a few hundred, they requested invoices from me and then told me the invoice where made through sum up so cant be used in a review, however we use another company for our invoices and have evidenced this to ...
