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

Sumup payments are regularly delayed…

Sumup payments are regularly delayed for some time. My payments are set to 'every day' and I am getting payments once or twice a week. It is Monday and no money transfer whatsoever. And it is getting worse and worse. And no response from Sumup helpdesk at all. Something is not okey with This company.

Not able to get a response to my issue

I want to change my account name and bank details but not getting any response. I’ve asked them to let me know that if it’s not possible that I want to then close my account and stop getting people to pay me via Sumup!! I’ve money sitting there but I can’t access it. Also I called their customer service who told me the reader was purchased last year which is ridiculous because I bought it a week ago. Are they selling refurbished readers?? I’m feeling uneasy with Sumup and stuck because I ...

It’s very easy to use and fast payment…

It’s very easy to use and fast payment and reasonable fees thanks.

Zero customer service

Try to order a new card for over 6 months. Not helpful at all.Call center people have no clue how to deal with customer complaints. When I asked to speak with manager being told they are sitting abroad can’t transfer call to anyone.

Absolutely jokers clowns

Absolutely jokers clowns. Time wasters. I should have just stuck to square it’s been 2 weeks I’ve emailed several times now to change my bank details and they are not interested. Stay clear from these wa****s

Terrible support and customer service

Everything is great until there is a problem with a payment device (which happens regularly) and then the support is appalling. Agents who don’t understand and read from scripts, bureaucratic processes, refusals to send replacement devices even if you offer to pay for them and agents who hang up when it gets difficult for them. The overriding attitude from their customer service is “we don’t care”. The customer care is just non-existent and very happy to leave us stranded with a ...

GET OUT while you can

GET OUT while you can! My mailbox has been hacked and SUMUP won't help! FLEE FLEE FLEE I gave them copies of my invoices and ID card. Nothing to do, they reply with a standard e-mail. As long as everything's okay, it's all good. But as soon as there's a problem, that's it, the company is based in IRELAND. So there's nothing you can do about it.

Disgusting customer service

Merchant number MNFMQSNZ I ordered the wrong thing on sum up and for a week now I've tried to return it but I keep getting passed around and no one is taking responsibility, twice its been escalated and now I'm told I will get a manager to call me I've had it a week now and for a week I've tried to return it, absolutely shocking customer service, I wish you could get lower than a 1 as that's what I would have scored them they are less than useless

i bought one of their sumup air devices…

i bought one of their sumup air devices and it worked fine at first until i logged in to my account on browser not the mobile app to see when my payouts are going, just to find out that they declined my Uk based bank account and say that it is wrong and wont even accept changing it or re entering it again. none of this was even showing in the mobile app till now. i sent an email to support and they dont even answer me back really bad experince

How an offer make you lose clients

Finally Sarah from their UK support team could help me explaining that Local cards is not that they are issued in the same country that you accept the payment in, but apparently VISA/Mastercard is always local cards. In their text on the site they show: *La comisión por transacción del 0,75 % se aplica a todas las tarjetas de consumidores emitidas en el EEE. Para tarjetas internacionales y comerciales (incluida American Express), se aplica un sobrecargo adicional del 1 % Or on the English ...
