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

Do not use SumUp. They are scammer.

I was working on my website that’s why I toke 2 payment from customer by sumup link. And next day they freeze my payout instead of giving me my money. After that they asked for some documents, I provide them all documents. After 2 week they close my Sumup profile for no reason. And they said I’ll receive my payout after 2 month which is 17th of May. And today is 25th May still I haven’t received my money. I contact with customer service they said someone will contact with me on Monday but ...

I am a Sum up customer for 5 years or more . But recently I have contacted customer service and technical support team for various issues related with my invoicing . I never seen a bunch clueless people before . Always say email them after once you finish call , someone will contact.Unfortunately no one will contact you . Just waste of time , I had enough updated: Still email conversation going on ,so far can't even sort out a single issue which I have raised. Still asking screen shot ...

A nightmare to deal with

Worse customer service and tech depart.No one knows what to do , allways say screen shot or email after the calls , so they can runaway . Waste of your time and ruin your business.I been using them few years as a back up , sadly it's time to leave .Something went wrong with this company. It’s like a sinking ship now.

Slow and inefficient service. Unwanted marketing.

Well. this hasn't been a good start. I purchased a sumup card reader in december as a back up to my current card reader supplier (zettle). Finally got around to setting my account up after a winter break from the craft fair season, and am already considering giving up on sumup and getting rid of the card reader. Firstly, the bank details were incorrect. I tried to change them and was unable to do so via the website, so I contacted suppor via chat. The website was not working to do this, ...

Been with sum up a while however they will not allow refunds to customers once you’ve been paid out ( even though I’d withheld sufficient funds within the account balance) Said I need to refund customer bank transfer. Makes you look totally unprofessional as a retailer , Iv been trading over 14 years and won’t continue to use a provider who can’t offer a simple card transaction reversal.

AVOID

We opened a business account after wanting to get a SumUp POS system for our new business, and thought having everything linked up would make sense. How wrong we were. We had confirmation that the account was open and was usable straight away and that a card had been sent out, which was great(we thought). We deposited our first payment, which was going to purchase the POS system. We waited for this money to clear, and the next day received an email saying the payment was being held until we ...

Device is blocked, buy a new one...

Device is blocked. Answer from Sumup supporet (his name is often Sam) : "Unfortunately, once we see that message means that the card reader is no longer able to be used. So I would advise ordering a new one from the website or go to a near store a buy a new one" Great support. Unbelivable that they are still in business.
