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

If I could rate as zero I would...

If I could rate as zero I would... Sumup closed my profile without explanation or warning. There's no way to call them and despite many emails and using their online"support" I still have no information on why the profile was closed. I can't access money in the account and I can't use the device for sales. There's no respect for customers and I would advise any one thinking about using Sumup to look elsewhere. They have caused me huge stress and wasted a lot of my time. Looking at other ...

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 ...

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, ...

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 ...

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.

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.
