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

Unstable machines & poor support

I've owned four of these now - this is the last time, when this breaks - I will try another company. Never SumUp again. The devices lock you out if they get too cold, someone puts the card in correctly, or it gets knocked. Then - if you are out of their warranty - they will not help - instead - they tell you to go buy a new one, and you are left with a useless block of plastic you paid £100 for. Way too sensitive if you're out in the real world, what a wasteful and greedy ...

Customer service is dreadful

Customer service is dreadful. I have a promo code to use. Added it to my account and it's not showing and won't let me add again. No help from emails to Customer Service. Keep asking me to send the same information over and over. Starting to think this is a complete con. Amazingly they have now sent marketing emails to the email address they keep insisting is not on my account!! Your response on the 13th of February has answered nothing at all. I have sent a response to your reply.

Great addition for getting paid

Great wee addition to my working day. it allows me to get paid as I work, regular payments then into my bank. great way to do business. More so these as less people use or carry cash. Works great along with my mobile phone.

Appalling customer service - avoid

I wish I'd read the reviews about Sumup before I purchased a card reader. Fortunately I can take it back for a refund. Be warned that their customer service is appalling. As someone who engages customer service departments a reasonable amount in my professional life as a handyman, I can't remember a time when I came across a company with such dreadful after sales care. I have tried twice to speak to someone on the phone. When I eventually got through, the quality of the line itself was ...

Very BAD company

Very BAD company. This company is holding our money and there is no dispute from any customer. They closed the account without any notice and we have no access to our hard earned money. I real wish we had never open account with them. We certain will never used them again. SumUp, Close your useless account and release my money ASAP

Shocking service

Shocking service, they closed my account down after 4 days notice. They still hold the balance of my account of which I’ve been trying to get for over 4 weeks now. Getting past from pillar to post. Very very frustrating. Stay well clear Thank you for your reply, I have no idea why you only gave me 4 days to respond before you closed my account down, I was away on holiday at the time. Plus why haven’t you send me my remaining balance that you still hold??? I’ve sent all the relevant proof ...

Avoid at all costs

Avoid at all costs, supports fraudulent activities! They will now try and get my review taken down, then they will leave a comment and say they will be in touch…. They won’t. Avoid the headaches and look elsewhere! Ref 26392421 * The company you support is fraudulent, many customers have been affected, the ethics of your company you should ban this trader. Even the small claims agreed. Shocking service. TO EVERYONE ELSE please read this as a warning and avoid at all costs!!! *Sumup ...

Absolute Scam

Absolute Scam, our account was hacked within minutes of setting up with our account details changed despite it being set up through our bank Starling it was changed to a HSBC account the other side of the UK. Payments were never recieved and despite us picking up on the account details being changed we received no help from SumUp. DO NOT USE! Their call centers are abroad and useless and after over a month we have still not recieved their complaints procedure or any update into retrieving ...

DO NOT WASTE YOUR TIME!

As per the last reviewers. I can confirm SumUp are indeed a poor company to do business with. We had an elderly customer requesting to make payment over the phone but soon realised SumUp did not provide this with the free package so decided to upgrade to the pro to find this also does not allow over-the-phone payments as the service was discontinued a while back. We requested a refund for our subscription to be told "no refunds will be given for purchased subscriptions" we applied for a ...
