You cannot even change the order of items in checkout making taking payment awkward ### 1/5 — Appalling *2026-08-12, version 3.110.0* Having been a customer for several years I have now left. There is no customer service, just an endless funnel that is no help whatsoever. Emailed them, phoned them, used the chat bot, used an online agent who disappeared mid chat after I had found all the information she asked for. Customer service should be anything but difficult. What a fiasco. ### 1/5 — Terrible *2026-08-10, version 3.109.0* Do not use ### 1/5 — Terrible customer service *2026-08-10, version 3.109.0* Every time I try and make an online payment it gets declined, although there is plenty of money in the account. All I get from customer Service is maybe there are insufficient funds in your account!. ### 1/5 — Awful *2026-08-05, version 3.109.0* I signed up to SumUp just over 12 months ago and to say the least I’m very unimpressed. Initially service was ok but recently I’ve had problems accessing my money, all there is is an AI bot, an automated system you go around endlessly and no help whatsoever in getting your own money. I currently have pennies in my bank account and thousands in my SumUp account that I can’t access because they don’t send a verification code. My card reader also overheated and melted and it took several days of talking to a bot trying to get a replacement. Avoid. Update I am now even more frustrated, after finally being connected to a human via online chat apparently I can not access my money. You can not access from an iPad only a phone and as my phone is old I can not get the app. Their suggestion is to get someone else to download and link it to my account?? Wtf? The reason given for not being able to use my iPad is that it’s not secure, oh but getting Brian down the road sounds really secure. Avoid Avoid Avoid ### 1/5 — Hold up not sum up *2026-08-05, version 3.109.0* Zero chance of a resolution and pay for the privilege please be careful as your money is held under either r2 months or refunded back to customer leaving you high and dry Under the impression of the law Wake up sum up ### 1/5 — Rubbish. No direct means of support *2026-08-03, version 3.108.0* Rubbish. Cannot find any way of contacting support other than within App/ chat but never get a reply ### 1/5 — Mr *2026-07-30, version 3.108.0* Uk’s Worst customer service Ever gone through in my life no human agent available ai can’t understand the problem no email response or calls response go with some other terminals. ### 1/5 — Worst bank *2026-07-27, version 3.108.0* Don’t use your money will get locked ### 1/5 — Support is very poor *2026-07-27, version 3.108.0* 3 months in to verification process, as change of director, endless issues, support have no clue what they are going or advising ### 1/5 — Worst for business *2026-07-27, version 3.108.0* SumUp is worst account and card payment service I ever use it will just hold your account and then you will not be able to connect with any support and support are unhelpful ### 2/5 — Stop flashing ads when I want to use the app! *2026-07-22, version 3.107.0* I’m running a business here. This old review is even more true today. Pushing their apparently indispensable extras at every turn. So tiring. ## Most critical reviews (10 lowest-rated) ### 1/5 — Be careful with customer service *2026-09-04, version 3.113.1* They give you the wrong information which cost you money. Not helpful to small businesses. ### 1/5 — STAY THE HELL AWAY! *2026-09-02, version 3.113.0* I was warned before to stay away from Sumup but I learned the hard way by still signing up😂 I received a £699 payment into my business account. My first ever payment on the account & straight away blocked. My account shut down & no response about releasing my money. Stay away from this scam bank! ### 1/5 — Won’t let me sign in the link has no verification button to sign in. *2026-08-30, version 3.112.0* No verification button ### 1/5 — Terrible *2026-08-30, version 3.112.0* DO NOT EVER use this service if you run a business, they will close your account randomly and remove all access and their customer support is a chat bot that won’t let you speak to anyone unless you log in but you physically can’t log in. So impossible to talk to someone and resolve issues. Avoid at all cost. ### 1/5 — New businesses stay clear *2026-08-27, version 3.112.0* When we first set up with sum up, a representative from the sales team would be happy to call you and answer any questions. The moment you become a customer, you get diverted to an AI bot with no one able to give you a call back. The system has crashed on countless occasions during busy periods resulting in significant revenue losses. When trying to contact sum up to rectify this you get diverted to an AI bot with no resolution. We have lost out on hundreds of sale within our first 2 months due to the unreliability of the system. I would advise any new business to stay clear. ### 1/5 — Deleting infu *2026-08-25, version 3.112.0* I am having trouble deleting my information on the app and getting no help!! ### 1/5 — Worst app to communicate *2026-08-23, version 3.111.0* So difficult to understand and also so many verifications takes long time to send money and process is so difficult. I'm closing my account ### 1/5 — Terrible *2026-08-22, version 3.111.0* Luckily I tried with one pound it did not transfer to me and just stole money from the other person do not download this scam ! ### 1/5 — Avoid can ruin your business *2026-08-19, version 3.111.0* Held a genuine transaction for no good reason from my client, after days of radio silence I finally received an saying I could not have the money and it will be held for two months. Totally destroyed my business. ### 1/5 — Just go with Square *2026-08-15, version 3.110.0* Tried this for a year, have the solo reader. Everything is too buggy and there’s far better POS platforms with more customer support and resources available. I’m on square and it’s been 1 day and i’m already happier with the switch. Waiting on my last payment invoice through sum up and never touching again!! ## Most praised reviews (10 highest-rated) ### 5/5 — Business *2026-09-04, version 3.113.1* 5 ### 5/5 — Recomendação *2026-08-31, version 3.113.0* Tenho utilizado a SumUp há algum tempo e, até ao momento, a minha experiência tem sido bastante positiva. Não tenho enfrentado nenhum empecilho durante a utilização dos serviços, e tudo tem funcionado de forma simples e eficiente. Agradeço à SumUp pela qualidade do serviço e espero que continuem a manter este nível de compromisso com os seus utilizadores. Recomendo pela minha experiência até agora! ### 5/5 — Card Reader *2026-08-26, version 3.112.0* Excelente herramienta ### 5/5 — Plans for Botanical Ilustrations *2026-08-06, version 3.109.0* My Role ### 5/5 — Sumup for small business *2026-07-29, version 3.108.0* In my opinion I have founded that my Sumup account has been precise, functional, easy and affordable. My art does not require a daily sales output and effort because I don’t operate that way. I can produce invoices when needed. I am not technically smart. But I can manage Sumup! Quetarshe Textile Design Studio ### 5/5 — So convenient up and running in 5mins! *2026-07-26, version 3.107.0* Have used this with the school fairs in the past. This time my kids wanted to do a lemonade stand which is of course ruined by a cashless society. That is of course until you have sumup they made a killing, 90% of which on card ### 5/5 — Love it *2026-07-25, version 3.107.0* More sales ! No pierdo ni una venta desde que tengo SUMUP. Pequeño, versátil y fácil de usar. ### 5/5 — Easy to Navigate *2026-07-20, version 3.106.0* I set it up impromptu and I was glad I did. Made payment easy for me. ### 5/5 — Sistema de cobro *2026-07-17, version 3.106.0* Muy bueno y eficiente ### 5/5 — Taxi driver *2026-07-14, version 3.106.0* Good service --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
