Sum up was fine until it updated the card machine and added VAT. Caused numerous problems and I had to give customers cash back! Card machine frequently declines cards and stops working, then updates when we are extremely busy! Now cannot log into my own account to access contact from SumUp as one card machine keeps declining cards including my own as a test! Not a happy customer!

Sumup card reader no longer reliable

I’ve been using Sumup for my small business for several years. Even bought a second card reader for my husband to use at busy events. I have , in the past, been really pleased with our Sumup Air readers with no problems. But during the last 10 days we had stalls at 2 big agricultural events, where - in previous years Sumup has worked really well. However at both these events this year our Sumup readers just wouldn’t work. Took advice, reset the reader - as per instructions - eventually ...

POS stay away from SUMUP

Sold a system over the phone, which would suit my needs as a small buisness, table service, pay at table etc, Problem being, who walks around with a 9" Ipad taking orders at a table? Also if your taking orders at the table on the ipad how can you use it as a till system? So asked about adding another ipad, ipad mini... Boooooom £359 extra, then another £300 for another licence because they can't work together "apparently" then to find out you can't actually print recipes/till transactions ...

2 months on

2 months on, still not refunding me for a faulty device. Keeping fobbing me off. The call centre is India and I understand hindhi, when ever I ring they are more interested in their tea and fritters. Thanks for replying Sumup team, I have replied to the email from your support team with proof of postage, they have taken no action and still no refund. They keep saying the email I replied from doesn’t exist in your system and have left me in limbo.

So far so 👍

So far so 👍. As a small business cash flow is key and sumup pays me by lunchtime each day. Dashboard and app are easy to navigate and tbh I get a better service from them than my bank ! Trying to switch to their bank but my old bank keeps denying my request...Probably because they need the bank charges that I pay for no service. Sum up all the way for me...no more greedy contracts °
