Relatively new customer, at first everything seemed to be fine. I had a payment made to myself by a customer. Payment now on hold (72hrs so far) pending security checks. But I have had no emails or re... See more

Another week, still nothing meaningful from SumUp. They keep sending the same generic “we’ll be in touch” email — some even missing a name, just a template. Complaints were submitted to the FOS a... See more

Terrible customer service. Low quality of hardware. Multiple readers broken down after month or two , same with POS lite. Despite asking to cancel service they’re trying to charge my card for 6 times... See more

Customer service is non-existent - it’s the digital equivalent of screaming into the void. You won’t get updates. You can’t see status. Just an exercise in futility. One can’t help but think th... See more

SumUp. I was offered a cash advance based on my high sales, which I accepted. I was told the funds would be with me within two working days. After hearing nothing, I later discovered that the advanc... See more

Like: it works and the Solo device is wonderful. Dislike: solo device gets blocked, and then cannot be unblocked and requires spending another 100£ on a new device. Air devices fail to connect m... See more

Dreadful. I've used it for our church and for a number of charity events and we've lost so much money because SumUp is so unreliable. It keeps disconnecting from the various smart phones we've p... See more

Like fact that when seasonally closing as we do, can just throw card reader in drawer with no add on costs. Virtual payments a breeze, payment using iPhone nice and handy. Most transactions easy. Pa... See more

After two years trading with SumUp they decided that my business model didn’t fit with their “licence” - whatever that means. Without warning at my busiest time of year they suspended my account. No r... See more
