I run my business on a part time basis, around other commitments and also live in a rural village and even in nearest town there is no access to banking cash. So my SUMUP card reader is great for when I provide therapy services or sell my products at Fairs. I have already referred the Basketball Association members to get these to help gathering annual membership subs easier. As the audit info sent to your email is brilliant too.

As a small business - my sum up machine is a god-send! It’s SO easy to use, makes selling at markets a breeze, and was really reasonably priced to purchase. Reviewed on: 23rd January 2020

Scam

I was a customer of SumUp's client, a bike rental shop in Spain. I was due a refund of a security deposit of 100 EUR on 9/11/2019. I got their sms with link that the refund was made, but it never arrived. SumUp took 100 EUR from the shop and then charged back the original 114 when I asked my bank to investigate. So the shop list 214, I lost 100 Eur. The issue is still pending, SumUp does not reply. Reviewed on: 21st January 2020
