Dear
I would like to order SumUp (reason: third point so that people do not have to do QR payments and they do not see my private address appear in their transactions). People pay me £75 per therapy session. Until now, I have always issued an invoice here (many people ask for this and I send it to them). If I purchase SumUp, 1.69% per transaction will go to them. How does this work for my own invoices? Via credit note or similar? Or perhaps you have experience with SumUp yourselves: do you receive an overview, invoicing or similar?
Thanks in advance!
