I'll throw this in..... I'm an internet trader and we sell 99% of our goods by Credit/Debit card. However, every now and again we get a customer who hasn't got a card and whats to pay by IBAN.
This whole process is a nightmare. Depstie being very clear sometimes the sending bank will take their comission off the amount that should arrive. Of there'll be an intermediary bank who takes a bit of comission on the way! In addition, the IBAN numbers seem to change every few months so what worked last month may not work now. Finding the money can be a nightmare, plus if the arriving amount is not what was required, a followup payment will incur a bank charge again. So an amount thats lost a couple of pounds on the way, will then find a fixed charge added to that transaction of, say another 10 euros on a nominal payment. And dont get me started on refunds........
