No. We are based in Spain, in the Euro zone, but most of our receipts and our payments (to countries in Africa) are in US dollars. Our research has revealed if we were paid by credit card not only would a commission fee be incurred, but any payment would be credited in euros (even if we had a US dollar Paypal account!).
As a result we only accept payment by wire (bank) transfer. This has always been efficient, very economical and simple to do. We have two different accounts that you can wire money to. One is our bank accounts in Spain. Another is using our Transferwise account. This system is even more efficient and economical for the payee, as the transfer is a domestic one paid into an account in your country of residence.
