I have used it for clients from the UK, US and Canada
to great satisfaction at both sides for a couple of years. It saves me up to 5% per
transaction, and it saves the buyer 2.5% that Paypal charges for the conversion.
It is only for international payments, not domestic. The buyer transfers the amount to a local bank account of transferwise. Then the receiver gets his money
from a transferwise account in his home
country. This avoids the intransparant and sometimes very expensive bank conversion fees.
