eCommerce - USA customers get payment declined
I have an eCommerce website and a high percentage of my customers are from the States. The problem I am having is that when they try to make a credit card payment, the transaction is declined by their bank and they have to call their bank to authorize the transaction. This happens to 60%-70% of my US customers. The bank tells them that it is because their system has flagged the transaction as high risk partly because it is an out of country business. Understandably, a lot of customers don't continue with the purchase and even if they do, it is an awful waste of time and bad customer service. I have maybe 1 charge back every 2 months. Does anyone else experience this? Is it normal? What can I do to eliminate or at least reduce the instances this happens? Any recommendation is most welcome.
