I run a SaaS business with almost all of the customers in the US from Germany, using a German stripe account. Credit card support is very limited, as any transaction will look like an international charge to the credit card vendor. This results in two situations that happen quite often: the card gets declined flat out (any kind of debit card, Discover, some AmEx) or the customer has to call their bank to allow for the charge. I had to build a customer support automation to help the customers understand that it’s not their problem. It is a bearable problem, but moving the accounts over to the US would reduce this friction, which happens at one of the most relevant times for retention.
