Your store can automatically remove/delete a customers credit card after the card has been charged.
It will not remove/delete a credit card if there is an order is still pending and not charged. This is to prevent cards from being removed/deleted that are still needed on other customers orders that have not been charged yet.
So, what's the difference? A customer (in this case a business) arrives on our store, selects products, pays for them, has them shipped to the address provided, and everything works as usual. Why then do we need to define a different process?
