I have a client that needs to be able to take credit card information but not process it when it's taken. They ship a lot of their product via freight with multiple carriers. They want to be able to calculate the shipping after receiving the order and then bill the credit card using their in house processing machine. They also need the ability to accept a PO # (Purchase Order #) instead of a credit card, it their client want's to use it instead.
I would appreciate any help.
