Customer account payment process
When customer accounts are set up within the system, payment processing for orders belonging to these customer accounts differs from that for the General Payment Process.
A customer account can be set up in the system by setting the Customer Account Maintained Internally flag for the payment rule, and setting the account limit for that customer account. For this functionality to work effectively, the Hold To Be Applied Due To Insufficient Funds In Customer Account rule should be configured. Besides this, the deprecated functionality of hold types should not be on.
