Hi we have the credit card integration with Cybersource. For new customers we propose to use Bill Management module for credit card registration process as client does not want to take the credit card details from customers. However in Bill Management unless there is an existing invoice it is not possible to register a credit card. Our client has a different process, they want to do the registration first without an invoice and complete equipment installation at customer site before raising the invoice.
