How can we process a partial refund through the same credit card that a customer used to pay the initial invoice? 

- In other words, say a customer was sent an invoice for $1200.00 and they paid it through Zoho with our online credit processor, PayFlow Pro...no problems.
- Now, the customer would like to decrease their order and we need to revise the invoice down to $1100.00.
- We issue a credit note for the correction, $100.00.  The customer would like to receive that refund (credit) immediately.
- How do we facilitate that through the same credit card used to make that initial $1200.00 payment?

We don't see a way to do it and have been sending them a paper check as a work around.  This is very cumbersome and leads to issues of things like making the check out to the wrong person or entity and mailing the check to the wrong address.  Many of our payments are made by entity treasurers with product shipping to a separate address, so credit card information is completely different from actual customer contact information.

It would be great if Zoho would be able to fire up a pop-up page with the last used credit card info for use to complete the process of the credit note.

Thoughts and tips are appreciated!
Thanks!
