Refunds may be issued for invoices originally paid either in full, or partially by credit card.  After a customer is selected, all invoices paid by credit card will be displayed.  Simply check the box next to the invoice to refund, and the credit card transaction will be reversed if the transaction is successful.  

 

Please note that transactions paid with a stored credit card that is currently expired cannot be refunded.  After each checked invoice is processed, a detailed summary of any failed transactions will be displayed.

 

In v3.6.37 the processing of credit card refunds was updated to allow refunds to be made against invoices in a closed period.

Performing Partial Refunds

A new dialog will appear after selecting the invoices to refund which will allow a "refund amount" to be specified for each invoice.

 

Refunds may only be applied to settled transactions.
