We take credit card payments from our customers and often times we charge their credit card a single amount that applies to multiple invoices. I'd like to be able to send my customers a receipt showing which invoices and POs were paid in that transaction, but there doesn't seem to be a way to do this efficiently and clearly. I can send a sales receipt at the time of transaction, but it only shows the amount paid, not even an invoice number. Is there a method of efficiently sending a notice to a customer as to which invoices were paid and include their PO number in that email?
