We just signed up to Paya's credit card processing that's integrated into Sage 50. The actual credit card processing part is great. The problem we're having is the processing screen doesn't allow for receipts to be emailed to the customer. The screen only has "Print Receipt" but no "Email Receipt". It does have a field for the customer's email address, but it does not email a copy of the receipt automatically or give me an option to email one with the press of a button. I have to save the receipt to a PDF and then manually generate an email to the customer.
I hope this can be integrated into the next Sage 50 update.
