It would be GREAT to be able to easily email a customer a PAID receipt from the invoice screen. Currently an Invoice marked PAID can be emailed. However, if there was a way to include a copy of their receipt or an attachment that would be nice. If we could select what we wanted to email that would be even better. Perhaps sending a copy of their invoice showing it was paid might not be what a company may want to do. If we could select whether to email the invoice, paid receipt or an attachment that would be the best solution.
