Can we have the invoicing app kick back a receipt when an invoice is marked as paid? At this point, even if it just sends ME an email saying invoice was paid, I would be able to forward that to my client. First of all, my customers have to download the invoice in order to see the details. I would love it if they can see some of these details directly in the email that is sent to them. Secondly, we need some sort of receipt. I can only mark as paid from my end and the invoice PDF is never updated with the updated payment. And my clients need this receipt for their own bookkeeping records. Is this feature in the works at all?
