We have an "Invoice Delivery (Unpaid)" and "Invoice Delivery (Paid)" invoice template. This has led to some confusion lately where people assume that the Paid version is sent when the invoice is paid so that the client will get another copy of the paid invoice. However, that's not how it works, we simply use one or the other depending on whether the invoice is paid at time of delivery.

These people have requested an option to re-queue the invoice for delivery once paid, saying that they want the customer to receive another copy of the invoice once it is paid, which shows the paid watermark and/or transaction.

Under Settings > Company > Billing/Payment, under "Invoice Services Together" add a new option (unchecked by default) called "Requeue Invoices for Delivery Once Paid". Add this option to Client Groups also.

If this option is enabled, when an invoice is closed (paid in full), we will re-queue the invoice for delivery, which will cause another copy of the invoice to be sent to the client with the PAID watermark and/or transaction history. on the PDF.
