Through this feature, you can also send a thank-you message when an invoice has been paid, or a payment reminder if the due date has passed. This is made possible by the Invoice Status feature. The email type is set automatically based on the recorded invoice status.

Verifying Invoice Email Delivery

If you want to check whether you've previously sent an invoice by email and whether it was delivered to the recipient:

  1. In the Issued Invoices section, click on the invoice number

  2. In the side panel, you'll find the Invoice History section – here you can see the date and time the invoice was sent, when it was delivered, and when the recipient viewed it
