We implemented a feature that will generate unique-expiring links when sending an invoice to a client (via email or via URL).
This invoice link will expire:
automatically after 30 days from the due date of the invoice or
after 30 days from invoice creation if the invoice has no due date
Whichever of the two above occurs first. The invoice link will also expire when the invoice is paid.
What to do when the invoices expires
Once the link expires, your client(s) will see an “Expired Document” page and will be able to request a new link to be sent to their email by clicking the "Send new link" button, as shown below.
Once they have done so, a new unique link will be generated for them (URL) or sent to their email address (via email). From there, they can access the invoice via the new link.
