Most of our customers require use to attach our Certificate of Insurance and a copy of the purchase order with our invoice for billing purposes and they want this done every time.

When we setup Recring Invoices there is no way to attach a document so it forces us to send an email after the fact every month with our billing to include these documents making it less efficient and making recurring invoices almost pointless.

Having the ability to attach documents to the recurring invoice just like a regular invoice would solve this problem for us.
