How to create AR invoice before we ship confirm the sales order?

Summary:

We have a requirement where the client wants to generate actual AR invoice (with invoice number) and paste it on goods before it is shipped. This is needed for compliance in few of the countries where they operate.

We want to avoid doing ship-confirm in system before the actual physical ship-confirmation for the purpose of generating invoice, as this may lead to certain exception and compliance issue.
