Proforma Invoice - how to create 1?

Hi, does anyone here knows how to create a Proforma Invoice?

Here’s the situation, I have a project that’s to be invoiced in stages, how do I invoice that?

Thank you,
Josiah

Hi,

The app doesn’t support proforma invoices however I believe some people use quotes for this instead.

… but why not, Proforma Invoices are widely used, why this limitation?
