why is this not possible? it seems like a very basic need for self-employed people. I'm having the same issue and its infuriating that I can't just create an invoice without having to email it. Sometimes I need to send an invoice to multiple parties in which its necessary for someone to approve the invoice within a group email chain. Which service am I supposed to use as someone who is self employed in order to be able  to achieve saving an invoice without emailing it?
