I depend on the ability to send a Proposal + Contract + Invoice all in one link/email.
It significantly reduces slow turn arounds on deposits if clients are immediately shown the invoice for the agreement they just signed and are prompted to pay.
This is different than approving and sending the invoice via email immediately because the invoice is included as part of the webpage a user is already on. This feature request is for a similar functionality to the Proposals feature in Dubsado, Honeybook, and Plutio.
