I'm looking to create a simple pre-populated invoice that goes to the workflow owner after the contract is signed. I want to create a document that doesn't go out at all to the counterparty, but is sent to the workflow owner as an e-mail attachment after the contract is signed (ideally it would even be in the Archive stage since we are looking to pull in information to a completed record at some point, but don't have that in place yet). What is the best way for me to (1) set up a document that never triggers for an actual contract and is only to be used for this e-mail, and (2) How can I set up an e-mail with this document as the attachment at the latest stage possible? Appreciate any thoughts on this topic. Thanks.
