Full automation for invoices just like ticket automation.

I.E. "When Invoice is created ---> Add Inventory Item to Invoice(Card Processing Fee)"

"When Invoice is created ----> Set ticket to x"

"When invoice is edited ----> Send Email to Technician"

"When invoice is paid/paid online ----> Auto Resolve Ticket"

Just something like ticket automation would be awesome for simple automation to make invoicing easier.
Thanks!
