My invoicing is a bit odd, it's usually related to receiving payment for specific sheep before I ship them to their new homes so I have invoicing for the animal(s) plus all vet work as an action (and transport if I am paying it on pick-up) and then an action to track that I've received payment before a sheep puts one hoof on a trailer. Since sales of breeding stock are irregular it makes no sense to have a generic invoicing action or project. I may not sell any for months and then I'll sell a bunch over the course of about a month.
