Indeed I think this is a wrong analysis. The assembly service of your example is not invoiced when the goods are shipped but when the service is performed. So there is also another topic which is to have some services sold creating “Work/Task” (I do not think it should be the one from `project` module). And it will be the workflow of those models that will trigger the invoicing.
