Hi, is there any preferred way to do internal invoicing inside the same subsidiary? I mean for example Department A is invoicing Department B within the same company? Of course you could do an invoice using Department A and a vendor bill for the same subsidiary using Department B or a Journal Entry but is there any feature created for this kind of internal invoicing?

within the same sub - not out of the box but you may want to test creating entities with “representing department” and “department” fields; report on the outcome?
