Hello, I'm trying to study a bit Odoo logic about sale orders but I didn't get if exists a kind of "order type" field and I can somehow define that some kinds are not valid to invoice.
For example I need to add "gratuitous loan" document with s/n tracking and shipment but I don't want to invoice it.
Does exists this concept in Odoo?
Many thanks

Thank you. I'm still trying to understand the document logics.
