I work for a company that manufactures and sells vehicles. When we talk about a product, we are talking about the vehicle itself; the physical object that the customer will own.
In order to sell these products, we have to produce a lot of other things, such as:
- Service & repair manuals
- Marketing literature
I am looking for a general term or phrase that would describe all of those additional things which must be created for the product, but are not part of the product itself.
