I am certain that 'hand-over window' is a local term within a single company and there exists no widely used equivalent, generally, in industry.

Every sizeable company I can think of that I have ever known or have ever dealt with has a 'Goods In' and a 'Goods Out'. Raw materials in and finished product out.

But companies and their functions - and the individual ways in which companies organise themselves - are so hugely varied that there exists, to my knowledge and as far as I have scoured the internet, no commonly used term of the kind that is being sought.
