https://odoobooks.com/en/latest/manufacturing/subcontracting.html is about inserting a subcontracting process to "our" products.

Using the above example, let's say a subcontractor is receiving "sheets" of wood (from the client) and produces table tops. Another example is a bookbinder that receives 30200 printed sheets for the inside plus 1050 sheets for cover and finally produces 3012 books. Each sheet for cover contains 3 covers and each book contains 10 folded sheets.

Is there any corresponding doc about a company that does subcontracting? Company cannot use the materials from one client to produce something for another (obviously...). Company do not know from the beginning how many «table tops» are going to be produced. But an estimation should be noted and "highlighted" (example: About ~3150 books will be produced since the covers are only 3150, given or taken)
