Supply chain process scenario - Semi finished part invoiced from customer and used as customer owned component

Is there anyone who have already implement the process as follows:

1. We are manufacturing semi-finished part which is ordered by customer and invoiced from customer → Part stays in stock, ownership change in invoicing point customer owned.
2. Semi-finished part will be used for final product with “0” price/customer owned.

Question is, what is the best way to proceed the customer sales without shipping anything and change in that process the ownership from company owned to customer owned?
