Hello Atul,

In odoo default, the stock valuation will be happening only based on the stock pickings generated from the SO/PO. But from the direct customer invoice or vendor bills, there is no options to trigger the stock pickings.

With some specific customizations, we can easily achieve this functionality. We have to make some custom flow to connect the inventory operations while confirming the invoices/bills. On the customer invoice model, you have to connect with the Operation type of Delivery Order, thereby stock picking and stock moves will be created. The same way you have to implement it on vendor bills.
