I am using Odoo 18 and managing inventory valuation for imported goods. I want to accurately distribute additional costs (such as shipping, customs, and insurance) across my product costs using the Landed Costs feature.

I have already:

Enabled Landed Costs in Inventory > Configuration > Settings.  Created a Vendor Bill for extra costs (e.g., shipping fees).

 Defined a Landed Cost type and assigned a cost split method (By Weight, By Volume, By Quantity, or By Current Cost).

However, I am unsure how Landed Costs affect accounting and stock valuation and whether it updates the cost of goods sold (COGS) automatically.
