Hi,

In Odoo 18, when multi-branch/multi-warehouse is active, the cost price is stored separately per branch. This is different from the sales price, which is usually global for the product unless you set price lists. So when you import inventory or check a product in a different branch, Odoo won’t show the cost price from another branch; it only shows the cost for the current branch you are looking at.

You can import with the branch/warehouse column in your CSV.

Use the inventory valuation or stock quant update to set the cost per warehouse.

Example CSV fields:

Product, Branch/Warehouse, Cost, Quantity

Product A, Main Warehouse, 10, 100

Product A, Branch 1, 11, 50

Hope it helps.
