Hi Daniel Diaz,

You can use Landed cost for this situation.

Landed cost configuration:

1. Activate the landed cost in Inventory --> Configuration --> Settings

2. Create a service product for the landed cost (eg: Shipping charge)

    and tick the landed cost and select a splitting method.

3. Set the selected product category as Real price costing method and Perpetual inventory valuation method.

    also, select stock input and output accounts.

4. Create a landed cost. Inventory --> Inventory control --> Landed costs

Hope this will help you.

Thank you...
