Partial adjustment of inventory cost at one inventory location

Suppose the following:

*Item1 is purchased at $10/each for 10 units, with a total inventory cost of $100, received into Location1
*Perform inventory transfer to Location2, incurring $10/unit in additional cost ($20/each now)
*Location1 should have Qty 5, total cost $50
*Location2 should have Qty 5, total cost $100

What’s correct way to permanently change the cost of the 5 units at Location2? Meaning if I sell units from Location2, the item cost should reflect $20/each, not $10 each.

When I purchased the 10 units, I can simply fill in the freight cost on the Purchase Invoice and let Manager allocate the cost. I’m looking for a way to do the same on existing inventory as there isn’t an option to add additional freight cost when doing inventory transfer. Currently, I’m simply billing the additional $10/unit cost as a one time Purchase Invoice, which distorts the cost.

Inventory transfer doesnt affect the cost of inventory, you are only transferring goods from one inventory location to the other

Yes, I understand that the inventory transfer is strictly for moving inventory. Do you have any suggestions on how I can update the inventory cost for the moved items?

If these items were distinctly identifiable and have different cost than other similar items, then you can use a Production Order for that purpose.

The items are not distinct, but they are trackable. This is for item shipped into Amazon fulfillment that will only be sold from that inventory location.

I think your suggestion will work, I just need to record the items with a separate item id.

Thank you.
