Thank you for posting, @TomB21403.
An increase to the asset value of an assembly item by either its purchase price or its build costs can change the cost value of your build assemblies.
QuickBooks recalculates the average cost of an item every time you record the purchase of more units of the item. It adds the cost of the new items to the cost of the old stock and then divides by the total number of new and old items.
The average cost of an item is determined by the total asset value of the inventory part or inventory assembly divided by the quantity on hand.
