How Inventory Loss/Gain is handled in Purchasing

Received 10 items for 8.96, so total is 89.60.

Gain:

Processed this to Bill and change the cost to 7.96, so 10 x 7.96 = 79.60.  Now there is a 10.00 inventory gain on this transaction because you get a better/lower price than what is in Purchase Receipt.

Loss:

Processed this to Bill and change the cost to 9.96, so 10 x 9.96 = 99.60.  Now there is a 10.00 inventory loss on this transaction because you get a higher price than what is in Purchase Receipt.
