You use the first in first out method where you assume the first item you buy is the first item you sell - i.e. items are in a queue You buy the first item for 100 and the second item for 200 - you then sell 1 item for 400. At balance date you would have: Sales of 400 Cost of Sales of 100 Profit of 300 Inventory of 200.
