inventory physically on hand at the end of the year. Under the periodic system there is no Cost of Goods Sold
account to be updated when a sale of merchandise occurs.
· If you are using a perpetual inventory system in which there is an inventory record for each individual item in stock,
then you can create a transaction in the inventory system which lists the inventory reduction as a write down, and AX
will create the entry for you (which will still be a credit to the inventory asset account and a debit to the loss on write
down of inventory account). Under the perpetual system there is a Cost of Goods Sold account that is debited at the
time of each sale for the cost of the merchandise that was sold. Under the perpetual system a sale of merchandise
will result in two journal entries: one to record the sale and the cash or accounts receivable, and one to reduce
inventory and to increase cost of goods sold.
4.1.1.5.4 Cost Flows Assumptions
There are three main cost flow assumptions to move the cost from inventory to the cost of goods sold:
1. First In, First Out (FIFO)
2. Last In, First Out (LIFO)
3. Average
Please note that these are cost flow assumptions. This means that the order in which costs are removed from inventory
can be different from the order in which the goods are physically removed from inventory.
4.1.1.5.5 Inventory Systems and Cost Flows Combined
The combination of the three cost flow assumptions and the two inventory systems results in six available options when
accounting for the cost of inventory and calculating the cost of goods sold:
