The cost of goods will be the total cost of goods being sold during the month, it not the balancing figure between the beginning and ending balance. Periodic inventory is the system in which the company does not track individual item movement but only performs physical counts at the month-end.

Moreover, the company is not able to track the daily inventory movement. Under a perpetual inventory system, inventory must be calculated each time a sale is completed. The method of looking at the last units purchased is still the same, but under the perpetual system, we can only consider the units that are on hand on the date of the sale.

Just as described above, the periodic versus perpetual methods differ by how often the inventory count is updated.
