Understand the difference between perpetual and periodic inventory systems. The perpetual inventory system continuously updates inventory records and the Cost of Goods Sold (COGS) account with each sale or purchase. The periodic inventory system updates inventory and COGS only at the end of the accounting period.
Analyze the first statement: 'Both systems require a physical count of inventory at the end of each month.' This is incorrect because a physical count is typically required only under the periodic system to determine ending inventory and COGS. The perpetual system tracks inventory in real time, but a physical count may still be done periodically for accuracy.
Evaluate the second statement: 'Under the perpetual inventory system, the Cost of Goods Sold account is updated continuously with each sale.' This is correct because the perpetual system records COGS immediately after each sale transaction.
Assess the third statement: 'The perpetual system does not track inventory purchases in real time.' This is incorrect because the perpetual system does track inventory purchases and updates inventory records in real time.
Review the fourth statement: 'Under the periodic inventory system, the Cost of Goods Sold account is updated after every purchase.' This is incorrect because the periodic system does not update COGS after every purchase; instead, COGS is calculated at the end of the accounting period using the formula: \( \text{COGS} = \text{Beginning Inventory} + \text{Purchases} - \text{Ending Inventory} \).
