Answer:
The answer is: Calculates the cost of goods sold each time a sale occurs
Explanation:
A perpetual inventory system is a process of accounting for inventory that utilises real-time data of sales and purchases to update the inventory valuation. This is a more detailed approach to accounting for inventory as the stock on hand and cost of sales can be accurately reflected in the financial records immediately after the sale occurs. The contrast of this is the periodic system which keeps track of inventory on hand by conducting physical stock counts.
