Answer: a physical inventory count should be taken at least annually
Explanation: That an inventory is perpetual does not discount the need for taking physical inventory at least once a year. This is important because it helps in the identification of shrinkage or shortages and to also test the accuracy of the perpetual records under use. Now, a perpetual inventory is a kind of inventory that tracks and records continuously, items as they are added to or subtracted from the inventory thus keeping it updated and aids in keeping the track of the cost of goods bought and sold.
