Cash discounts are price reductions offered to customers who pay within a specified early payment period. For example, terms such as “2/10, net 30” encourage payment within 10 days by offering a 2 percent discount. This improves cash flow, reduces collection risk, and shortens the accounts receivable cycle. Quantity discounts encourage customers to buy larger volumes. Functional discounts compensate channel members for performing functions such as storage, selling, or distribution. Seasonal discounts encourage purchases during off-peak periods. Internal auditors reviewing revenue and receivable controls should evaluate whether discounts are authorized, accurately applied, properly recorded, and aligned with credit policy. Since the purpose is to encourage prompt payment, Option A is correct.
