Which of the following best measures the total revenue generated from customers after deducting returns, allowances, and discounts over a specific period of time?

Calculate Net Sales using the formula: $\mathrm{Net}\mathrm{Sales}=\mathrm{Gross}\mathrm{Sales}-\mathrm{Sales}\mathrm{Returns}-\mathrm{Sales}\mathrm{Allowances}-\mathrm{Sales}\mathrm{Discounts}$

Compare Net Sales to other financial metrics: Accounts Receivable measures amounts owed by customers, Operating Income reflects profit after operating expenses, and Gross Profit is revenue minus cost of goods sold. None of these directly measure revenue after deductions like Net Sales does.
