Revenue
Also known as: sales, turnover, top line
Revenue is the total value of goods sold or services delivered to customers during the period. It is the first and highest line on the income statement. Commonly called the top line and the starting point from which every cost, charge, and obligation is deducted to arrive at net income.
Under both US GAAP and IFRS 15, revenue is recognised when control of a good or service transfers to the customer, not necessarily when cash is received. This principle creates meaningful differences between what a company reports as revenue and what it actually collects in cash during the same period, particularly in subscription, long-term contract, and deferred revenue businesses.
The distinction between gross and net revenue matters in practice. Gross revenue is the full amount billed before deductions for returns, allowances, discounts, and rebates. Net revenue is what remains after those deductions and is what almost all income statements show as the opening line.
Revenue is not profit. A company can grow revenue aggressively while destroying value if the cost of generating that revenue exceeds what it brings in. This is why revenue is always analysed alongside gross profit, operating income, and cash conversion rather than in isolation.
Across industries the same concept carries different labels. Turnover in European reporting, premiums in insurance, interest income in banking, subscription revenue in SaaS, and fare revenue in transportation. In every case the underlying meaning is the same: the amount the business earned from its customers by delivering its core product or service during the period.
