revenue
/ REV-uh-noo /
Think about the cash register at a busy bakery on a Saturday. Every croissant, every loaf, every coffee that someone pays for adds to a running total of money the bakery earned that day. That total — the value of everything the business sold to customers — is its revenue. It is the very first and biggest number on the income statement, which is why people call it 'the top line'.
Precisely, revenue is the amount a company earns from its main business activities — selling goods or providing services — over a period. Crucially, revenue is counted when it is earned (the goods are delivered or the service is performed), not necessarily when the cash arrives. If a consultant finishes a 5,000 project in December but the client pays in January, the 5,000 is December's revenue. Revenue is usually shown 'net', meaning after subtracting customer returns and discounts, so it reflects what the company actually expects to keep from sales.
Revenue matters because it measures the scale of a business — how much demand it is actually capturing. But revenue alone says nothing about profit: a company can have huge revenue and still lose money if its expenses are larger. A common beginner mistake is to treat revenue as if it were profit or as if it were cash collected. It is neither; it is simply the gross inflow from doing business, sitting at the top of the statement waiting for all the costs to be subtracted below it.
An online shop ships 1,200 orders averaging 40 each in March; its March revenue is 48,000, recorded when the goods are shipped — even for the customers who paid later on credit.
Revenue is earned at the point of sale, not at the moment of payment.
Revenue is the top line, not the bottom line: a company with rising revenue can still be unprofitable, because profit only appears after every expense has been subtracted.
