Sales Revenue
Sales Revenue is the total amount of money you bring in by selling your products or services, before subtracting any costs. You calculate it by multiplying the price of each unit by the number of units sold. It's often the very first line at the top of a financial report, which is why people call it the "top line."
Reading it is straightforward: a higher sales revenue means you are selling more, or selling at a higher price, or both. But be careful — revenue on its own does not tell you whether you are making money, because it ignores all the costs of producing and delivering what you sold.
A project manager uses sales revenue to estimate the income a product or project is expected to generate, to compare against costs, and to judge whether a project is worth pursuing. It's the starting point for almost every profitability calculation.
Think of it like the total cash a lemonade stand collects in a day: if each cup sells for $2 and you sell 30 cups, you've taken in $60. That $60 is your revenue — it doesn't yet account for the cost of lemons, sugar, and cups, but it's the money that came across the counter.
Suppose your project delivers a software app that sells for $25 per copy, and in the first month you sell 4,000 copies. Your sales revenue is $25 × 4,000 = $100,000. This tells you the project brought in $100,000 from sales — though you would still need to subtract development and marketing costs to know how much profit you actually kept.
