Revenue vs. Expenses
Revenue is money your company earns from conducting business. If you owned an ice-cream stand, for instance, revenue is what you get from customers who buy ice cream. Expenses are the costs you incur to generate that revenue. The ingredients you buy to make the ice cream, the wages you pay your employees, the rent and utilities you pay for your stand -- these are all expenses. To remain viable, a company's revenue must exceed its expenses.
