It might seem obvious, but in managing a business, it's important to
understand how the business makes a profit. A company needs a good
business model and a good profit model. A business sells products or
services and earns a certain amount of margin on each unit sold. The
number of units sold is the sales volume during the reporting period.
The business subtracts the amount of fixed expenses for the period,
which gives them the operating profit before interest and income tax.
