Business are in the business of earning income.

For example, owners must receive income reports every year, and the government requires corporations to pay taxes on annual income. Within the business, management uses financial statements – prepared every month or more often to monitor performance. Because of these demands, a primary objective of accounting is measuring net income in accordance with generally accepted accounting principles.
