What are some of the most common ways businesses generate revenue? What are the different types of revenue that businesses can earn?Businesses typically generate revenue through four main sources: sales of goods and services, interest income, royalties, and rent. Sales of goods and services is the most common form of revenue, as it is generated when customers purchase a company's products or services. Interest income is generated when a business lends out its capital to another party and earns interest in return. Royalties are earned when a business licenses its intellectual property to other companies, while rent is earned when a business leases its property to another party. These four sources of revenue are the most common ways that businesses generate income and can be used to help them grow and expand.
