Operating revenue refers to the income generated from a company's primary business activities. This includes sales of goods or services that the company offers to its customers. For example, a retail store earns operating revenue from selling products, while a software company earns it from providing software solutions. Operating revenue is a key indicator of a company's financial health, as it reflects the effectiveness of its core operations. It is distinct from other types of revenue, such as investment income or interest income, which come from non-operational activities. Understanding operating revenue helps stakeholders assess a company's performance and growth potential.
