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, such as retail sales for a store or service fees for a consulting firm. It is a key indicator of a company's financial health and performance. Operating revenue does not include income from secondary sources, such as investments or asset sales. For example, if a manufacturing company sells its products, the money earned from those sales is considered operating revenue, while any profits from selling equipment would not be included in this figure.
