Revenue is the total income generated by a business through its regular activities, primarily the sale of goods or services. It is a key financial indicator, reflecting the ability of a business to generate income from its core operations. Revenue can come from various sources, such as product sales, subscription fees, service charges, or licensing agreements. It is typically reported on a company’s income statement and serves as the foundation for calculating profitability. Healthy revenue streams are essential for the sustainability of a business, as they cover operating costs, enable growth, and contribute to overall financial stability.
