Competitive advantage refers to factors that allow a company to produce goods or services better or more cheaply than competitors. These factors generate more sales and superior margins. Competitive advantages come from various sources like cost structure, branding, quality, distribution network, intellectual property, and customer service. They allow companies to achieve higher profits compared to rivals and generate value. A competitive advantage distinguishes a business and makes customers prefer its products over others.
