E-commerce businesses are companies that sell products or services online. They operate through websites or mobile apps, allowing customers to browse, select, and purchase items from the comfort of their homes. Popular examples of e-commerce platforms include Amazon, eBay, and Etsy. These businesses can range from large retailers to small independent shops. E-commerce can be categorized into different types, such as B2C (business-to-consumer), where businesses sell directly to customers, and B2B (business-to-business), where transactions occur between companies. The growth of e-commerce has transformed shopping habits, making it easier for consumers to access a wide variety of products globally.
