eCommerce, short for electronic commerce, is the process of buying and selling goods or services over the internet. It allows businesses and consumers to conduct transactions online without the need for physical stores. eCommerce covers a wide range of business models, including Business-to-Consumer (B2C), Business-to-Business (B2B), Consumer-to-Consumer (C2C), and Consumer-to-Business (C2B). Popular platforms like Amazon, eBay, and Shopify have revolutionized how products are marketed and sold globally.

The main advantages of eCommerce include convenience, a wider selection of products, and the ability to reach a global audience. Businesses benefit from reduced overhead costs, streamlined operations, and access to data analytics for better decision-making. For consumers, it provides the convenience of shopping anytime, from anywhere, with options for easy payment and home delivery. With the rise of mobile commerce (m-commerce) and digital payment solutions, eCommerce continues to evolve, shaping the future of global trade.
