When people buy and sell things over electronic systems, like the Internet and other computer networks, they are called “e-commerce.” With the widespread use of the Internet, the amount of trade done electronically has grown a lot. The use of commerce is done this way, which leads to and draws on new ideas in electronic funds transfer, supply chain management, online marketing, electronic data interchange (EDI), inventory management systems, and automated data collection systems.

Web-based electronic commerce is the most common way to do business today, but it can also use other technologies like e-mail to do business.
