E-commerce involves the buying and selling of goods and services over the internet. It commonly includes online stores, payment solutions, order management, and shipping. The process typically involves a consumer browsing a merchant's website, adding items to a shopping cart, providing shipping/billing details, validating payment, receiving an order confirmation, and having the order fulfilled. Common types of e-commerce include business-to-business, business-to-consumer, business-to-employee, and consumer-to-consumer. While e-commerce provides benefits like convenience and access, it also faces limitations such as an inability to physically examine products.
