E-commerce is the broad term used for the process of buying and selling of physical goods over the internet. The most profitable and visible segments of the e-commerce market are business-to-business (B2B) and business-to-consumer (B2C). When goods are purchased and sold online between two businesses, it is defined as B2B commerce. When online transactions take place between a business and a private user or consumer, B2C commerce is the term that best describes the process.

In recent years, consumer-to-consumer (C2C) players have gained in popularity driven by big names such as eBay and Taobao, the Alibaba Group’s C2C platform.
Most recent developments in worldwide e-commerce have taken the market towards a more mobile direction. Today, in addition to online platforms on desktop and mobile devices, many e-commerce players and online retailers sell their products via mobile shopping apps.
