In the article "Review on Electronic Commerce", Shafiyah et al. (2013) explains that E-commerce is a business model of buying and selling of products and services through the Internet. E-commerce has been changing economy actives and having a great effect on our daily life. That is a great tool helping customers easily to find the goods and compare the product's price around the world market. In addition, E-commerce also helps business organizations to decrease the cost, increase their profit, and give an opportunity to expand business into the global market. According to Shafiyah, E-commerce is divided into five categories such as B2B (Business to Business), B2C (Business to Consumer), C2C (Consumer to Consumer), Peer-to-Peer (P2P) and Mobile commerce (M-commerce). This report will focus on three primary categories such as B2C, B2B and C2C.
One of the main forms of E-commerce and the one that has been more developed is the Business to Consumer E-commerce. B2C consists in applications that provide an interface from business to their customers directly. The most common example of a B2C application is a retail website featuring the company's products or services that can be purchased by the customer such as Yahoo.com and MSN.com directly. (Shafiyah et al., 2013) state that E-commerce can include electronic transactions in marketing, ordering and paying, after sales service or virtual goods and services, even delivery. Consumers use B2C for the convenience of buying and selling goods over the Web. Companies use B2C to attract new customers, launch new markets and promote products and services (p. 1360).
The second category of E-commerce is B2B (Business to Business), which companies focus on selling to other companies, is the largest form of e-commerce. The price could be negotiated based on the quantity of order (p. 1359). According to Shafiyah, most B2B business models deal with inventory management, distribution management, and supplier management.
