Electronic retailing (E-tailing) basically means the sale of goods and services via electronic transaction through the Internet. 

E-tailing can include both business-to-business (B2B) and business-to-consumer (B2C) sales of products and services.

When using e-tailing, companies have to tailor their business models to capture Internet sales, this means building out distribution channels such as warehouses, Internet web pages, and product shipping centers.
