E-Commerce websites are online portals that facilitate online transactions of goods and services through means of the transfer of information and funds over the Internet. In the early days, e-Commerce was done partially through emails and phone calls. Now, with a single website, anything and everything that a transaction needs, can be executed online. There are different e-Commerce websites for every field. The most common type is retail selling, but there are many others too, like auction websites, business-to-business services, music portals, consultancy websites, finance management websites.
