Electronic commerce or eCommerce is a term for any type of business, or commercial transaction, that involves the transfer of information across the Internet. It is currently one of the most important aspects of the Internet to emerge.

Business to business (B2B) ecommerce transactions are made between businesses, where a supplier sells in bulk (consumer goods, commodities, industrial) to the purchasing company. We recommend that your B2B ecommerce site have a "B2B login portal" feature on your site. B2B login portals allow you greater control over highly variable details such as:

• ​variable transaction pricing
• figure shipping and logistics for large volumes
• contracts and their entitlements
• any applicable export regulations

Business to consumer (B2C) is where a business sells its product directly to a customer, either directly from a company website or an online marketplace. The purchasing companies that purchase bulk products from suppliers via a B2B ecommerce transaction and then sells those products to directly consumers has then purchased through B2B and sold through B2C.

The business-to-government (B2G) model is a variant of the B2B model where your site is designed with a B2B portal to allow secure communications and procurement transactions with government entities. Such websites are accredited by the U.S. government and have been provided a means for the business to submit their application forms to the government through prior negotiations.

Mobile ecommerce, also called m-commerce or more commonly “mobile,” is a simple modification and formatting of an existing ecommerce website to allow it to be read by any mobile device. Mobile encompasses not only smartphones but also tablets (occasionally referred to as “t-commerce”), with the only limiting factor being the state of current technology.
