Business to Consumer (B2C) Sales Model
It is important to remember that most of the current commercial transactions on the Internet, and most of the anticipated transaction growth, occur as business-to-consumer sales. In such cases, the selling business wants to create on the Internet a virtual storefront allowing for anytime sale of products.
Business to Business (B2B) Sales Model
It is also important to remember that most of the earlier models of electronic commerce involved business-to-business transactions using electronic data interchange. In that model, a producer of goods, for example a parts supplier to an original equipment manufacturer, would negotiate via traditional means (meetings, mail, phone, fax) a trading partner agreement providing for terms of ordering, sale, delivery, payment, returns, warranties and the like. This agreement manifested the intent of the parties to contract and to be bound by the terms of the agreement. The mechanics of the transaction -ordering and payment, for example -were then done electronically (originally by proprietary system, and more recently, via the Internet).
