Business-to-business
Business-to-business (B2B) is a term commonly used to describe commerce transactions between businesses, as opposed to those between businesses and other groups, such as business-to-consumers (B2C) or business-to-government (B2G). More specifically, B2B is often used to describe an activity, such as B2B marketing, or B2B sales, that occurs between businesses and other businesses.
The volume of B2B transactions is much higher than the volume of B2C transactions. The primary reason for this is that in a typical supply chain there will be many B2B transactions involving subcomponent or raw materials, and only one B2C transaction, specifically sale of the finished product to the end customer. For example, an automobile manufacturer makes several B2B transactions such as buying tires, glass for windshields, and rubber hoses for its vehicles. The final transaction, a finished vehicle sold to the consumer, is a single (B2C) transaction.
Etymology
The term "business-to-business" was originally coined to describe the electronic communications between businesses or enterprises in order to distinguish it from the communications between businesses and consumers (B2C). It eventually came to be used in marketing as well, initially describing only industrial or capital goods marketing. Today it is widely used to describe all products and services used by enterprises.
