B2B (read as B to B) stands for business-to-business and refers to transactions and interactions between two or more businesses, rather than a business transaction with a consumer as in B2C.
When it comes to the internet, B2B is also referred to as e-biz. This stands exactly for the same thing as B2B, however, all transactions are done over the internet.
B2B transactions correspond to the sale and acquisition of information, products and/or services.
