Enty's Business Glossary:

B2B

B2B (business-to-business) is financial or supply cooperation between two or more businesses such as wholesalers or retailers. B2B businesses are companies that buy products or services and are not their end-user (which means that they will use these products and services to create new ones). The term stands in contrast to B2C (business-to-consumer) and B2G (business-to-government).
