Customer to customer

Marketing concept

Customer to customer markets provide a way to allow customers to interact with each other. Traditional markets require business to customer relationships, in which a customer goes to the business in order to purchase a product or service.

Other types of markets include business to business (B2B), business to government (B2G) and business to customer (B2C).
