B2B2C is a business model where online, or e-commerce, businesses and portals reach new markets and customers by partnering with consumer-oriented product and service businesses. A business developing a product, service or solution partners with another business to use a particular service, such as an e-commerce website, portal or blog. The two business combine forces and promote mutually beneficial products, services and/or solutions.

As an example of a B2B2C model, Business A pays Business B for users, leads or sales generated by Business B's business or website. Business A then uses Business B's channels to locate prospective customers. Business B provides its customers with new and relevant services, facilitating an increased customer base and earned revenue for sold products and services.
