Business-to-business (B2B) refers to transactions and interactions between two businesses rather than between a business and individual consumers. This model often involves the sale of products or services that help companies operate, such as raw materials, software, or consulting services. B2B companies typically focus on building long-term relationships with their clients, as these transactions can involve larger quantities and higher values than consumer sales. Examples of B2B businesses include wholesalers, manufacturers, and service providers that cater specifically to other businesses' needs.
