BtoB, or business-to-business, refers to transactions and interactions that occur between two businesses rather than between a business and individual consumers. This model is common in industries such as wholesale, manufacturing, and services, where companies provide products or services to other companies. In a BtoB context, companies often engage in larger volume sales and longer-term relationships. Examples include a software company selling its products to a corporate client or a supplier providing raw materials to a manufacturer. BtoB transactions typically involve negotiations, contracts, and a focus on building partnerships.
