The abbreviation B2B stands for business-to-business and refers to business transactions from company to company. This distinguishes B2B from the B2C (business-to-consumer) business model, in which the business relationship takes place between a company and its consumers. Whether a business model is B2B or B2C depends in most cases on the industry and the target group. The two can also overlap. If a furniture store not only sells to private customers but also equips companies with office furniture, neither of the business models can be clearly assigned. In this case, it is a combination of B2B and B2C.
