B2B2B, also known as business-to-business-to-business, refers to a business model in which a company sells its products or services to another business, which in turn sells those products or services to yet another business. This type of transaction involves three parties, with the ultimate goal of providing goods or services to the end consumer. B2B2B is often seen in industries such as manufacturing, where multiple suppliers and distributors are involved in the production and distribution process. This model allows for a more efficient and streamlined supply chain, as well as the potential for increased sales and partnerships between businesses.
