In a B2B model, companies engage in commercial transactions, such as wholesale distributors selling products to retailers or service providers offering solutions to other businesses. Transactions can involve both tangible goods and intangible services and often encompass long-term contracts and agreements. B2B differs from B2C (Business-to-Consumer), where businesses sell directly to consumers. The B2B model is foundational in creating supply chains and significantly contributes to the economy by facilitating commerce between businesses.
