The second category is determined by the nature of the participants, such as B2C (business-to-consumer), B2B (business-to-business), C2C (consumer-to-consumer), and C2B (consumer-to-business). E-commerce significantly affects employment, customers, supply chain management, and markets. This book will give thorough insights into the growing field of e-commerce.
