E-business involves conducting business processes online and includes activities like buying and selling products, customer service, and collaborating with partners. E-commerce specifically refers to online transactions, usually business-to-business, business-to-consumer, or consumer-to-consumer. While the terms are sometimes used interchangeably, e-business encompasses both external e-commerce activities and internal processes like production and inventory management. E-business strategies aim to improve efficiency and productivity through integration across different business systems, but they are more complex to execute than e-commerce strategies.
