In today's business world, e-business activities of various types contribute significantly to the efficiency of business processes and the recognition of products and services. The Internet plays a very important role in this process, as it offers numerous possibilities for communicating with customers and carrying out commercial activities. As the Internet is rapidly becoming the current platform for conducting business and commercial transactions, it is important for businesses to take advantage of information communication technologies, electronic commerce, mobile devices, and software agents. The Internet has played a vital role in changing the way business is conducted around the world. Due to economic globalization, e-business has become a necessity for companies to remain competitive. You can usually classify most e-business solutions as business-to-consumer (B2C) or business-to-business (B2B). This document will explain the supply chain differences between B2C and B2B and how they differ from each other. Supply chain management, in both a traditional and e-commerce environment, involves the distribution of products, goods and services from the point of production to delivery of the product. final product. Supply chain management, whether related to B2B or B2C retailers, involves the production, storage, distribution and delivery of products and services to consumers and other businesses. Furthermore, the supply chain philosophy ensures that customers receive the right products at the right time, at an acceptable price and at the desired location. Increasing competition, complexity, and geographic scope in the business world have led to continuous improvements in the capabilities of personal computers and made it possible to optimize supply chain performance. Email and the Internet have revolutionized communication and data exchange, facilitating the necessary flow of information between businesses, suppliers and customers within the supply chain (Helms, Marilyn, 2008). B2B supply chain management is slightly more complex than B2C transactions, as B2B wholesalers, distributors, and manufacturers generally work with larger corporate entities. For supply chain management to work in a B2B or B2C environment, the focus must be on providing customers with the highest quality services. This is especially true since in today's economy what companies primarily sell to each other is information, not only in the case of services such as banking and digital applications, but also when the product in question is a physical product. True added value comes from optimizing price and specifications, as opposed to physical transfer of the product (Vasarhelyi, Miklos, 2007).
