Introduction: The development of technology has led to major changes in the retail sector as well. The global market is experiencing constant growth and is becoming increasingly complex. For this reason, the application of modern retail information technology is increasing so that the retail sector can cope with business trends. Simply put, the implementation of information technology is carried out with the aim of improving service and customer satisfaction. Methodology: Examples from practice in the research part of the paper deal with examples that operate in the Republic of Croatia, and are based on retail (Konzum, Lidl, Kaufland). The research was done by collecting information about these entities through the official website. Discussion: The implementation of information technologies in the business of all three observed entities can be seen from practical examples. Konzum stands out with the first Internet store in the Republic of Croatia that refers to consumer goods and delivery options or pick-up options. While Lidl is constantly introducing new information technologies, most of them have not been implemented in Lidl Croatia, even in the form of pilot projects. Also, the Schwartz Group (Lidl, Kaufland) understands the importance of implementing information technology in all business domains, as evidenced by the development of a software system that competes with large companies such as Amazon. Modern information solutions are finding increasing application in the retail sector. Conclusion: Considering how much each of the examples from practice invests in the development and implementation of information technology, their importance in retail is visible and they support the thesis stated in the introductory part of the paper that companies that adopt opportunities and implement modern information technologies are highly focused on improving customer satisfaction. successful.
