Most companies in the world have implemented on-premises ERP systems to support business resource management. However, rapid advances in technology and the development of cloud computing have enabled the development of new ways of implementing ERP systems. Companies can now decide between traditional, on-premises implementation, cloud system implementation, or they can opt for a hybrid model of the ERP system that integrates the best features of the previous two models. Each of the offered models has its advantages and disadvantages, and it is up to companies to choose the solution that best suits their specific needs. The subject of the thesis are cloud ERP systems. The aim of this paper is to provide a detailed insight into traditional, cloud and hybrid systems, describe their impact on the business and present the offer of cloud models on the market and on the example of one medium-sized company, describe the current situation and make a proposal for the transition. As part of thesis a research has been conducted using the method of a questionnaire with a closed type of question among ten employees of the Tvonica mreža i ambalaže company. The goal was to evaluate their satisfaction with the current ERP system and their knowledge of cloud computing. A semi-structured interview with the factory director was also conducted in order to get first-hand information of the current situation and their considerations about cloud transition. The results obtained showed that employees are partially satisfied with the current system, that the company is considering moving some functions to the cloud, and that employees have knowledge of cloud systems, which creates a good basis for transition.
