With the development of new technologies, new, complex, personalized and often smart products are emerging in different markets. In order to produce this kind of products successfully and increase efficiency in the production of current ones, companies must adapt to new working conditions and new environments. The smart factory concept is the most important product of Industry 4.0. and represents a production mode that is optimized. Using the various tools created for the fourth industrial revolution opens the possibility of building a modern facility or transforming a traditional one into a facility that meets all standards. Production that meets Industry 4.0 standards is achieved by connecting the virtual and physical worlds through the application of new, digital technologies. Digital technologies include: robotics, Big data, IoT systems, artificial intelligence, M2M communication and more. Successful digital transformation requires several steps involving the implementation of different systems. One of the most important steps is certainly vertical integration, which is the topic of this paper. This paper demonstrates the use of ERP systems for enterprise data collection and the opportunities that are created by improving the processes themselves. More specifically, the GoSoft ERP system at Metalprofit and PIMS Elektro Oprema is on display. Given the amount of data that is generated on a daily basis, without the use of software, production would be extremely difficult or even impossible. With this in mind, GoSoft is upgraded almost daily to meet the growing demands of production. This paper proposes and analyzes potential upgrades related to machine integration and optimization of the planning and production management process.
