Due to the strong processes of globalization and the dynamics of market changes in the conditions of fierce competition, today's leading companies are forced to constantly develop in order to ensure their efficient operation. It is modern information systems that are responsible for efficient planning and management of company resources and allow companies to expand their business. Information system implementation is a real challenge for managers, operations staff, customers and subcontractors, especially in manufacturing enterprises, so it must be carefully planned and carefully executed. In case of absence of any fixed IT solution, the company can make a decision about the creation of new and individual IT system which meets all its demands. However, such a decision can be made by large companies or groups of companies with the same or similar profile from the point of view of high costs, extended implementation time, as well as high complexity and significant risk. At the present time, there is no economic reasoning for small and medium-sized companies to create a complex IT system from zero. Only one solution is to integrate the current production system (which has been developed throughout years in another company) or system, obtained from the external supplier specialized in the separate field with ERP system that is in charge of managing the other company activities. In addition, comprehensive and actual calculation of production expenditure requires the integration of process management systems, financial systems and payroll systems. Data provided by these systems, including the cost of raw materials consumed, cost of labor force, mass media and equipment, distribution switching mechanisms, cost distribution lists and automatic accounting procedures benefit system users to precisely calculate production costs. Detailed and up-to-date information about the production process and product costs, together with complex logistics information allows us to make reasonable and rational decisions about the future activity of the company, to increase the scale of production of the most profitable products or re-organize some business processes which may lead to a deceleration in the production of low-margin products. Empirical proof shows that there are not any complicated IT solutions that enable production companies to satisfy their needs in terms of logistics, finance, accounting and production process management. Certainly this is related to the fact that even though some procedures like finance, accounting, logistics, reclamation are very alike in different companies at the cost of legal requirements, production processes are individual and peculiar for each one. Thus, it is usually difficult, possibly, to apply certain production process procedures on the available wide-spread IT software.
