With the help of expert, scientific relevant literature related to the area of office business and its implementation throughout the Republic of Croatia, it comes to the conclusion that this is one of the most significant reforms and changes that have begun to happen in the entire system, making it easier for citizens - users of services that are necessary for daily needs and participation in a social-political society. As society constantly advances, evaluates and sets new demands, it carries a variety of changes and demands, so the system must be ready to change and meet all the demands of society. Implementation and application of the Decree on Office Business facilitates access to state administration bodies, but also their way of working, which is the basis for a good relationship between citizens and administration. In this way, confidence and security in the efficiency and operation of the administration are strengthened. Easier ways of creating documents, submitting submissions, informing about the ways of creating documents and all the changes that take place in our environment put citizens - users on the ability to easily and quickly accomplish all the needs. The impetuous progress of information technology has enabled reform to be implemented. E-business is a business whose purpose and execution is necessarily performed through electronic-computer technology. Proclamation and sudden development make it easier for the administration and its use. Such a way of doing business is seen as a complement, a step forward for the business world. It also brings together global networking of all parts, system units. This is achieved by strengthening the control and visibility of the state of all the materials of the Republic of Croatia. Which results in the creation of better living conditions and all the more significant shifts in life. Electronic business is the future in all fields, whose full-fledged development is predicted only in the future. The goal is to enable it to move from paper to electronic business in the next few years, and to take the lead in resolving cases. The Republic of Croatia took on the obligation to enable integration with the Croatian public administration into a single European administrative space, deleting the borders of the national systems and allowing citizens to perform cross-border services.
