The subject of this work is documentation in public procurement procedures. Public procurement is a complex and layered system that carries out the procurement of goods, works and services in a professional and serious manner with the aim of concluding a contract between the client and the tenderer. In other words, the state, as a broader term, contracts business with the private sector. The special feature of the public procurement system is that it formally implements procedures for contracting relationships, which contributes to avoiding favoritism and, ultimately, conflicts of interest. The goal is to meet financial expectations, value for the lowest price. In order for the formal nature of all public procurement procedures to remain efficient and balanced, the emphasis is on quality preparation of all necessary documentation, requirements for initiating public procurement, criteria for selecting bids, and finally showing the importance of public procurement reports. The aforementioned activities ultimately result in the success of the involved parties and the conclusion of quality framework agreements and contracts, which are the result of transparent, fair and equal market competition for all participants. The work will also mention the compliance of the legislation and implementing regulations of the Law on Public Procurement of the Republic of Croatia with the legal norms of the European Union, of which the Republic of Croatia is an equal member.
