The most economically advantageous offer within the public procurement process is the selection of the offer that provides the best ratio between price and quality. The goal of public procurement is to ensure the best value for the money invested and at the same time to encourage competition among bidders, as well as to promote optimal solutions. Ultimately, such an approach not only contributes to more efficient use of public resources, but also encourages market competition. In the Republic of Croatia, public procurement is regulated by the Law on Public Procurement, OG 120/2016 and OG 114/2022, and with other legal regulations, such as the Law on Concessions, the Law on Public-Private Partnerships and the Law on the State Commission for Control of Public Procurement, and with by-laws, such as the Ordinance on Procurement Documentation and Tenders in Public Procurement Procedures, OG 65/2017 and OG 75/2020, Ordinance on Electronic Complaints in Public Procurement, OG 101/2017, OG 19/2023, Ordinance on procurement plan, register of contracts, prior consultation and market analysis in public procurement, OG 101/2017 and OG 144/2020, and Ordinance on training in the field of public procurement, OG 65/2017. It is also important to point out that the Republic of Croatia, as a full member of the European Union, harmonized the legislative framework in the field of public procurement with the acquis of the European Union, which ultimately contributes to a legal and principled public procurement.
