Public procurement has acquired new dimensions in recent decades, going beyond the elementary satisfaction of certain needs. Public procurement connect to public policies through its horizontal nature. In present study, public procurement is perceived as an important demand-side policy instrument that can effect both the speed and the direction of economic development. A key argument supporting the view of public procurement as an important policy instrument is that they accounts for about 14% of EU GDP. At the same time, governments frequently overlook procurement as a policy instrument (and demand-side tools in general). The study of public procurement as a policy instrument, given their proven market effect, merits further analysis. Hereof, this research is focused on exploring strategic procurement approaches for economic development. Actually, through public procurement, governments can contribute to the development of growth-generating economy sectors in the role as an important lead consumer by setting standards and exacting superior performance.

The development of telecommunications and computer science has created a favorable climate regarding the increased development of electronic communication and has also led to an increase in the number of electronic documents that are being generated, stored or transmitted via computer networks. These documents are valuable but prone to manipulation by unauthorized persons that consequently leads to a need for enforced protection of the information contained in those documents from unauthorized third parties.
Digital signatures provide required validation and verification of electronic documents and represent a series of units and zeros obtained from a particular digital signature algorithm. The article emphasizes the practical application of digital signatures in the electronic system for public procurement by introducing the manner of the electronic signing of documents depending on the application software used by users in the Republic of N. Macedonia.
