DIGITAL TRANSFORMATION IN PUBLIC PROCUREMENT AND REDUCTION OF MUNICIPAL COSTS: COMPARATIVE EVIDENCE BETWEEN PORTUGAL AND BRAZIL

Abstract

Digital transformation in public procurement has become an effective strategy for improving transparency, reducing costs, enhancing administrative processes, and strengthening public governance. Portugal and Brazil, although in different implementation stages, have advanced in the digitalization of their procurement systems and in adopting e-procurement platforms, digital catalogues and integrated management tools. This article provides a comparative analysis of digital public procurement models in both countries, focusing on regulatory frameworks, technological instruments, and their impacts on municipal economic efficiency. Based on qualitative and documentary research, findings indicate that digitalization contributes significantly to reduced prices, time savings, risk mitigation, and standardization of procurement processes. The study concludes that Portugal exhibits higher digital maturity, while Brazil shows substantial potential for improvement through the National Public Procurement Portal (PNCP).
