Public procurement is a core function of local governance because it converts public funds into goods, services, and infrastructure needed for community development. At the barangay level, procurement is expected to comply with Republic Act No. 9184 and its implementing rules, particularly in relation to planning, supplier selection, documentation, transparency, monitoring, and accountability. This study assessed procurement procedures and compliance with Republic Act No. 9184 in selected barangays of Isulan, Sultan Kudarat. Using a descriptive mixed-methods design, data were gathered from forty-three (43) barangay officials, Barangay Bids and Awards Committee members, secretaries, treasurers, and procurement personnel through survey questionnaires, interviews, and document review. Quantitative data were analyzed using frequency count, percentage distribution, and weighted mean, while qualitative inputs were used to contextualize and synthesize the findings. Results showed that procurement practices were strongly observed, with an overall mean of 4.44, particularly in documentation, supplier selection, and method selection. Compliance with Republic Act No. 9184 was also rated strongly, with an overall mean of 4.50. However, budget limitations and insufficient procurement training remained key constraints affecting procurement efficiency. Respondents strongly supported standardized procurement procedures, stronger monitoring and evaluation, digital procurement tools, and continuing capacity-building programs. The study concludes that barangay procurement systems in the selected localities are generally functional and legally compliant, but their sustainability depends on institutionalized training, standardized documentation, digital record management, and stronger municipal-level technical support.
