Organizations are increasingly adopting open-source Human Resource Information Systems (HRIS) due to their cost-efficiency, configurability, and scalability. However, selecting the most suitable platform remains a major challenge due to diverse functional requirements. This study aims to determine the most appropriate Free and Open Source Software (FOSS) HRIS based on key decision-making criteria. A comparative evaluation was conducted on three platforms, IceHRM, OrangeHRM, and Sentrifugo, using the Analytic Hierarchy Process (AHP) to calculate criterion weights and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to rank the alternatives. Seven HR functional domains, including employee management, attendance, recruitment, and payroll, formed the evaluation framework. The results indicate that IceHRM achieved the highest relative closeness score (RC = 0.7892), followed by OrangeHRM (RC = 0.7428), and Sentrifugo (RC = 0.0133). Based on the evaluation model, IceHRM is identified as the most suitable option due to its alignment with prioritized functional criteria. The proposed AHP-TOPSIS approach provides an objective and replicable decision-support model for organizations undertaking HRIS selection as part of digital transformation initiatives.
