This study evaluates the effectiveness, user acceptance, and impact of iProSES, a web-based inventory management system designed to facilitate automation and transition from manual, paper-based processes among MSMEs in the food sector within the Philippines' MIMAROPA region. Employing a mixed-methods approach, including quantitative surveys, system usage logs, and qualitative interviews, the research assesses system quality based on ISO/IEC 9126 standards and user acceptance through the Technology Acceptance Model (TAM). Results reveal a high overall user satisfaction score of 4.68, along with strong perceptions of usefulness (4.78) and ease of use (4.89). The system significantly enhanced inventory accuracy, operational efficiency, and error reduction, supporting sustainable adoption prospects. Regression analysis identified usability and functionality as critical predictors of acceptance, while qualitative feedback highlighted challenges such as internet connectivity issues and ongoing maintenance costs. Overall, iProSES demonstrates promising potential as an economical, user-friendly tool that can improve productivity in resource-constrained MSMEs, provided that barriers related to digital preparedness and infrastructure are addressed.
