This study introduces ”Inventaire,” a perpetual inventory system designed to enhance the accuracy of inventory records for MSME e-commerce distribution channels. Through the integration of barcode scanning and an SQL-based desktop application, this system enables real-time monitoring for accurate and efficient inventory management, especially for non-perishable goods. The study employed a quantitative approach, surveying 200 respondents from an MSME e-commerce sector to evaluate critical factors impacting inventory accuracy. Significant factors identified include staff skill, stock audit systems technology, and inventory coding, which contribute positively to inventory record accuracy. Factor analysis and correlation methods were utilized to examine relationships among identified factors, revealing that effective inventory management, robust control strategies, and minimized record inaccuracy are essential to optimizing inventory accuracy. The results indicate that leveraging a perpetual inventory system with advanced barcode technology and structured inventory practices can significantly reduce errors in inventory records, ultimately improving operational efficiency in MSME e-commerce settings.
