This study investigates the effectiveness of Point-of-Sale (POS) systems in improving operational efficiency and customer satisfaction among selected fast-food establishments in Malanday, Valenzuela City. As technology becomes increasingly integrated into food service operations, POS systems serve as crucial tools for streamlining processes such as inventory management, error reduction, and order accuracy. The study aims to assess the relationship between these system features and levels of customer satisfaction, considering respondents’ demographic profiles. A descriptive-quantitative research design was employed, utilizing structured survey questionnaires to collect data from purposively selected participants, including staff, managers, and customers. Ethical protocols such as voluntary participation, confidentiality, and informed consent were strictly followed throughout the process. The validity and reliability of the research instruments were ensured through pilot testing and expert validation. Data analysis involved frequency and percentage distribution, weighted mean, and a t-test to determine significant differences in perceptions. The results revealed that POS systems are effective in enhancing both operational efficiency and customer satisfaction. Moreover, statistical analysis showed no significant difference between these two variables, suggesting that POS effectiveness supports both operational and consumer outcomes equally. These findings provide insights for fast-food businesses aiming to optimize digital tools for service improvement.
