Traditional or semi-automated payroll processes at organizations like Tazu Hotel and Suites are plagued by systemic inefficiencies, extensive paperwork, human errors, and compromised data security. These legacy methods lead to operational delays and difficulty in record retrieval, collectively hindering effective payroll management. This research addressed these shortcomings by designing, implementing, and rigorously evaluating a secure, automated, Online Payslip Generating System (OPGS) using the Design Science Research (DSR) methodology. The OPGS artifact was developed with a secure technology stack (PHP/MySQL) and integrated the Bcrypt algorithm to protect sensitive financial data. The system features an automated calculation engine and an Employee Self-Service (ESS) portal for 24/7 access to payslip history. Empirical evaluation demonstrated substantial benefits: the OPGS achieved an 85% reduction in the time required for the monthly payroll cycle and a 99.98% calculation accuracy rate, effectively eliminating manual errors. Furthermore, the system achieved an "Excellent" rating with a System Usability Scale (SUS) score of 85.5. The findings affirm the OPGS as a technically sound, highly usable, and effective solution that transforms payroll into a streamlined and transparent organizational asset.
