<![CDATA[The development of information technology has encouraged various service businesses to adopt digital systems to improve operational efficiency, including in human resource management. Casysalon, as a business engaged in the beauty services sector, still faces obstacles in the employee attendance and payroll processes that are carried out manually, thus potentially causing recording errors, delays in salary calculations, and difficulties in monitoring employee attendance. This study aims to develop an online attendance application based on the Global Positioning System (GPS) and employee payroll at Casysalon using the Extreme Programming (XP) method. The XP method was chosen because it is able to support software development that is fast, flexible, and oriented to user needs through the stages of planning, design, coding, and testing. The developed application allows employees to record attendance online based on locations validated by GPS, while the admin can manage employee data, monitor attendance, and perform payroll calculations automatically. System testing was conducted using the Black Box Testing method to ensure all functions run according to user needs. The results of the study indicate that the developed application is able to improve the accuracy of attendance recording, speed up the payroll process, reduce data processing errors, and facilitate management in supervising and managing employee data. Thus, the application of the Extreme Programming method succeeded in producing an effective and efficient application in supporting the employee attendance and payroll process at Casysalon. ]]>
