The purpose of this research is to design an electronic service payment application system which is expected to make it easier to process data and transactions properly and quickly. The system is designed using the Research and Development Method because it is more precise. Where in building this system used System Design tools, namely Data Flow Diagrams (DAD), Context, Zero and Detailed and using the Java programming language with Netbeans and MYSQL Database using Xampp. The results of research that has been carried out at the MS Computer Store, with the existence of an electronic service payment application system replacing the old system, the current employee performance becomes more effective and efficient.
