The existence of the motorcycle repair shop business continues to grow, along with the developments of motorcycle riders in Indonesia. However, the majority of riders do not know the existence of the repair shop, especially in the remote location or in the area where they have never visited before. This problem can make that business do not last long. The Motorcycle Repair Shop Information System Application is useful for answering problems related to motorcycle repair shops. "Call for Service" and "Promotion" are two main features of the application which implement E-CRM. The "Call for Service" feature is used to make emergency calls to the nearest repair shop if there is an unexpected situation on the road. The "Promotion" feature is used as a medium to attract as many customers as possible and to increase customer loyalty by providing attractive promotions to the application users. The implementation process uses computers with React Native software, SQLyog, XAMPP, Visual Studio Code and Android smartphones. The Black Box Test in the application reveals that the users can use the “Call for Service” and “Promotion” features from it. The results of data development analysis in the application shows that it only requires a storage space of 73,746 MegaBytes within a year, if there are 25 new data every day.
