Our project is very useful for car wash stations. Affiliate job managers register from our project and add their workers to the application as workers. Case managers will also need to enter the services provided for the machines into our application. And before each worker service the machines, they specify the machine number and the type of service to be provided in the application. At the end of the day, on the phone of the case manager, it is clear which worker should pay for which service and how much. In short, our application serves as an online report book for the work managers of car washes.
