A mobile application is required for a window cleaning business to digitalize their service bookings and payments. The app should allow customers to easily schedule cleaner visits to perform standard window cleaning tasks at regular intervals. Users must be able to browse available time slots on a calendar and select dates for window washing. It is imperative the app integrates with popular payment gateways to facilitate online transactions for completed orders. Users' booking histories and preferences should be retained to enable effortless recurring reservations. Notifications and reminders are essential to confirm appointments and prevent missed visits. The app backend needs to synchronize successfully with the window cleaning company's operations and workflow. Data regarding customers, bookings, payments and jobs must be securely stored and accessible to staff. Analytics and reports on bookings, revenues and customer retention will empower strategic decision making. The mobile application aims to streamline the window cleaning process, enhancing customer convenience and boosting the business. Suitable developer bidding on this project should demonstrate proven experience creating similar service based apps. Thanks in advance
