I need an all-in-one school ERP that runs entirely as an Android application. The app must cover day-to-day operations as well as reporting, so the build has to be robust, intuitive, and ready for direct Play Store deployment. Core scope • Fees collection: integrate a secure payment gateway, auto-calculate late fees, issue digital receipts, and feed data straight into the finance module. • Student data record: admission details, personal info, grades, and document uploads, all searchable and exportable. • Teacher data record: profiles, schedules, and basic payroll fields. • Parent communication: in-app messaging and push notifications tied to each child’s profile. • Attendance tracking: daily registers that sync to both student and teacher records. • Online assignments: create, submit, grade, and archive tasks from the mobile interface. • Financial reports: daily, monthly, and yearly summaries pulled from the fees module, exportable to PDF/Excel. Technical expectations – Native Android (Kotlin/Java) or a proven cross-platform stack such as Flutter; local data should sync to a scalable backend (Firebase, AWS, or a custom REST API). – Clean, well-commented code with full hand-over rights. – UI must follow modern Material guidelines; wireframes can be supplied on request. Acceptance criteria 1. Functional APK that passes Play Store review. 2. Demonstrable accuracy of fee calculations and financial reporting. 3. Real-time notification delivery tested on at least two Android OS versions. 4. Source code, build instructions, and brief technical documentation delivered at final hand-off. Proposed timeline: prototype within two weeks, testing week three, final release by week four—please outline any alternative schedule you prefer along with your tech stack of choice and past work examples that prove you can hit these milestones.
