I need a web-based coaching management system for our NGO built with PHP and MySQL that can run seamlessly across multiple branches. The platform must be responsive so students and staff can work comfortably from any phone, tablet, or desktop. User roles The application should separate permissions for Administrator, Coach/Instructor, Student, and a branch-level Center account so each location manages its own data while head office retains full oversight. Key modules • Student enrollment and profile management • Timetable and class scheduling with clash checks • Payment processing, fees ledger, and branch-wise finance reports • Attendance tracking for both students and instructors • Lead / inquiry capture and follow-up workflow • Exam result entry, marksheet generation, and certificate printing (print-ready PDF) • Consolidated reporting dashboard covering academics, finance, and branch performance Communication layer Automatic notifications have to work through SMS, WhatsApp, and Email: admission confirmations, class reminders, fee alerts, exam results, and bulk announcements to selected groups. Multi-branch logic Every Center should see only its own students, classes, and payments, while the Administrator can drill into any branch or pull combined reports. UI expectations Clean Bootstrap-style design or similar framework, fast loading pages, and mobile friendly layout are essential. Please use standard, well-documented PHP practices so future maintenance is straightforward. Deliverable A fully working, source-code-included system that I can place on my hosting, along with a brief setup guide and a database dump for initial testing.
