Develop Offline School Administration System

I need a complete, offline Administration Management System for my school that can run smoothly on our local network with no reliance on an internet connection. The core requirement is a robust back-office suite that lets us store and manage all student and staff data while automating day-to-day administrative tasks.

The must-have modules are:
• Fees management: configurable fee heads, concessions, receipts, and outstanding reports.
• Examination management: exam scheduling, grading workflows, result analysis dashboards, and one-click admit-card generation.

The interface should be intuitive enough for non-technical staff yet secure with role-based logins. I’d also like printable and exportable reports in PDF/Excel and a clean installer that lets us deploy on Windows machines in a few clicks.

Deliverables
1. Executable/installer for the full offline system
2. Complete source code with build instructions
3. Step-by-step setup and user guide
4. Brief hand-over session to walk us through key workflows

If you have previously built desktop apps in .NET, Java, or Python (Tkinter/PyQt) tailored to schools, let me know; reusable frameworks or samples will speed things up. I’m aiming for a stable MVP we can grow over time, so clean, well-documented code is a priority.
