A Java + JavaFX desktop application for managing inventory, sales, and staff roles in an electronics store. Features include bill generation, role-based access (cashier, manager, admin), and sales statistics.
Role-based Access: Three roles (Admin, Manager, Cashier), each with distinct permissions (e.g. only admin can manage users).
Product / Stock Management: Add, edit, remove, view product details, update stock, track inventory.
Billing / Sales: Create bills for customers, calculate totals, generate receipts.
Sales Statistics / Reports: View revenue, best-selling items, sales trends.
User Management: Admin can add or delete staff accounts and assign roles.
Security & Validation: Input validation to prevent invalid data; restrict access to functions based on role.
This project is built with a modular and object-oriented approach:
Model-View-Controller (MVC) / clear separation
