Technical Event Management ERP System

Technical Event ERP System

🔗 Live Application:
https://technical-event-erp-flask.onrender.com

A simple Flask-based event management ERP with user, vendor, and admin portals. Uses SQLite and SQLAlchemy for persistence. The frontend is styled with the CoreUI theme (Bootstrap-based) and provides a clean, responsive UI for all pages.

Overview

This project is a role-based Event Management ERP System developed using Flask.
It simulates an enterprise workflow involving Admin, Vendor, and User roles, covering the full lifecycle from master data management to order processing and status tracking.

The system follows ERP principles such as role isolation, controlled data maintenance, and transaction lifecycle management.

Features

Authentication & Authorization

• Role-based login system (Admin, Vendor, User)
• Secure session handling
• Restricted route access
• Unauthorized access protection

---

Admin Module (Master Data Management)

• Manage Memberships (Add / Delete / Expiry tracking)
• Maintain Users (Add / Edit / Delete / Change Membership)
• Maintain Vendors (Add / Edit / Delete)
• Category-based vendor management

---

Vendor Module

• Vendor dashboard
• Add and manage products
• View vendor-specific items only
• View assigned orders
• Update order status:
  • Received
  • Ready for Shipping
  • Out for Delivery

---

User Module

• Browse vendors by category
• View products
• Add items to cart
• Quantity management
• Checkout system
• Order tracking

---

Cart & Checkout

• Persistent cart storage
• Quantity controls
• Order creation
• Automatic cart clearing after checkout
• Payment method selection

---

Order Lifecycle

The system follows a clear, role-driven ERP workflow:

1. Admin creates vendors and users (master data management).
2. Vendor adds products, which become available to users.
3. User browses vendors by category, adds products to the cart, and checks out.
4. After checkout, an Order record is created for processing.
5. Vendor updates the order status step‑by‑step:
   • Received → Ready for Shipping → Out for Delivery.
6. User monitors and tracks the delivery progress from their dashboard.

This sequence ensures accountability, transparency, and a smooth order lifecycle.

Prerequisites

• Python 3.8+ (tested on Windows)
• pip for installing dependencies

Styling

All templates extend base.html which pulls in CoreUI (v4) from CDN. Custom page-specific CSS/JS can be injected with block placeholders.

Notes

• Sample categories are seeded at application start if not already present.
• Error messages and special responses use message.html which is also styled.

Extending

• Add more categories in app.py or manage via admin.
• Replace SQLite with another database by changing SQLALCHEMY_DATABASE_URI.
• Enhance forms with validation or file uploads as needed.

Live Deployment

The application is deployed on Render and accessible at:
