## Overview

This is a Flask/SQLite event-services marketplace with role-based admin, vendor, and user workflows. The principal user journey is browsing vendor products, maintaining a cart, submitting checkout details and a payment choice, then tracking the resulting order; users can also maintain guest lists. The application is concentrated in app.py, which owns route handling and database access. README capabilities are included where excerpts do not show their route implementation; wiring for those unsampled details is therefore not inferred.

Main entry points: [`app.py`](https://github.com/anish-000/event-management-system/blob/main/app.py) (Flask application), [`templates/auth`](https://github.com/anish-000/event-management-system/tree/main/templates/auth) (Login & signup), [`static/js/auth.js`](https://github.com/anish-000/event-management-system/blob/main/static/js/auth.js) (Auth interactions), [`templates/admin`](https://github.com/anish-000/event-management-system/tree/main/templates/admin) (Admin screens)
