## Overview

Advance Billing System is a Django billing application. The principal workflow is a user request routed into the organisation app, where billing and customer operations are handled and application data is persisted; the README also documents GST, discounts, QR codes, and PDF invoices. The tree identifies these app boundaries, but the sampled source does not include the views, models, or URL definitions, so feature-level wiring is uncertain. Settings explicitly configure SQLite, despite the README listing MySQL.

Main entry points: [`Biling/urls.py`](https://github.com/mansii-09/python-billing-project/blob/main/Biling/urls.py) (Django routing), [`organisation/views.py`](https://github.com/mansii-09/python-billing-project/blob/main/organisation/views.py) (Organisation workflows), [`organisation/models.py`](https://github.com/mansii-09/python-billing-project/blob/main/organisation/models.py) (Organisation models), [`adminpanel/urls.py`](https://github.com/mansii-09/python-billing-project/blob/main/adminpanel/urls.py) (Admin panel routes)
