• /api/vendors/{id}/ - GET, PUT, DELETE
• /api/purchase-orders/ - GET, POST

• vendors - Django app for related models
• purchase_orders - Django app for related models
• common - Django app for helper functions and boilerplate
• analytics - Django app for performance tracking models
• api - Django app for API views, serializers, urls and services

• SRP (Single Responsibility Principle) - Each class and function has a single responsibility
• DRY (Don't Repeat Yourself) - Repeated code is refactored into helper functions
• KISS (Keep It Simple, Stupid) - Code is simple and easy to understand
• YAGNI (You Aren't Gonna Need It) - Only necessary features are implemented
• Beautiful is better than ugly - Code is clean and readable (ZEN of Python)
• Readability counts - Code is easy to read and understand (ZEN of Python)

• Custom token-based authentication : Token is generated when a user is created and is used to authenticate the user for all API requests (But for this MVP, the Token is generated using a Custom Random String stored in .env file and is used for all users)
