Create Your First Odoo Module in Minutes
Odoo modules are the building blocks of the ERP. Learn to build custom functionality that integrates seamlessly with your business apps. No cloud vendor lock-in, no setup headaches.
What Is an Odoo Module?
In Odoo, everything is a module. Sales, CRM, Accounting, these are all modules built on the same framework. When you create a module, you're adding new functionality to Odoo: custom business logic, new apps, or extensions to existing apps.
Modules in Odoo are Python packages with a specific folder structure. They define models (data structures), views (user interfaces), and business rules, all in one self-contained directory.
Why Build Custom Modules?
Heavy customization through the UI has limits. Once you need logic that Studio cannot express, you write a module.
Common reasons to write a module:
- Integrate with third-party APIs (payment processors, ERPs, webhooks)
- Build industry-specific workflows (automatic approvals, complex calculations)
- Extend existing apps (add fields, change views, override methods)
- Package reusable functionality for your team or the community
Odoo's Python-based architecture means the learning curve is manageable. You just need to follow the structure.
Create Your Odoo Module
The process follows Odoo's proven pattern. Every module starts as a folder with the same structure.
Choose Your App
Select an app to get started.
Set Up Your Development Environment
Clone the official Odoo repository and the tutorials repo from GitHub. Configure your addons path to point to your module folder. This takes about 10 minutes on a fresh machine.
Create the Module Folder Structure
Every module is a folder with __init__.py, __manifest__.py (metadata like name and version), models, views, and static files. Odoo scans this structure at startup.
Define Your Data Model (ORM)
Write Python classes that inherit from models.Model. Define fields (Char, Integer, Many2one, etc.) and methods. This is the logic layer, it handles database operations without raw SQL.
Build the User Interface (Views)
Create XML view files (forms, trees, kanban boards, searches). Link them to your model. Users interact with Odoo through these views.
Test and Deploy
Run unit tests to catch errors early. Deploy to Odoo.sh or your managed hosting. Install the module in production via the Apps menu.

Frequently Asked Questions
Everything you need to know about creating Odoo modules and deploying to managed hosting.
In Odoo, the terms 'app' and 'module' are often used interchangeably, though technically a module is a Python package that extends Odoo's functionality. The Odoo App Store shows 150+ pre-built modules like Sales, CRM, and Accounting. When you create a custom module, you're building a new extension following the same architecture. Your custom module is packaged the same way, can depend on other modules, and integrates seamlessly into Odoo. The difference is: official modules are maintained by Odoo S.A.; custom modules are yours.
