Create New Odoo Modules
Extend Odoo's functionality with Python. Build powerful features in hours, deploy to production in minutes.
How to Create an Odoo Module
Follow these steps to build and deploy your first custom module in production.
Choose Your App
Select an app to get started.
Set Up Your Environment
Install Python 3.8 or newer and PostgreSQL 12 or newer. Clone Odoo from GitHub. Create a custom-addons directory. First-time setup takes about an hour; subsequent projects take minutes.
Create Your Module Structure
Create a new directory in custom-addons. Write a manifest file that declares your module name, version, and dependencies. This is just YAML and boilerplate, no coding yet.
Build Your Features
Write Python code to define models, fields, views, and workflows. Inherit from Odoo base models. Test your code locally in development mode before pushing to staging.
Deploy to Production
Push your code to Odoo.sh or your production server. The system runs tests, handles migrations, and deploys without downtime. Your module is live in minutes.
What is a Custom Odoo Module?
An Odoo module is a Python package that extends the platform. It can add new fields to existing models, create entirely new applications, automate workflows, or integrate with external systems.
Every module has a manifest file (like package.json for Node.js). This file declares the module name, version, dependencies, and what it includes. Modules inherit from Odoo's base models, so you're building on proven architecture.
40,000+ community modules already exist. Many solve common problems: invoicing integrations, multi-warehouse logistics, CRM customizations. You can study them to learn patterns, or add them as dependencies.
Custom Modules vs. Odoo Studio
Odoo Studio is a low-code tool for quick customizations: add a field, create a view, set up automation rules. It's fast and requires no Python.
Custom modules give you full Python power. You can integrate APIs, build complex business logic, optimize database queries, and version-control your work in Git. Custom modules survive Odoo updates. Studio changes can break or be reverted during upgrades.
Use Studio for simple changes. Use custom modules for anything you need to maintain long-term.
Why Host with Opsily?
Stop managing infrastructure. Focus on creating Odoo modules.
No Setup Required
We handle Python, PostgreSQL, system dependencies, and maintenance. No SSH access, no package updates, no database tuning. Your team starts coding immediately. Development, staging, and production environments are pre-configured and ready.
Automated Deployment Pipeline
Push code to your repository. Our CI/CD system detects changes, runs tests, and deploys without downtime. Rollback to a previous version instantly if something breaks. Deploy frequency is limited by testing time, not infrastructure.

Common Questions
A custom Odoo module is a Python package that extends Odoo's functionality. It can add new fields to existing models, create entirely new apps, automate workflows, or integrate with external systems. Every module has a manifest file that declares its dependencies and metadata. You inherit from Odoo's core models, building on tested architecture. Custom modules give you full Python power and survive Odoo version upgrades, unlike Studio changes which can break.
