The Complete List of Odoo Modules: Every Module Explained

Finding a unified platform that adapts to your unique operational needs is essential. The Odoo system is a comprehensive and modular ERP software suite designed to integrate all your business processes seamlessly.

Odoo thrives on flexibility and a collection of core modules, including CRM, Accounting, Inventory, Human Resources, and more. The modules provide the essential framework for managing any business. This foundation is exponentially expanded by the vibrant Odoo community and the extensive Odoo app store, which hosts thousands of specialized applications.

Odoo, although a user-friendly and flexible platform, is complex and has numerous modules, which can confuse first-time users and even complicate things for experienced ones. We have created this article to guide you through all the Odoo modules, their out-of-the-box capabilities, and customization options.

What Are Odoo Modules?

Odoo modules are the specialized, functional building blocks of the ERP system. Each. A module manages a specific area of your business, for example, the Odoo accounting app for finance or marketing modules for campaigns. These integrated modules work together to manage all your sales activities, inventory, projects, HR, and more from a single dashboard. Odoo allows businesses to streamline operations. It helps companies get rid of disparate systems, spreadsheets, legacy software, and scattered documents and collect everything in one single source of truth.

Are Odoo modules free?

Odoo operates on a dual-license model. The Community Edition is a free and open-source version of the enterprise resource planning platform, with a robust suite of core modules at no cost. For many businesses, this is an excellent starting point.

Odoo Enterprise Edition is a paid subscription that includes advanced features, official support, automated hosting, and a wider range of sophisticated apps. This makes Odoo modules both free and paid, with some companies deciding to start with the free Community version to establish core processes and later adapt Odoo with paid enterprise apps. Additionally, businesses consider Odoo implementation services as their business needs grow in complexity.

What’s the difference between Odoo apps and modules?

In everyday conversation, the terms “Odoo apps” and “Odoo modules” are often used interchangeably by users. However, there is a subtle technical distinction. A module is the fundamental unit of functionality within the Odoo framework—it’s the actual code package that adds features. An app typically refers to a module (or a collection of modules) as it is presented and sold in the Odoo App Store, often with a commercial or user-friendly focus.

When Does Odoo Need Customization?

While Odoo has an extensive library of core and third-party modules, sometimes customization is unavoidable. Tailoring involves matching the system to your business’s unique workflows and adding capabilities that off-the-shelf solutions cannot address.

You likely need customization when you must:

• Support a unique, non-standard business process that is core to your operations
• Meet specific regulatory or compliance reporting requirements in your industry
• Integrate with a proprietary or legacy system that Odoo doesn’t connect to by default
• Create highly complex, automated reports or dashboards beyond standard tools
• Build a specialized user interface for specific roles (e.g., a kiosk mode for warehouse staff)
• Develop a brand-new, monetizable feature or product on top of the Odoo platform
• Automate a multi-step workflow that involves data or actions outside of Odoo’s standard automation scope
• Fully white-label the system for resale or to match strict corporate branding guidelines for clients
