What Odoo Does

Imagine that instead of a dozen separate services, a company uses a single system:

• CRM for customers
• Sales management
• Purchases
• Inventory accounting
• Accounting
• Manufacturing
• Employee management
• Project management
• Helpdesk
• E-commerce
• Website builder

In Odoo, all these modules run on top of a single database and are tightly integrated with each other. For example, placing an order can automatically create an invoice, reserve goods in the warehouse, and create a delivery task.

Main Modules

The most demanded modules are:

• CRM
• Sales
• Inventory
• Purchase
• Accounting
• Manufacturing (MRP)
• Project
• Helpdesk
• HR
• Website Builder
• eCommerce
• Marketing Automation

In total, the ecosystem includes dozens of official applications and tens of thousands of community extensions.

Why Odoo is So Popular

1. Modularity

You can start with just CRM and sales, and then gradually connect inventory, accounting, and manufacturing.

1. Open Source

There is a free Community Edition with open source code. If desired, you can completely deploy the system on your own servers.

1. Good Customization

From a developer's perspective, Odoo is a quite powerful Python + PostgreSQL framework. You can write your own business modules, integrations, and automations.

1. Unified Platform

Instead of a combination of Salesforce + Shopify + Jira + accounting software, a company gets a single system.
