An overview of Odoo, the open-source ERP

What Odoo is
Odoo is an open-source suite of integrated business applications (ERP) developed by the Belgian company Odoo S.A. On a single platform built with Python and PostgreSQL and used through a web browser, it covers sales, accounting, inventory, manufacturing, HR, CRM, and e-commerce, among others. It can run in the cloud or be self-hosted, and Odoo reports more than 16 million users worldwide.
Product philosophy
Odoo favors modularity over heavy configuration: capability is added by installing focused modules rather than parameterizing one monolith. It also prioritizes rapid evolution and interoperability over long-term stability, shipping a major release every year. That makes Odoo fast-moving and flexible — but it also means version upgrades are a routine part of ownership rather than a rare event.
What Odoo covers
Odoo spans most core business functions as integrated apps that share a single database: Sales and CRM, Accounting and Invoicing, Inventory and Manufacturing, Purchase, Project, HR, Marketing, Website and e-Commerce, and Point of Sale, among others. Because the apps interoperate on one platform, data flows between them without separate integration work.
