The open-source ERP that actually scales
Odoo runs everything from a single founder's CRM to enterprises with 10,000+ users — without the seven-figure license fees. Here's what makes it different, and how it compares to SAP, Oracle, Microsoft Dynamics, and the cloud-only suites.
What Odoo actually is
Odoo started in 2005 as TinyERP. Today it powers more than 12 million users across 120+ countries and ships 40+ official business apps — all sharing the same database, the same UI, and the same Python / PostgreSQL stack.
Pipeline, quotations, sales orders, subscriptions, rentals, point of sale, and a built-in customer portal.
Full double-entry accounting, multi-currency, multi-company, bank reconciliation, tax engine, and consolidated reporting.
Multi-warehouse, barcode, serial / lot tracking, BOMs, MRP, work orders, quality control, and PLM.
Recruitment, employees, payroll, time off, expenses, fleet, projects, timesheets, and helpdesk.
Drag-and-drop website builder, eCommerce, blog, forum, eLearning, and live chat — same login, same data.
Python 3, PostgreSQL, OWL frontend framework. Self-host or use Odoo Online / Odoo.sh. No proprietary lock-in.
