About

Odoo is an open-source suite of business applications founded in Belgium in 2005, originally as TinyERP and later OpenERP. It offers dozens of integrated apps covering CRM, sales, accounting, inventory, manufacturing, HR, marketing, e-commerce and websites.

Small and mid-sized businesses use Odoo as an ERP to run most of their operations in one system, often with help from certified partners. Recent versions add AI features such as AI agents for natural-language queries and task suggestions, AI document scanning for invoices and expenses, and AI-assisted content and lead tools.

As of October 2026, Odoo offers One App Free for a single app with unlimited users, a Standard plan with all apps at roughly $24.90 to $31.10 per user a month in the US on annual billing, and a Custom plan with Studio, multi-company and API access at a higher price. Odoo uses country-based pricing, and some AI features are billed by usage.
