Open-source Dynamics 365 alternative: Odoo and ERPNext
Updated 7/19/2026
Dynamics 365 is billed per user and per module, and the cost climbs fast for a full company. Odoo and ERPNext offer an integrated ERP on your own server, with no recurring per-module licenses.
Odoo
Odoo is a modular suite: CRM, sales, invoicing, inventory, projects, HR, point of sale and a website builder, all integrated. You enable only the modules you need.
ERPNext
ERPNext is a full open-source ERP, strong on manufacturing, inventory and accounting. It is chosen by companies that want a robust system with no license cost.
Who it is for
- Odoo: businesses that want a friendly, modular, easily customizable suite.
- ERPNext: companies with complex manufacturing and inventory processes.
How to install them
Pick Odoo or ERPNext from the one-click app catalog. An ERP benefits from a plan with more RAM; start medium and grow as you add users and data.
