Odoo

Odoo Community Edition is a full open-source ERP suite — accounting, inventory, manufacturing, HR, and website/e-commerce are all separate apps within one platform, with CRM as just one of those modules rather than a standalone product. Odoo also sells proprietary Enterprise modules and managed hosting; only the LGPL-3.0 Community Edition is covered here. It runs on the official Docker image with a PostgreSQL backend.
