iDempiere

iDempiere is an open source ERP, CRM, and supply chain management suite for running core business operations. Developed by a worldwide community of small businesses, implementors, and end users, it descends from ADempiere and Compiere and carries business logic refined over years of real-world use.

It is written in Java with a ZK-based web interface and runs on PostgreSQL or Oracle. A modular plugin system powered by OSGi lets functionality be extended and customized without changing the core, supporting accounting, manufacturing, and point-of-sale alongside ERP, CRM, and SCM.

The suite can be installed locally following the official installation guide, or explored without setup through hosted test sites. Documentation lives on a wiki and a Docusaurus site, with issues tracked in JIRA and builds handled by Jenkins.
