iDempiere

iDempiere is a free, open-source enterprise resource planning (ERP) and customer relationship management (CRM) platform designed for small to midsize businesses. It originated as a community fork of Adempiere, which in turn descended from Compiere, and began around 2011 as developers and users collaborated to extend and improve the project. The program is maintained by a global community of volunteers and organizations.

Technically, iDempiere is a Java-based application that runs on standard Java application servers and uses relational databases such as PostgreSQL (with Oracle as an additional supported option). It follows a model-driven, plug-in architecture that facilitates customization and extension without altering core code. The software provides modules for financial management, procurement and sales, inventory and warehouse management, manufacturing, project management, and customer relationship management, with support for multi-organization, multi-currency, and localization requirements.

Deployment and governance: iDempiere can be deployed on-premises or in the cloud and is accessible through a user interface that combines web-based and traditional client elements. The project is community-driven, with contributions from individuals and companies around the world, and releases are coordinated through public repositories and community processes.
