ERP5
ERP5 · Lille, France · founded 2001
What it is
ERP5 is an open-source ERP package for organizations managing finance, inventory, orders, manufacturing, and other business operations. Its broader scope includes CRM, production management, supply chain, product design, accounting, human resources, and e-commerce. ERP5 supports multiple entities and is designed around a Unified Business Model. It has been implemented in areas including banking, government, trade, manufacturing, and aerospace. The software can be used and configured through a web browser, and its maker says all browsers are supported. It is deployed on-premise; a preconfigured virtual machine is available for end users who want an instance on their own server. The maker does not recommend that VM package for large production environments with many users or for development, and recommends SlapOS for production use and complex integrations. ERP5 is mostly written in Python and uses the NEO transactional NoSQL database and a relational SQL database, with MariaDB preferred. The software has a free plan and is free to download and use under GPL v2. ERP5 was founded in 2001 and is headquartered in Lille, France.
