Dolibarr

Dolibarr is an ERP and CRM suite for companies, foundations, and freelancers. It manages day-to-day business activity such as contacts, quotes, invoices, orders, stocks, agenda, accounting, and human resources from one web application.

It runs as a standalone install or over a LAN or the internet, written in PHP with JavaScript and backed by MariaDB, MySQL, or PostgreSQL. Around 100 modules ship by default, covering products and services, point of sale, projects and tasks, reporting, data import and export, REST and SOAP APIs, LDAP connectivity, and AI features via API, with more add-ons available.

Dolibarr is self-hosted, with packages for Windows, Debian and Ubuntu, Red Hat-family distributions, and Docker, plus a commercial cloud offering. It is licensed under GPL-3+.
