Dolibarr

Dolibarr is a web‑based ERP and CRM suite written in PHP with JavaScript enhancements, aimed at managing the full range of business activities such as contacts, suppliers, quotations, invoices, orders, stock, agenda, human resources, accounting, and more. It can be deployed on‑premise or in the cloud and supports any standard web server and database stack (Apache/Nginx with MariaDB, MySQL or PostgreSQL). The software is released under GPL‑3.0, allowing anyone to use, study, modify, and redistribute it without subscription fees.

The platform targets small, medium and large companies, foundations, freelancers, and associations that need an integrated solution for sales, procurement, inventory, finance, and productivity. Users can enable only the modules required for their workflow, and the built‑in integration between modules eliminates duplicate data entry. A marketplace of add‑ons and a low‑code Module Builder let administrators extend functionality without deep programming knowledge.

Dolibarr’s distinctive aspects include its fully open‑source model, a large community that contributes to continuous development, and a straightforward upgrade path that preserves data across versions. Installation options range from one‑click packages for various operating systems to Docker images and manual setup, catering to both low‑technical and experienced IT users.
