Dolibarr ERP/CRM is a software built by modules addition (you enable only features you need), to manage small or medium companies, freelancers or foundations. We can say Dolibarr is an ERP or CRM (or both depending on activated modules). It's an OpenSource project base on a WAMP, MAMP or LAMP server (Apache, Mysql, PHP for all Operating Systems). Dolibarr differs from other ERP or CRM softwares (like OpenAguila, OpenBravo, OpenERP, Neogia, Compiere, etc) because everything was made to be more simple: * Simple to install * Simple to use * Simple to develop
