In case you haven’t seen the press release (Openbravo broadens support for Ubuntu with commercial open source ERP package), Openbravo now provides a fully-supported, subscription-based ERP offering on Ubuntu’s technology stack, with an easy-to-install native Ubuntu package. The pre-integrated and supported technology stack features Ubuntu 9.04, PostgreSQL 8.3, and Tomcat 6. If you want to skip the press release and head straight to the goodies, this link will tell you how.
So now what’s your excuse for not implementing Openbravo ERP? ☺
