There are three versions of Centric CRM:
1. Enterprise. This version is a commercial version, licensed and payed for by the seat on an annual basis. The basic price is $400 per seat per year, with discounts for quantity and for longer terms than one year. Centric CRM Enterprise comes with source code and is fully supported.
2. Group. This is a free, licensed, binary only version limited to five total users. It comes with a full installer for either Linux or Windows.
3. Community. This is a free, unsupported, source code only version that you can download, install, modify, and use. The license is the Centric Public License, which is similar to most other Open Source Licenses, but differs in that it does not permit redistribution of the Centric CRM code, in either source or binary form. You can (and should!) view the complete license on our web page.
Hope this helps!
