Conflux Lite is an open-source groupware package distributed under the GNU GPL licence. Although the Lite version offers less functionality then Professional, it still includes all the core functionality, which should meet the needs of small companies. In case the client's needs increase and exceed those offered by Lite, the Conflux Lite server can easily and quickly be reconfigured into the Professional version, which offers extended functionality. The data already entered in the system will be all transferred to the new version.
