I'm using jWHMCS since february 2010 now on my website. I ordered jWHMCS including installation, and within a day it was all installed and configured. It worked like a charm, and made my site perfectly integrated with WHMCS.
Yesterday I had a problem after a Joomla, jWHMCS and WHMCS upgrade. I mailed them, and within a couple of hours they fixed it for me. These guys rock!
