We always seem to be creating something else we need. Don't get me wrong WHMCS is a great system, just like all things it has its limitations.
- Needed to create modules so users could see BW graphs and info
- Needed to create modules for users to set Reverse DNS
- We cannot integrate our Remote Reboots and Console applications into it
- In general it is not targeted towards Dedicated Servers and we find it a little clunky when using it in that way
