Hi Guys
Just a quick one is there a WHMCS module for this platform?

You should have searched the forum. Manager only has an API, but no addons or extensions.

There have been more look for example at Search results for 'integration' - Manager Forum or use plugin etc as keywords. In any case it is clear that this is not a direction Manager takes. Being multi-platform it would add lots of unnecessary complexity. You can use APIs though.
