As referenced on our VPS Managed Hosting page, we offer "WHMCS" as a billing panel for only an additional $5.00/month! If you'd like to purchase the license add-on, please contact our Sales Deparment via email (firstname.lastname@example.org) or open a Sales Department Ticket via our Help Desk.
WHMCS can be downloaded from within https://my.knownhost.com under the "Downloads" link.
To access the download area please ensure that you first login to your billing account at the following URL: https://my.knownhost.com/client/login/
Once logged in you will have a "Downloads" link on your top menu bar. This will allow you to access the available WHMCS versions.
WHMCS is a fully featured billing panel/system that integrates with cPanel/WHM. For more details check out WHMCS Features page.
