necrom did you test it with Enhance, since it has support for other control panels also?
Site Builder Automation
When ordering Web.com Site Builder as an addon to a hosting plan, WHMCS and MarketConnect fully automate the Web.com Site Builder account setup process. This includes, for applicable actions, automation for FTP accounts, publishing, and upgrades.
For website publishing automation, the following details apply:
cPanel
WHMCS will create a dedicated FTP account within cPanel for use by Web.com Site Builder and will provision the site builder account with these FTP credentials.
When a user publishes their Site Builder website, it will connect to and publish the website using these FTP credentials.
Plesk
The FTP credentials will default to the domain, username, and password from the parent Plesk product with a publishing path in the httpdocs directory.
DirectAdmin
The FTP credentials will default to the domain, username, and password from the parent DirectAdmin product with a publishing path in the public_html directory.
Other Control Panels
The FTP credentials will default to the domain, username, and password of the parent product to which the Site Builder service is attached. If different, the FTP details must be updated manually (see below).
Updating FTP Publishing Credentials
FTP publishing credentials reside in custom fields that you can view and update when managing the site builder within the Admin Area.
To update the FTP publishing credentials in the Admin Area, follow the steps below:
Modify the values in FTP Host, FTP Username, FTP Password and FTP Path.
Click Save Changes.
Click Update FTP Publishing Credentials to push the new details to Site Builder.
