Pro Sites vs or and WHMCS MU PROVISIONING?

As I a reading over the WHMCS MU PROVISIONING plugin I run across the mention of Pro Sites and now confused if this is in addition or separate of the WHMCS MU PROVISIONING plugin

    Hello Shawn,

    Pro Site is separate plugin. It allows you to monetize your network. It has integration with WHMCS MU PROVISIONING plugin - so they can work both on same network - but that is not necessary to have both.

    With WHMCS you cannot for example give your users access to different sets of plugins depending on the level that was purchsed. But Pro Sites allows you to do that - and has also many other modules for limitations depending on levels.
    So if you use or not Pro Sites - that depends on your needs.

    Hope this helps.

    kind regards,
