If you want to install a fresh instance of WHMCS on your cPanel account you can do so very easily with Softaculous. Softaculous is an auto-installer for cPanel that can auto-install over 266 useful scripts. WHMCS, a management, billing, and support solution for online businesses, is an add-on product that costs $10 per month.

Note: if Softaculous isn't currently available in your cPanel account (Shared hosting customers get it by default) you can request to have it installed by our friendly and helpful support staff! It's a mere $3 a month, and one of the best features of Softaculous is that you can set it to auto-update your WordPress version! As each new version of WHMCS includes valuable security patches that keep your site safe and secure, we think Softaculous is a worthy buy.
