Yes, you can use a third party SSL Certificate on a Pinnacle Cart hosted account. There is a fee for adding a Dedicated IP address to your account for a third-party certificate. There is essentially two parts to this setup. First, you will need to generate the CSR from Plesk (click on SSL Certificates under Additional Tools) and purchase the certificate (or give the CSR to the SSL provider). Then, once everything is verified and you have the certificate file, you will need to upload it within Plesk. You can do this from the same screen. Once you've completed this, contact our Support Team for further assistance: http://www.pinnaclecart.com/shopping-cart-software-support.htm
Keep in mind, you can always purchase a certificate directly from Pinnacle Cart and we'll install it for you. See the following for more information: http://www.pinnaclecart.com/pinnacle-cart-security-certificates.htm
