We're looking to integrate an up-selling feature into our checkout process on hostseo.org. The idea is to add optional packages and features (SEO, web design packages, etc..). Some of the bigger hosts have got this done to a science and I feel like we've been a little behind. We use WHMCS for the billing cart. Are there any plugins for WHMCS that would allow to add up-sell offers, etc..?
