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..?
Are you wanting to do like amelen said? Those can be found on netfirms and iPage etc. However you can check here whmcs.com/appstore/ they probably do have something like that, if not you can go somewhere like hingeweb.com and ask for a quote on what you'd like done! Good luck!
I'm confident that you could acheieve the attached design but may have to make some compromises (such as the highlight style of the SSL certificate).
You'd need to edit the addons section of the shopping cart template.
