Business Profiles is an eBay feature. You can create profiles for your Payment, Shipping and Return Policy. Then you apply these profiles to your templates and listings. The huge advantage comes when you need to make a change, so, instead of making changes to a large number of listings, you simply edit the profile and eBay will automatically apply the change to all the listings that use that profile. Wonder Lister exclusively uses profiles. We highly recommend that you OPT-IN to use profiles so that if you ever need to use eBay's website, you can use the profiles on eBay's site as well. Unless you OPT-IN you will not get the option to use profiles on eBay site. Here is addition info on how to OPT-IN.
