Hey guys. A customer of mine owns a network of about 5 sites and he plans on launching a few more. One of the ways he makes revenue would be ads on all the networks. He offers various plans such as ad location, ad on site per month, rotating ad space etc. Right now he does all this BY HAND!. I think thats crazy managing multiple sites and editing, changing ads by hand on a daily or monthly basis. So my question is.. Is there software I can get that can manage all the ads on all his websites? This is a custom website so sorry, no wordpress plugin suggestions please.
