I want to setup an affiliate program promoting a service not a product, so people can sign up to my affiliate program and promote the service. The thing is, when someone refers a potential customer, I will need to speak to the customer before they purchase. I assume that the only way to do this is to firstly speak to the referred customer after they click contact, and if they decide to purchase, then email them the purchase page. Obviously, the purchase page will be on the same site that the affiliate referred the potential customer to. Is affiliate tracking done with cookies, so if I did use the method above, would it still be tracked as a sale for the referrer? Is there a better way to do it? Am I missing something?
