Our business site is not on wordpress, it is html coded site, I coded it myself, as I am a web developer, but I am new to affiliate programs. I know there are sites like clickbank and others, where I need to add some code to our payment page on a specific product item, but the thing is we sell services, not products. Our client need to send us a request email and discuss all his order details via email with our support team and than he sends us his order details via email also, so how should I add a tracking code? To our general contact form or should I create some order form with a tracking code for each reseller ?
