Well. If you bring a customer with your CCBill code and the surfer is brought by another webmaster thru NATS code and this surfer signs up. Most probably what will happen is that in CCBill you'll see a sale and the webmaster in NATS will see a sale. Which is why many of the sponsors tell their affiliates to stop using CCBill codes and use the new sponsor codes. Additionally... when people get NATS (or other cascading aff system like MPA3), they usually (or most probably will some time soon) get accounts with other billing systems like Epoch/Paycom, Netbilling, etc. Not to mention pay by check, pay by phone ($30 charge in the phone bill), dialers, etc.
I personally would go with more billing options. Although this doesn't guarantee you shit
