I'm pretty sure CCBill states how much you would get paid on your sale. For example, if you charged $34.95 you'd probably get around $25, but I'm sure it says right on the site.
However, the bigger problem is that you only get paid on sales that the telephone company pays back to CCBill. So if the customer doesn't pay their bill, or if the phone company doesn't pay CCBill or something, you don't get paid! And since it's such a big delay in payment anyway, that means your customer would get full access to your site the entire time (unlike online checks where they get cut off when their check bounces).
So I'm hoping someone can tell me I'm wrong about this, or that the percentage of non-payments is low, but I doubt it
