reliable way of tracking and crediting all referrals to you. Would you prefer to be paid once for each sale, or would you prefer a residual commission arrangement, where you get paid at regular intervals so long as your customer keeps using the host's services? Would you prefer the host to bill your customers directly, or would you prefer to bill your customers yourself and thus obtain the higher profit margin that usually comes with this? These are just a couple of ways to decide how you would like to be paid.
