Is this possible with cc processers?

I'm currently looking for a CC processor (RevEcom, 2checkout or worldpay) and although most things are clear to me I still have one question.

Is it possible to charge your customers for any extras that not occur every month (like extra bandwith,...) ?
For example when a customer uses too much bandwith in a certain month.

not with 2checkout, worldpay or revecom.

All are third party processors. You need a full merchants account like authorize.net, linkpoint as you will probably store their basic cc information.

Of course it is encrypted. =)
