Payment Processing!!!

Would any one please comment on this?

Actually I want to know if the idea of having my services such as; hosting’s signup button linked to my shopping basked, so that my new customers can go through the shopping basket to order their new account.

The reason I am thinking about doing this way is that my shopping basket has my WorldPay account already incorporated, this way I don't have to go through setting up WorldPay again.

Also my shopping basket has a recurring facility, do I use this option for monthly recurring on hosting account or is better to do it through WorldPay?

Please any comment will be much appreciated.
