Pay with credit card after manual account set up

Hi,

I have manual added a site, and set it to be a "standard account" paid level until the 16 november. Today the 13, the client wanted to add his credit card so it was paid on that from the 16. of november... But it does not work? Any reason, bug or does he have to wait until the 16 of november, or how does he start to pay with credit card...
