How do we bill courses for different students to one corporate credit card?

Our system is based entirely on email addresses for the sign ins. A specific email address = a specific sign in/profile/account. When ordering courses, you may use any credit card you wish, including a corporate card. Use the name/address and email address of the student and then in the payment section use the name/address as it appears on the card.
