Customers can choose to make a one-time payment with their account should they choose.

Make A Payment (One-Time Payment)

This is a handy section that lets customers pay a one-time payment should they need to.  The customer can enter their account number and payment amount, then proceed to step two.

Completing their One-Time Payment

Once the user enters their account and payment totals, they are asked to fill in their account billing information.  IF the user has added a payment method and saved, they can choose to use that during this checkout without even entering their credit card information.
