I agree that the system should prompt the GSA to take payment, but I think we should also be able to decline taking that payment. We get the majority of our business from military personnel and military contractors. They get paid on specific dates and may not have the funds in their cc account to cover the entire stay. So we work with most of them to take partial payments or weekly payments as they need. So, we leave their payment method as cash until they can make a cc payment. Then we change the mothod to cc, take an authorization on the card and charge it accordingly. Once payment is obtained, we change the payment method back to cash.
