A credit card payment authorization can be declined for many reasons. An invalid card number or card name are examples.
It is important to understand that a credit card payment that has been processed for authorization, whether accepted or denied, has been recorded in your MYOB AccountEdge company file.
Note: In order to authorize a payment, the payment must be recorded
How you'll handle a declined credit card transaction depends upon whether your transactions are changeable or unchangeable. (Choosing changeable or unchangeable transactions)
(Note: You can't edit a credit card payment that has been declined and then try to reauthorize it. If you edit a declined payment and try to reauthorize it, two payments will be applied to the sale: the edited payment and the reauthorized payment.)
