If you have your own merchant account and enable the credit card payment, the system will authorize and capture the credit card for you along with the order pipeline. If there is an issue with authorization or capture you need to coordinate with your customer and merchant provider to get credit card authorized or captured manually. Merchant provider usually gives you the access so called virtual terminal which allows you to authorize credit card manually. Ask your merchant provider for details. After you get credit card authorized or captured manually you could use the "Edit" button in the Order Status line to change the order status to the next step. System will pick it up and run the next step in the pipeline.
