At one of my prior jobs the customer service department would authorize credit cards and I would then charge them 1-3 days later when the item shipped and I generated the invoice. Once in awhile we would run into issues on larger or custom jobs that would take a bit longer to manufacture and the authorization would drop off before I had a chance to charge it. Another issue I would occasionally run into was the customer would add to the order and the price change would be outside of the allowable increase in the charge or C.S. would forget to add shipping. In any event it was really just a matter of having C.S. reauthorize the card, but since you cannot legally keep customer CC data on file it means a call to the customer to get the information again.
