Back in the day when I was looking at merchant accounts, every one of them that I saw specified in their ToS that you were not allowed to charge until the day you shipped the product. (So you could charge at 10:00 in the morning, as long as the product went out with the 5:00 P.M. FedEx.) Although some allowed a 24-hour window to ship after charging.
Things may have changed since then.
