There is the ability to advance buy a product before it's in stock or launched.
Go to Products > Products and then select the required product.
Out-of-stock actions – Select if customers should be able to buy the product in advance before it is not yet available for sale, or sign up to receive an email notification when the product is available. Note that the "Buy in advance" option requires that you have the product in stock, while the "Sign up for notification" option requires that you have it out-of-stock. Also, the "Sign up for notification" option cannot apply to products which are tracked with options.
These orders will then end up in the backorder process awaiting confirmation and shipping when the product is available.
Go to Orders > View Orders and select Backordered in the searches.
All orders with outstanding shipping through out of stock action will be within this status.
