You will see how the users visiting the site will see the pre-order options.
Once you have set up your pre-order options on the product, you’ll see the Pre-order button replacing the “Add to Cart” button.

You will be able to pay immediately for the product using any of the gateways in your store. Yet, if you want your customers to pay later, you can consider the “Pay later” option available in the premium version as you can see in this page.
My account page
Once a product in pre-order mode is purchased, a pre-order section will show on customers’ My Account page.
This section will show the product, order number, the price paid, and release date.
By clicking on the order number, the details will include the pre-order info.
