If you have products that are out of stock, you can sell them as pre-orders. This is done by creating an alternate product template, and editing your payment settings. You can also use this customization to continue selling products that are on back-order.
The steps for this tutorial differ depending on whether you are using a sectioned or a non-sectioned theme. A sectioned theme is a newer theme that lets you drag and drop to arrange the layout of your store's pages.
To figure out whether your theme supports sections, go to the theme's Edit code page. If there are files in the Sections directory, you are using a sectioned theme. Non-sectioned themes were released before October 2016, and do not have files in the Sections directory.
If you are using a sectioned theme, then click the Sectioned themes button and follow the instructions. If you are using an older, non-sectioned theme, then click the Non-sectioned themes button and follow the instructions.
