With PreProduct, you can either add our native Shopify block via the customize editor, or alternatively add our snippet directly into your theme. Once you create a pre-order product listing in PreProduct, a pre-order button will replace the standard ‘add to cart’ button on your website, allowing customers to pay for pre-orders. Like some other apps, PreProduct supplies a default pre-order button out of the box. However, you can tell PreProduct to use your native Shopify store button too.
