When your customers click on the "Pre-Order" button, they will be redirected to a regular order page. You can sell the product even when it is out of stock to capture interested buyers at the right time.
Stop losing sales every time you run out of stock or drive shoppers to a page of coming-soon products. PIX - PreOrder app automatically replaces your “coming soon”, “sold out”, “out of stock” buttons with a “pre-order now” option.
