Pre-Order & Back-in-Stock makes it easy to manage pre-sales and notify customers when products are available. Set up pre-orders based on inventory levels or schedule them with start and end dates. Automatically tag orders with labels like “preorder” or “shipping date” and send confirmation emails to customers. For back-in-stock functionality, customers can subscribe to get notified the moment a sold-out product is restocked, helping you recover lost sales and improve customer satisfaction.
