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.

Synctrack® Estimated Delivery Date by Omega helps you display timeline graphics and estimated delivery date information (EDD/ETA) such as dispatch date, shipping date, delivery time & order delivery date. The shipping estimator allows you to set delivery date, and show animated estimated shipping dates on products, cart, checkout, thank you, order status page, and order email. Stores with clear expected delivery dates received fewer customer support requests and increased sales conversion rates.
