Give shoppers confidence with accurate expected delivery dates, shipping ETA and delivery promises across every buying journey. Automatically calculate processing time, dispatch date, transit time, holidays, lead days and cut-off times to display personalized order delivery date on product pages, collections, cart, checkout and email notifications. Reduce WISMO tickets and automate delivery estimates using advanced rules for inventory, shipping methods, vendors, tags, warehouses and ZIP codes.

Managing personalized orders often requires manual communication, proofs, and file preparation, slowing fulfillment and increasing operational effort. CustomEase streamlines the process by letting shoppers design directly on your product page while you receive production-ready files instantly in the admin. This improves accuracy, reduces back-and-forth, and makes it easier to scale custom product workflows efficiently.
