Running out of stock doesn't have to mean losing sales. PreOrder Now helps you keep things moving by letting customers preorder items before they're back or sign up for back in stock alerts when a product is restocked so you know how much to restock and who to notify first. Capture demand early, plan product drops in advance, and offer partial payments. Track performance with Google Analytics, and keep your store running smoothly, your customers informed, and your revenue coming in.

Wishlist Plus enables your shoppers to save favorites and return to them later. Comes with powerful APIs to customize wishlists and integrates with leading email services to send price drop and restock alerts. Helps shoppers organize products into multiple wishlists and share them via emails, SMS, and socials. Supports anonymous wishlists. Comes with detailed reports on shopper behavior. Includes a new Customer Accounts extension for easy tracking of all wishlists and browsing activity.
