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.

Most Shopify stores ship gifts with packing slip gift messages, anonymous packages, gift cards going to the buyer not the recipient, and manual bulk gift orders. Giftnote automates all of it: branded gift notes timed to delivery via live carrier tracking, cards sent straight to the recipient, self-serve multi address corporate gifting, automated Shopify orders with tax and shipping. Every giftee syncs to Klaviyo, so recipients that fall into a black hole become contacts you can market to.
