This article explains how to set up the Shopify app "Notify! Back in Stock|PreOrder" and points to be aware of. Setting up this app lets you easily add restock notification and pre-order features for out-of-stock products. However, there are also a few points to be aware of when using it, so we recommend understanding these before considering adopting the app.
What is Notify! Back in Stock|PreOrder?

Notify! Back in Stock|PreOrder is a Shopify app that lets you add two features: restock notifications and pre-order sales. It's available starting from a free plan, and can automatically accept restock notification sign-ups or switch to pre-order sales when a product goes out of stock. The admin screen supports Japanese, but some of the default Japanese text has minor issues, so you'll need to edit the text data for the Japanese version.

Points to be aware of with Notify! Back in Stock|PreOrder
The default Japanese text has issues

There are several places where the default Japanese text has issues, such as the wording of the restock notification button (default: "Notify me"). Beyond the setup described above, it's a good idea to also revise the wording on the restock notification and pre-order custom pages.
You can't configure pre-order conditions
Pre-order sales with Notify! Back in Stock|PreOrder can only be used when a product is out of stock. If you want to run a time-limited pre-order sale, you need to first set the inventory count to 0 to enter pre-order status, and then restore the inventory count after the pre-order period ends. Similarly, for pre-orders ahead of a new product launch, you need to set the inventory count to 0 to accept pre-orders, then change the inventory count on the launch date. This kind of operation takes effort and is prone to mistakes, and the inability to configure pre-order conditions can make operations more cumbersome.
No bundling control
Since pre-order products and regular products ship at different times, there are cases where you don't want them purchased together. Notify! Back in Stock|PreOrder has no bundling control feature, so you cannot prevent a pre-order product and a regular product from being ordered together.
No translation support
The text data in Notify! Back in Stock|PreOrder supports only one language and cannot be translated. So if you're running a cross-border store on Shopify, this is something to be aware of.
Conclusion
Notify! Back in Stock|PreOrder is a Shopify app that provides restock notifications and pre-order features for out-of-stock products. The setup process is relatively simple, but there are points to be aware of, such as unnatural default Japanese text and the inability to configure pre-order conditions. In particular, running pre-order sales can require extra effort, so it's important to consider this carefully before adopting the app. If you're running a cross-border e-commerce store, you should also keep in mind that it lacks a translation feature.
With the above points in mind, consider whether Notify! Back in Stock|PreOrder fits your store's operations and needs. Used appropriately, it can help streamline inventory management and improve customer satisfaction.
