Scored on 1,275 merchant reviews we hold for REZ Preorder, Back In Stock, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 1,275 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

This app helps build Notify Me button as required and is customizable as per our needs. This app also has Pre-Order button facility but i have used it yet. Would recommend to other sellers too.

Graet App! I gotta be honest, this App is very easy to use, very well develop and fast. It helps many of our customers to know when our products are back in stock and the notifications are easy to edit. Support is very quick and helpful. Thank you!

I like how easy to navigate and set up the app is, support is also easy to access with quick replies. I love having this iPad in my store, it has made pre selling and managing out of stock items much easier.

Absolutely amazing experience with REZ Preorder! Emma was incredible and provided outstanding customer service from start to finish. She was helpful, professional, and made everything incredibly easy. On top of that, the app works flawlessly — smooth, easy to use, and does exactly what it’s supposed to do. You can tell a lot of thought went into creating a great customer experience. Highly recommend to anyone looking for reliability and top-notch service!

Pretty easy to use and set up, I think there are just some features that I would like added like more customization of the preorder button look

I just migrated from another preorder app provider. REZ Preorder is a solid app that helps every merchant whose products are constantly out of stock due to high demand. Their customer service is top-notch and truly understands shop owners' needs. I encourage you to speak with one of their customer service reps to get a feel for what their service can offer. I can't wait for them to release the other apps they have planned for the future.

Well no limits is what we look for compared to other apps who have limits of 10 notifications. 10? that's half day out of full month Basic Structure totally worth adding for Extra Customer Experience

The app was really simple and easy to set up. Emma helped a lot with getting the customization just right to make it match my website better! For a free app I'm very pleased. I hope there is even more customization options in the future, especially for the email builder!
