B2stock: Back In Stock notify , 84 reviews

Excellent app! and the support team is amazing. it would be awesome to have any integration with omnisend, klaviyo, and some other apps for email marketing

I have been using this app for a bit now and I love it! It's great to see what customers are wanting and helps when deciding what to re order.... this is a must have! support is quick to respond as well!

Easy and good customer service, we have been using it since 2017.
It does precisely what it promises...

This app is well done and exactly what I needed. A few things you couldn't customize were easily changed by asking their support to update for you.
Compared to other "back in stock notifiers" this one is the cleanest-looking, easiest to use. Plus it's a great deal. Anyone selling stuff in Shopify should be using this app.

So far so good!!

Great App & even better customer service. I was having some trouble on the install with getting the app to work seamlessly with our theme. They were super quick to get into our backend and fix the issue. Now, we are loving this app and its showing to be very useful for our customers.

Thanks guys!! Keep up the good work!

Great little app to notify potential clients when an item is 'out of stock' instead of oversell or pre-order items or make your customers check every day. The app doesn't always work with your theme, but when you request they install it, it's fixed within no time and working properly.

Excellent app. Even better customer service. Highly recommended!

Amazing App , easy to install and easy to use , the best for my www.seven-50.com website!

This app is amazing! and for $3 you can't go wrong! - customer support is fast and FREE! very impressed :)

Update 10/1/18: Works with transfers now! The bug has been resolved. Happy to recommend this app wholeheartedly now that this major oversight has been fixed.

UPDATE 7/27/18: I've been in contact with the developers via email, and they are saying the issue was caused by a change in Shopify's API - I know that Shopify did change the area of the API they are referring to, and after some discussion, it appears they are on track to release an update soon that will address this change.

I'm a little disappointed they did not proactively adjust their code for this change, and/or test to see if their code would break when the change went into effect, but testing does seem to be something that most of the more feature-rich, but less pricey, apps are lacking. This app DOES have a comprehensive, if not intuitive, UI - which could make it hard to test.

I've updated my review to 4 stars and asked them to let me know when the app is ready for re-testing. I will update again once that is done. If it fails the re-test, I will adjust stars - if it passes, I think 4 stars is appropriate for what is essentially a good app, at a great price, that at the moment lacks some oversight and testing.

I was very surprised, and disappointed, and a touch angry, to realize this app is not sending email notifications when a transfer accepts inventory. (THANK you other reviewer who pointed this out). We'd been ignorantly relying on this app for a while. I thought it was excellent. I have also emailed the developers to see what they say, but for that reason, unless this is fixed, this app will be an absolute failure for us for sure. I'm greatly aggravated to know this app has been failing to work in that way for a while, and wondering how many sales we've lost as a result.
