Back in Stock works great & integrates easily into Shopify.

It's a great resource to notify customers when items that our out of stock are restocked & looks clean on the website.

The Back in Stock team is quick to respond to customer inquiries and respond quickly to the Chat Feature. Thank you Leslie for helping update our theme to make it look cleaner online.

Back in Stock has been instrumental in helping us recover lost sales due to stockouts. Manny was especially helpful today in walking me through the new Shopify-native version.
