About Back In Stock: Customer Alerts

Stop losing sales when inventory runs out.

Featured on a blog? Cracked that AdWords campaign? Your store can see a surge of visitors in moments. Awesome! But what if your inventory sells out?

Don’t lose sales when your inventory runs out. Back in Stock makes it easy for customers to sign up for a Back in Stock alert (Email or SMS Text Message). When you restock products the waiting customers are alerted instantly to bring them back to your store and complete the purchase.

Back in Stock is simple to setup and runs automatically.

Email messages that convert

Back in Stock works on the product variant level: customers are notified when the specific size or color they want is restocked. This gives you impressive rates of engagement and conversion.

Back in Stock brings customers back to your store and helps you convert those sales you otherwise miss with in stock notifications.

Simple setup. Powerful customization.

Installation is simple and takes less than 30 seconds. Simply hit Get App and a button saying ‘email me when available’ will immediately appear on all relevant product pages. We support a wide variety of themes out of the box. Optionally add SMS Text Message capability to your store and your customers can choose to be notified via email or SMS, which ever they prefer.

This button automatically connects to a Back in Stock pop-up form that has a field for email address and a drop-down menu for product variants.

Wish I found this sooner! I rarely do reviews but this was such a time saver and only wish i had this app sooner!! I have been thinking about setting up an out of stock button for a while but didn't have the time or energy to do some research. I was apprehensive about potentially coding something and for it taking hours. I also did not want to spend a lot of money on it as I am just starting out. Found this app and it was set up on my website within minutes! no coding required and I love how I can customize the text and colors to my brand. And its FREE . will most likely upgrade as I see fit. Thank you!!

I am taking time out of my busy day to write a positive review about my experience for this app. We installed it recently to add some automation to managing our 'back in stock' notification setup. Previously, we were using the built-in feature that came with our "Turbo" theme from Out of the Sandbox. It accepts the email requests and sends them to us, but isn't equipped to do anything about actually sending emails to the customers once items are restocked. So, we were manually having to send those emails. Terrible timesuck and I don't know why we put up with that for as long as we did. It's worth noting that after we installed this app, it appeared that our theme was overriding the code for the app. I emailed their customer support team and their developers immediately took care of it and setup an integration unique to our theme. No setup involved on our end for the fix. We tested it and it works flawlessly. Very happy. Also like how the reporting shows that we already made a few sales today from the back in stock app auto-notifying people. Thank you!

This is the very first Shopify App we have used that works exactly as it said it would right out of the box, and we have tried several. No developer time needed. We added it, configured it and had it working in minutes, and we are not very tech savvy people.

The app has made us thousands of dollars so far, and helped give us a ton of insight into what customers are looking for on our store.

Highly recommended!
