The easiest way to increase sales from your existing traffic

You’ve invested valuable time and money getting customers to your website. Don’t lose out on a sale because the item they want to buy has just sold out. Back in Stock makes it easy for customers to quickly sign up for a back in stock email alert.

The moment an item is available, your customer is automatically sent an email with a buy now button. You’ve made an extra sale, plus your customer is left with a good impression of your store, rather than a bad taste in their mouth because they couldn’t buy what they wanted.

Measure demand, not just sales

It’s something every store owner needs to know: what items do my customers most want to buy? We can help.

Use the Back in Stock dashboard to immediately see what items customers want to buy. Or receive daily or weekly reports about which items are most in demand and the quantity you need to order.

Increase your profits by knowing rather than guessing what customers want.

Simple setup

Installation 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.

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.

There’s no need to edit an email template or pay for tech support. Simple!

Effortlessly scalable

Back in Stock regularly sends out about half a million emails a month – we can handle volume.

You don’t need to do anything special if you’re a large store installing the app. Just feel confident that it will work at scale and that it will continue to work in the future.

Powerful customization

Although our default button and pop-up form convert well, we appreciate that you want them to integrate seamlessly with your store. We make this as easy as possible. You can:

  1. Use your own custom button image (any image in PNG, JPEG or GIF format can be used)

  2. Change the copy on the pop-up form (particularly important if your audience are not English speakers!)

  3. Change the design of your pop-up form using CSS

  4. Superpower the back in stock form provided by Mobillia, Responsive, Retina and Parallax themes with our one-click install process

  5. Get customers to opt in to your mailing list at the same time they enter their email address if you use MailChimp, Campaign Monitor, Klaviyo, or Constant Contact

  6. Create custom integrations if you are a developer using our Javascript API

Super fast email delivery

About 60 seconds after you update your catalogue, your customers will receive an automatic email alert telling them that the item they want is back in stock.

This means that if you are running a sale, or simply sell and restock quickly, then you should see a much higher conversion rate. Time is money!

Super friendly and experienced support

If you’ve got questions, before or after installation, just drop an email to support@backinstock.org. We’ll get back to you quickly by email, and we won’t use tech language unless you do.

I've been using this app for over a year, and after trying the other similar apps on Shopify, this one is clearly the best. It takes one very important task off your plate: Keeping track of who wants to know when what is back in stock. There really is no reason to try to manage this yourself. All the editable customer emails and reporting are icing on the cake.

I can point to thousands of dollars of sales that this app has generated, and many hours of time saved by not having to manage and notify all those backorder people myself. Worth every penny.


It's not the cheapest out of stock app but it's definitely the best. We tested many of them out and decided on this one, even though it cost the most. The adage you get what you pay for is really true when it comes to these apps. Our monthly ROI surpasses the price we pay for this app. We also required a few custom modifications and support was super quick and helpful!


Great app and fantastic support. Couldn't recommend it highly enough!


Have used it for nearly 3 years and it has definitely helped add to the bottom line. It's a great app and highly recommended.


Have been using this app for approx. 4 years now in our shop selling gifts for men. Works like a charm sending notifications when an item is back in stock. Has helped us recover sales that may have otherwise been lost due to out of stock.


I switched over from "Restocked Alerts" and it was for the better. I'm paying $5 more compared to the other app but with this app, I don't have to deal with the headaches that the other app caused. Matt from the support team has been great! I sent them an email requesting some assistance with setting up the app and within a few hours, I got a response. I definitely recommend this app!


I cannot overstate the usefulness of this app for our shop. We experienced a nightmare-inducing warehouse issue congesting the movement of our inventory that started clear back in December and has continued interrupting regular shipping for us over the last 9 months. The loss of revenue has been completely maddening, but this tool helped us salvage customer interest in our products through the worst of it. The analytics show literally thousands of requests for notifications, the customization allowed us to really be open with our customers, and thanks to this app we've recovered tens of thousands of dollars in what would definitely have otherwise been lost revenue. Seriously, after looking at the numbers I've got to say that installing this app was probably the single most important marketing decision I've made in the last 9 months. Thank you Back in Stock!!


The App works great, and Matt is very supportive to any query and prompt in resolving it!


The app is awesome! The customer support is superb. Matt, was quick and willing to help get it set up just the way we needed it. A+ all around.


Really useful app that allows us to let customers know when products they are interested in are back in stock - has led to more sales!
