Best Shopify Back in Stock App [2022]

Out of stock inventory shouldn’t affect your sales!
There are specific Shopify apps designed to let your shoppers subscribe to back in stock alerts and bring them back when the product are in stock again.
Let’s dive into what back in stock alerts are and a comparison of the different apps you can set up to capture interested shoppers.
What are Back in Stock Alerts?
Back in Stock alerts allow your store visitors to sign up to be notified when a product is back in stock. These visitors can choose the communication channel through which they receive these alerts— email, Facebook messenger, SMS, or web push notifications.
Once the product is back in stock, the subscriber will receive a message letting them know about its availability, bringing them back to the store and helping you recover sales.
Why do you need to set up back in stock alerts on your Shopify store?
Back in 2011, it was found that stock-outs cause a projected $25 billion in losses for individual businesses every year. This number is likely to have inflated in the last 9 years. This loss isn’t just a financial loss. An eCommerce store with out-of-stock products will see long-term negative impacts— customer loss, low satisfaction rates, and negative word-of-mouth.
With back in stock alerts, you can lower your losses by setting up a back in stock subscription on your unavailable products. This way, you won’t miss out on capturing these shoppers as new customers.
