Don’t worry, we've done all the legwork for you and compiled a list of the 9 best back-in-stock apps to instantly boost your Shopify store sales. Let’s dive deep into the list!

Benefits of Using Back In Stock Alerts on your Shopify Store

Back-in-stock alerts enable buyers to get notified about the restocked products via SMS, Email, Web notifications, and Facebook Messenger. These alerts help eCommerce stores to bring back the lost customers by notifying them about their favorite products once they are back. Let’s look at some benefits back-in-stock alerts bring with them.

1. Higher Customer Satisfaction

When buyers choose to come to your online store and find their desired product to be unavailable without any option of getting notified about the restocking of the product, they are less likely to visit your store again. Here’s when back-in-stock notification apps come in handy. These apps enable you to give your customers the option of getting notified about their favorite items once they are back. This way you can offer them an enhanced shopping experience and turn them into your permanent customers.

2. Grow your email list

With these alerts, you get the opportunity of growing your email list and later use them to pitch your new offerings. You can also use our Shopify Upsell and Cross sell app to increase your sales and average order value by upselling your products to these users.

3. Increase your user base

By giving your customers the option of buying the products which were unavailable earlier, you can boost your overall sales. When your current customers feel satisfied with your services, there is a higher possibility that they will suggest your store to their known ones. Thus driving more new customers and new opportunities of driving more sales.
