Top 6 Best Back in Stock Shopify apps in 2022 (Latest Rankings)

It is a disappointing moment for your customers to find the red sold-out sign on the product they wanted to purchase from your website. In this case, two things may happen: the first and most probable one is that you lose a potential customer. Because they will search for what you couldn’t give them on other online stores and the chances are high that they will buy the product from one of your competitors. This is exactly what we don’t want. Right? 

In the second possibility, you keep your customers for yourself with a simple yet smart move. You tell them that the item they want is not available. But soon it will be back on your website. So all they need to do is to click on a button and wait for you to let them know as soon as the product is back in stock.

Here is the point where a Back in stock Shopify app can come to your help and save your customers.

In this article, we are going to get familiar with some of the best back-in-stock apps you can use for your Shopify store this year.

Why do you need Back In Stock Notifications?

Any online store that sells products should have Back in Stock Alerts. You make most of your revenue from the products that are most in demand. When this occurs, you can be sure that your customers won’t go away, so using this methodology is an obvious benefit. 

You will be surprised at what else these notifications can do for your online business.

Recognizing customers’ needs

Besides doing your customers a favor, you are doing yourself a favor by allowing them to receive back-in-stock notifications. Here’s how. 

If you do this, you will know exactly how many people are interested in buying a certain product that is not currently in stock at your store. 

The next time one hundred potential customers ask for these jeans, you can be their hero and give them what they really want as soon as possible.

Developing trust

Shoppers find it disappointing when products are out of stock. If you choose to take advantage of this situation, you can show your customers that you care.

Offering an alternative shows that you don’t want to let them down, which builds trust. When things go wrong, your customers know they can count on you. That’s what keeps them loyal.

Making social proof

Let’s say you pass a physical store and see there’s a long line of people waiting outside. Though you may not understand why they are waiting, you may subconsciously think that there is something worth waiting for there.

And that is exactly how the stock alert button works on your online store. You tell your potential shoppers that this product was so popular that it was sold out, then you let them join the waiting list. Having a waiting list creates the illusion that so many people wanted the same thing. 

Analyzing product popularity

Apply the same strategy in a different way if you’re not sure which products will do well on your Shopify store. But how? 

See how many people sign up for the waiting list for the product you are about to launch by adding a “coming soon” button. By using this strategy, you create a new inventory that will be popular and in demand.
