Top 5 Shopify Stock Alert Apps for 2025

In the constantly changing world of ecommerce, keeping track of product availability is a crucial factor determining customer satisfaction. In other words, inventory management has become essential in today’s time for brands with multiple stores and a multichannel approach.

Businesses lose approximately $1.75 trillion every year due to overstocking, out-of-stocks, and returns. 

This highlights the urgent need for effective stock management strategies to ensure that businesses maintain adequate inventory levels. By doing so, they can enhance their ability to meet customer demands efficiently and prevent costly losses.

A Basic Understanding of Stock Alerts

Sometimes referred to as inventory alerts, stock alerts notify you regarding any changes in your inventory.

In addition to low-stock alerts, businesses are now integrating various other alerts in their Shopify stores including:

• Shipment
• Low-demand stock
• Huge demand stock
• Inventory reorder point

The type of alert relevant for your business depends on the specific needs of your inventory management, sales patterns, and operational goals.

Consider this: Kylie Cosmetics, one of the leading beauty brands, saw a 30% increase in sales after implementing stock alerts to better manage inventory across their online store and retail channels. By using real-time notifications for low-stock items, they were able to ensure popular products were always available to meet demand, ultimately preventing lost sales and customer dissatisfaction. 

How To Leverage Shopify Stock Alerts In Your Online Store

Stock alerts in Shopify are essential tools that keep you informed about your inventory levels, help you avoid overselling, stockouts, or overstocking. By strategically implementing stock alerts, you can optimize inventory management, enhance customer satisfaction, and maximize your revenue. 

Here’s a detailed guide on how to make the most of stock alerts in your Shopify store:

Set Up Low-Stock Alerts

These types of alerts notify you when a particular type of product will run out from your inventory. To configure these alerts in Shopify, use inventory management apps like Stocky, Inventory Planner, or built-in Shopify tools for merchants on advanced plans.

Define threshold levels for every product according to sales trends, lead times for restocking, and demand. By doing this, you can avoid missing out on sales chances by making sure your best-selling items are always in stock.

Use Reorder Point Notifications

A reorder point is the minimum quantity of products that you need to have before placing a new order.  For example, if your lead time is seven days and you sell 50 units per week, your reorder point should trigger when inventory falls below 50. 

By using reorder point notifications, you can automate the restocking process and guarantee a smooth supply chain with no store downtime.

Monitor High-Demand Stock

Stock alerts also help you understand about products that have a huge demand among your customers. Alternatively, you can track products that experience a surge in demand due to seasonal trends, promotions, or viral moments.

Stock notifications will let you know when such items are running low, so you can quickly restock and fulfil customer demand. Additionally, by recognizing popular products to further promote, these notifications help direct marketing activities.

Address Low-Demand Stock

Stock alerts can also notify you about items that are not selling well. These insights allow you to strategize, such as offering discounts, bundling slow-moving products with popular ones, or deciding whether to discontinue them altogether.

You can even integrate your Shopify store with apps that offer shipment alerts. These notifications ensure timely communication with customers about the status of their orders, enhancing trust and reducing the chance of disputes.

Customers are less likely to leave your store in frustration when stock notifications keep things from running out of stock. This promotes repeat business and fosters loyalty.

By leveraging Shopify stock alerts effectively, you can stay ahead of inventory challenges, improve operational efficiency, and deliver a superior shopping experience to your customers.
