Displaying Your Inventory Live on Your Website

Revealing your inventory to your customers in real-time on your website can greatly enhance their shopping experience. By providing accurate information about product availability and stock levels, you instill confidence and urgency in potential buyers. In this article, we will explore how to display live inventory on your website using Shopify.


Before we dive into the technical details, let's understand why live inventory display is crucial to your online store's success. When customers can see the exact number of items available, they feel a sense of transparency and trust. This transparency can motivate them to make a purchase promptly, especially when stock levels are limited. Additionally, it saves customers the frustration of adding out-of-stock items to their cart, only to find out later during the checkout process. By implementing live inventory display, you can create an optimal shopping experience for your visitors.

Displaying Inventory on Your Website

To begin showing live inventory on your website, you need to retrieve the inventory data from the backend of your Shopify product pages. This information is stored in the variants of each product. By accessing this data and dynamically updating it on the front end, you can showcase real-time inventory levels to your customers. In the following sections, we will guide you through the process of achieving this functionality step by step.

Shopify Product Pages

Before we start modifying our theme, we need to understand the structure of Shopify product pages. The product page template is where the information about a specific product is displayed to customers. In this tutorial, we will be working with the Dawn theme; however, the process can be adapted to any Shopify theme. The main product page file contains the "Add to Cart" button, which is the location where we will add our inventory counter. By customizing this file, we can achieve our goal without modifying the theme's main JavaScript file.

Duplicating Your Theme

To ensure that we don't disrupt the live version of our theme, it's always recommended to create a duplicate copy before making any changes. This way, we can work in a safe environment and test our modifications thoroughly. By duplicating our theme, we create a separate version specifically for implementing the live inventory functionality. Once the duplicate theme is created, we can proceed to edit the code and add the necessary logic.

Editing the Code

After duplicating our theme, we can access the code editor to make the required changes. Most Shopify themes have a main JavaScript file, usually named "global.js", where additional functionalities can be added. However, since this file structure can vary across themes, we will create the inventory quantity functionality from scratch in the product page file itself. We will locate the precise position in the code where we want to place our inventory counter and update the text accordingly.

Adding Inventory Quantity Functionality

To begin implementing the live inventory counter, we first need to understand the Shopify liquid language and how it interacts with the theme's files. We will use liquid logic to access the selected variant and retrieve its inventory quantity. By displaying different text based on the inventory level, we can provide real-time updates to the customer. The logic involves checking if the inventory quantity is less than or equal to zero, between zero and ten, or greater than ten. For each scenario, we will customize the text and emojis displayed to the customer.

Creating the Inventory Counter

To render the live inventory counter effectively, we will use HTML paragraph elements and assign a class to them. By selecting these elements in JavaScript, we can update their content dynamically. In our inventory counter logic, we will loop through all the instances of the live inventory count class and update the text based on the variant's inventory quantity. By changing the inner HTML of the paragraph elements, we ensure that the counter reflects the accurate number of available items.

Updating the Counter in Real Time

To achieve a seamless user experience, we want the inventory counter to update instantaneously when customers change their variant selections. By detecting variant changes in the front end, we can trigger the necessary code to update the counter. We will utilize JavaScript's event listeners to capture these changes and run a function that evaluates the old and new variant IDs. If a change is detected, the counter will be adjusted accordingly to reflect the stock level of the newly selected variant.

Comparing Variant IDs

To track variant changes accurately, we need to compare the old and new variant IDs. By parsing the URL query string, we can extract the variant ID and compare it with the previous value. If a difference is found, we know that the customer has selected a new variant. We will store the old variant ID in a variable and update it with the new variant ID every time a change is detected. This comparison allows us to update the live inventory counter only when necessary, reducing unnecessary updates and improving performance.

Updating Text based on Variant Selection

Once we have set up the logic to track variant changes and store the old and new IDs, we can proceed to update the counter text based on the variant selection. By implementing conditional statements, we can customize the displayed text and emojis. We will consider scenarios where the inventory quantity is zero or less, between one and ten, or greater than ten. By assigning appropriate messages and emojis, we can create a sense of urgency when stocks are limited and reassure customers when items are readily available.


In today's online marketplace, displaying live inventory on your website is vital for customer satisfaction and conversion rates. By following the steps outlined in this article, you can successfully implement a live inventory counter on your Shopify store. Your customers will appreciate the transparency and accuracy provided by real-time stock updates, leading to increased trust and improved shopping experiences. Don't hesitate to apply this functionality to your website and take your online store to the next level.
