Manage inventory of Product Listed Multiple Times on Shopify

You’re running a successful Shopify store, selling custom-printed t-shirts. To maximize visibility, you create multiple listings, one for each design.

Everything seems fine until inventory chaos strikes.

A customer orders a design that’s out of stock, but Shopify still shows it as available. Meanwhile, another listing sells the same base product, and now you’ve oversold an item you don’t actually have.

Sounds familiar?

This is one of the most common inventory challenges Shopify merchants face in 2025.

And the reason is simple, Shopify treats each listing as an independent product, with no native inventory sync across duplicates.

If you’re manually updating inventory, mistakes are bound to happen.

Well, you can easily solve this problem with Sumtracker!

By assigning the same SKU across multiple Shopify listings, you can sync inventory in real time and prevent mismatches.

Let’s dive deeper into why this happens and how you can fix it effortlessly!

Why Managing Inventory Across Multiple Shopify Listings is Challenging

If you list the same product multiple times on Shopify, whether to showcase different designs, categories, or customer segments, you’re likely facing a huge inventory management challenge.

Shopify Doesn't Sync Inventory Across Listings

Shopify continues to treat every listing as separate. If you sell the same physical product under multiple listings, Shopify won’t automatically sync inventory. You’re left manually updating stock, which is inefficient and risky.

Overselling Causes Inventory Problems

Without syncing, customers can order out-of-stock products. This results in cancellations, refunds, and negative customer experiences, harming the store's reputation.

Manual Updates Can Lead Inaccuracy

Managing stock across 5, 10, or even 50 duplicate listings is nearly impossible manually. Delayed updates, human oversight, or mismatched SKUs are common causes of overselling and inaccurate reporting.

Automate Inventory Sync Across Multiple Shopify Listings with Sumtracker

To manage Shopify inventory for multiple listings, sellers need a real-time inventory syncing solution.

Instead of manually updating stock for every listing, Sumtracker allows you to link SKUs across different listings. This means if one listing sells out, the stock updates across all related listings instantly.

By using Sumtracker, Shopify sellers can efficiently track stock for the same product across different listings, prevent overselling, and ensure smooth order fulfillment. Automating inventory updates eliminates manual work, reduces errors, and keeps customers happy.

Example Scenario

Let’s say you sell 100 black t-shirts but list them separately for different printed designs.

Without SKU Linking: Each listing shows 100 in stock. A customer buys from one listing, but the others don’t update. You end up overselling without realizing it.

With SKU Linking in Sumtracker: All listings share the same SKU. If one t-shirt sells, stock updates to 99 across all listings instantly. No stock mismatches, no overselling.

What This Means for Your Business

• No more stock discrepancies. Every listing reflects the correct inventory in real time.
• No more manual updates. You save time and eliminate human error.
• No more overselling. Your stock remains accurate across Shopify and all other platforms you sell on.

Setting Up SKU Linking for Multiple Listings in Sumtracker

Follow these simple steps to manage Shopify inventory for multiple listings:

Step 1: Identify Listings That Share the Same Product

Find all listings that represent the same physical product. Examples:

• Custom t-shirts with different prints
• Cosmetics sold in bundles and as singles
• Electronics accessories under multiple categories

Step 2: Assign the Same SKU to These Listings in Sumtracker

Inside Sumtracker, go to your product catalog and find the listings that represent the same physical product. Assign the same SKU to each of these listings so that they share inventory.

Once the same SKU is linked across multiple listings, Sumtracker will automatically track stock as one unit instead of separate quantities for each listing.

Step 3: Enable Real-Time Stock Sync

Once your products have the correct SKUs, you need to activate real-time syncing in Sumtracker’s settings.

• Go to the Inventory Settings in the Sumtracker dashboard.
• Turn on real-time stock sync for all connected platforms.

For example, if you have 100 units of a product and a customer buys from one listing, stock updates to 99 on all linked listings in real time. If you restock inventory, all listings will reflect the updated quantity immediately.

Step 4: Verify Inventory Updates & Go Live

Once SKU linking is set up, test it by making a test sale on one of your linked listings. Then, check your Sumtracker dashboard to ensure that the inventory count updates correctly across all other linked listings.

Once confirmed, your inventory syncing is fully automated, and you no longer have to manually update stock levels for the same product listed multiple times.
