I need to urgently improve my inventory management as I am constantly running out of stock! I am hoping that there is an app that can track inventory based on bundle sales.
We basically sell two skincare products, available in various bundles with different accessories. Currently, managing inventory for these bundles is challenging because I have to manually update each item’s stock.
I’m hoping there is an app that can simplify this process. I don’t want to create new product skus, I just need an app that automatically tracks each sku when a bundle is sold, so I am on top of ordering more stock.
You can try apps like Stock Sync, Realtime Stock Sync & Bundling by Trunk, Katana, Skubana, and ShipHero.
If nothing meets your needs, there is always a way to develop a custom app.
We have a great solution that might be just what you’re looking for! Our Product bundles app is completely free and lets you create a variety of offers and bundles, including the “grouped offer.” Here are some of its standout features:
No need to create new product SKUs: You can directly link this offer to any of your existing products to create a grouped bundle.
Streamlined inventory management: When a bundle is added to the cart, each item is added to the cart as a separate product. This ensures that stock levels are automatically updated, keeping all the native features of your store intact.
Unlimited flexibility: You can add an unlimited number of products to each offer, giving you the freedom to customize bundles as needed.
Here’s the screenshots to show you how these products appear on the storefront:
You may find our app as a solution to address your bundle inventory management. You can sell your existing Shopify product SKUs as a single product or as part of the bundle without the need to create separate SKUs. For the bundle product, that will be the bundle in the app, you might need to create a new SKU, but this won’t affect your child products at all.
Simple Bundles also uses the lowest product inventory quantities to keep the bundle inventory quantity in sync. This means that to prevent overselling, bundle inventory is calculated based on the number of bundles that can be created using the available child product inventory quantities. If you sell any of the items individually, the bundle will recognize the updates in the inventory to discount the stock available. You can learn more about how we handle the inventory here: Automatically update bundle inventory - Simple Bundles Help Center.

We definitely can help with tracking each SKUs when a bundle is sold.
The Easify Inventory Sync app could be a great solution for your inventory management needs . The app allows you to create a bundle group in Shopify admin, which includes your main product and its accessories, and then syncs their inventories. For instance, you could create a bundle group for your Skincare product A with its accessories as follows:
Master product: Skincare product A
Component products: Accessories 1, 2, 3 (You can also specify the quantities of each accessory that contribute to the bundle).
As a result, whenever Skincare product A is purchased, the quantities of the accessories will automatically be deducted based on their preset quantity per bundle.
If the accessories are fixed, this approach will work well. However, if you allow customers to choose from different accessories, I can suggest an alternative solution.
Late to this one, but it’s still a top result for anyone searching this exact problem, so it’s worth a real answer instead of another app-name drop.
The reason none of the suggestions above quite match what you asked for: most bundle apps keep a separate inventory count on the bundle product itself, and either sync it to the components on a timer or expect you to manage it by hand. That’s the duplicate-SKU problem you’re trying to avoid — you end up with a bundle number that can drift from what’s actually on the shelf.
The alternative is a bundle that checks live component stock at checkout instead of keeping its own counter, so there’s nothing to sync and nothing to drift. To be clear about the limitation: you still need one product listing for the bundle itself — Shopify requires that for it to be a sellable thing with its own price — but the inventory maths isn’t duplicated. If a component runs out, the bundle reflects it immediately rather than on the next sync cycle.
I built one that works this way (Solid Bundles) after running into this same complaint over and over while researching the category. Free plan if you want to kick the tyres, but the mechanism above is the part worth knowing either way — it’s the thing to ask about whichever app you end up choosing.
Worth adding the free first-party option here: Shopify’s own Bundles app does exactly what the original post asked for. You build a bundle from your existing products, no new component SKUs, and when a bundle sells Shopify deducts each component’s stock in real time. Bundle availability is calculated from live component quantities too, so the bundle shows out of stock the moment any part runs out. No separate counter, no sync timer to drift.
When a bundle sells, it automatically decrements every individual SKU underneath it in real time. No manual updates, no new SKUs needed, it just tracks everything across all your bundles simultaneously.
So if the same skincare product appears in three different bundles, Nventory knows exactly how many you have left across all of them the moment anything sells.
You can also set low stock alerts so you get notified before you run out which sounds like exactly what you need right now!
every answer here assumes you need a bundle product first, which is the exact bit you said you didnt want. theres a second shape that rarely gets mentioned: dont create a bundle product at all, and put the offer on the cart instead. product a, product b and the accessory go in as normal lines, and a discount function applies the bundle price when the right combination is there. inventory is then just your existing skus decrementing normally — nothing to sync, no second stock number that can drift from whats on the shelf.
what you give up is real though: theres no single bundle listing to send traffic to, no bundle product page, no bundle sku in your reports. if you advertise the bundles as products (ads, collections, a link you can send someone), you want the componentized route instead — thats shopifys own free Bundles app, it builds the bundle out of your existing products, decrements each component on sale, and works out bundle availability from live component stock, so theres no extra sku for the parts either.
so the question that actually decides it is: do you need the bundle to be a page someone can land on, or just a price that happens when the right things are in the cart. first case native bundles, second case a cart level offer. disclosure, i build a cart app (verve) that does the second kind and its free right now.
The thing to pin down first is how each app handles the inventory, because there are really two designs and they behave very differently.
One design makes the bundle its own product with its own SKU, then runs a background sync to knock down the component stock after each sale. Clean reporting, but the sync can lag and oversell during a rush. The other design keeps no bundle SKU at all. The bundle is just your existing products going into the cart as separate line items, so Shopify decrements each real SKU natively at checkout. That second one is what you’re describing, no new SKUs, and stock just works off your existing products.
Disclosure: I build EZBundle, which uses that second approach. Fixed bundle of your two core products plus accessories, each item is a real line item, the discount applies at checkout, and inventory comes off each component’s own stock. It never creates a bundle product or a separate SKU to keep in sync.
One honest tradeoff so it’s not a surprise: because the items go in as separate lines rather than one locked bundle unit, a shopper can remove a single item from the cart, and you won’t get a single “bundle sold” line in reporting the way the bundle-SKU approach gives you. For a skincare kit that’s usually fine, but if bundle-level revenue reporting matters more to you than native stock, the SKU-based apps in this thread lean the other way.
Whatever you try, test it with a real order before you trust it. Buy a bundle yourself, then check that each component’s stock dropped by the right amount at the right location.
Hello, @luisanotetoself
Hope this message finds you in good spirit!
If you don’t want to create separate bundles SKUs, I’d recommend looking at Simple Bundles & Kits, Shopify Bundles, or Bundle Kit. These apps support component inventory tracking, meaning when a bundle is sold, they automatically deduct the inventory of each individual SKU included in the bundle.
Two years on and this thread still ranks for the exact problem, so it’s worth answering the mechanism rather than dropping another app name.
Your constraint — “track each SKU when a bundle sells, without creating new SKUs” — comes down to one design question: does the app keep a separate stock number on the bundle, or does it read your components’ live stock?
If it keeps its own bundle counter, you’re back to the drift you’re trying to avoid — the bundle number and your real shelf stock slowly disagree, especially since your two skincare products also sell solo and sit inside several bundles. What you want is the bundle’s availability derived from the scarcest component: “how many complete sets can I build from what’s actually on the shelf right now,” recalculated the moment anything moves — a bundle sale, a solo sale, a restock, a refund.
One honest caveat so it’s not a surprise: Shopify still needs one product listing for the bundle itself to have a price and a page — that part’s unavoidable. But that’s just the listing; the inventory math doesn’t have to be duplicated. Your two SKUs stay the single source of truth and decrement natively.
Full disclosure, I build in this space — my app is BundleSafe, which maintains exactly that “bundle available = scarcest component” invariant live on every event. But whatever you pick, the question to ask any vendor is: “when a component sells on its own, does the bundle availability update in real time, or on a sync timer?” That one answer separates the apps that prevent oversells from the ones that just detect them later.
Shopify launched the cart transform API for all bundle app developers. Most of us are using it to build the bundle apps. When a bundle is sold, the bundle components (i.e. the individual SKUs) inventories are updated in real time. The orders will also show the SKUs.
There is only 1 bundle parent product created to show on the cart. I think Shopify has fixed your issue
. The app allows you to create a bundle group in Shopify admin, which includes your main product and its accessories, and then syncs their inventories. For instance, you could create a bundle group for your Skincare product A with its accessories as follows:
