Two different products, same SKU. Double inventory count?

Hi guys,

I have two seperate products, but due to the nature of them they need to share the same SKU.

Even if I enter the same SKU for the variants on the products, the stock count number still counts them as two different stocks when I look at my inventory count. Is it possible to link the products so that it shares the same inventory count, prefferably without the use of third party apps.

Two different products/variants will be viewed as different products. There's no native logic to consider those to be one and the same so for inventory sync you will need an app.

For context, why do you need to have two of the item in your store?

I would also like to do this - share inventory for variants of different products.

Jason, a possible scenario: (I saw it in another post) You print shirts, but only have 10 blanks size M, so all your shirt models' M size is the same SKU. Another scenario - sell shirts, but not all models have all sizes, so you create a product named "Misc design shirt" and put the deepest inventory SKUs from all your shirts. So customers choose - a specific shirt or the cheaper MISC DESIGN.

Anyone figure this out? I'm in the same boat with t-shirts. I carry an inventory of blank shirts that I use across different designs. I do not make the t-shirt until it is actually ordered and then pull from my inventory. I don't have shirts pre-made to sell. I would like the app to use the same SKU and when something is ordered in that blank shirt, it pulls it from inventory. Even though it LOOKS like two different products, it's not when it comes down to the blank tee. It would be nice to have two different sku's per product, one for the design (not necessarily to track inventory, but to track design sales I guess.) and the other for the blank tee.

Hey @customshirts @kal1 !


Trunk @ is is centralized inventory management that syncs stock levels in real-time between your Etsy, Shopify, Faire, eBay, and Amazon sales channels. It also supports smart bundles and kitting and can definitely do what you’re looking for. In Trunk, you would create your blank shirts (small, medium, large, etc) in your inventory and then have all your actual shirt product variants depend on it which then syncs with your Shopify listings in real-time.


Here’s a mockup I just did of how you would set that up within Trunk:

Some contributor is not answering the questions above.

Seems like people don't understand the concept of SKU.

SKU is the primary unique product itself. Regardless of how variants are different, if these variants share the same SKU, no matter how many of either variant are taken off shelf, the SKU total reduced accordingly.

It sounds like you could link products together that share the same SKU using this app

We use it to inventory adjust products that sell which are made up of other component products (eg a Hamper has a few of several other products that exist contained within it, and those products inventories reduce also when a hamper is sold), but I can't see why you couldn't use this app to connect two SKU products together (eg all matching SKU products would adjust when any of them are sold). However, you would need to create the relationship between the relevant products in the app, and it may become unwieldy to manage if there are many of these cases.

Hi Julkitchen02, 

Excellent! How does this work when adding stock though? Do I just add stock on one of the products and because the SKU is the same Shopify will deduct it where appropriate? 

e.g I have set up a clothing store

Orange top is on the SHOP ALL page and it also has variables (size and colour) within the product page i.e customer can select each colour.  Each colour variant is also on the shop page as a separate product however for the same colour and size they share the same SKU. How do I organise the stock?

I haven't had to account for this specific scenario before, so to more clearly understand this:

If you have a red tshirt and a blue tshirt, both with the same SKU, and they both have a stock level of 1, what would you expect to happen to the stock level when someone buys 1 blue tshirt?

Should the stock level of both go down to 0 stock? Or should there be 1 red tshirt and 0 blue tshirts left in the stock count?

@leeleeloo I have the same issue.

I'll try put it into an example and word it as good as I can because I feel like we have the same issue.

Product Name: Hero Pants
Hero Pants come in Black & Grey.
Hero Pants also come in Size S, M & L.

All Hero Pants that are Black and Size S have the same SKU
All Hero Pants that are Black and Size M have the same SKU
All Hero Pants that are Black and Size L have the same SKU
All Hero Pants that are Grey and Size S have the same SKU
All Hero Pants that are Grey and Size M have the same SKU
All Hero Pants that are Grey and Size L have the same SKU

I have duplicated the Hero Pants to reflect the same SKUs, Images, Quantity and so on. 

So technically, I have 2 Products just so I can shwo the different colours on the Collections page. Both have exactly the same SKUs but if a customer was to click on 1 of them and buy it, it doesn't update the inventory for the products that have the same SKUs on the other listing. If you have worked this out PLEASE LET ME KNOW! it's driving me insane! 

I don't get how this is not a shopify feature!

I'd use the following app:


It allows you to essentially designate a 'parent' product, and then link a bunch of other 'child' products to that specific product. This way, when any of the 'child' products are bought, the 'parent' product's inventory is adjusted. This is all the app does, and it won't affect the frontend in any way, just the inventory count which means you can test it properly without interrupting the customer experience. Hopefully that helps.
