Linking inventory to multiple products

1 0 0

I sell 8 products individually and also sell those 8 products in a 4 pack, an 8 pack and a customers choice of 3. How do I connect my total inventory to the 8 individual products to be accurate when the packs are sold

As Shopify doesn't have a native bundling solution you can use a bundle app to map the packs against the single products. If the packs are preset then you can use a backend driven app like bundleup. There are 2 main function of our app:


1. Inventory Management

Our app lets you connect up products to correct SKUs and we then update their inventory based on the component stock level. So in your example if you have 4 different SKUs as part of your 4 pack you map these and the stock of the pack will be dependent on how many you can make up from the individual stock levels.


2. Order Fulfilment

When you sell one of the packs the individual stock levels won't reduce automatically. What our app does is update the order post purchase by replacing the order line with the Single SKUs as order lines which then reduces that stock. This then feeds into point 1 above where it updates all linked packs.


Another popular way is to set up pack size as an option of the single product. But this would mean the packs is made up of the same SKU.


If you need help in setting up and testing please get in touch. You can also find our guide here:

Hi @David_ausgardo 


This is Jun from Bundle Kit


Our app is able to meet your needs as it is primarily a bundle inventory management system so it will also be able to track the SKUs for variants of each product.


The bundle inventory is automatically set based on the available inventories of the bundle item(s), including the inventories of the variants. Proper quantity will also be taken out of the inventory of each bundle that is being purchased.


You can create bundles using our app. We have step-by-step instructions here:
