A merchant needs to track inventory for a product sold in multiple pack sizes (individual, 10-pack, 20-pack, 30-pack, 50-pack, etc.) that all draw from the same stock pool. When a customer purchases a 30-pack, the system should deduct 30 individual units from total inventory rather than treating each pack size as separate stock.
Recommended Solutions:
Several inventory management apps were suggested:
Connected Inventory – Syncs multiple variants to a single stock count
Bundle Kit – Automatically adjusts inventory for different pack sizes
Sumtracker – Tracks inventory across variants with automatic stock adjustments
Material Manager – Allows linking variants to a base material with specified quantities
Qoblex – Creates bundled products that pull from master inventory across sales channels
Easify Inventory Sync – No-code solution using a draft base product with bundle groups that automatically recalculate available quantities
All solutions work by creating a master inventory pool and configuring each pack variant to deduct the appropriate number of units when sold, preventing overselling and eliminating manual inventory updates.

I’m in need of a inventory tracking app or add-on that will take my 5-6 variants and be able to combine them all into one large inventory.
For Example:
My store has individuals, 10 Packs, 20 Packs, 30 Packs, 50 Packs, etc. of the same product, but they are all sold at different prices depending on how much is bought.
My question is, is there an app or add-on that I can have where I can put in the total number of units in and if a customer buys a 30 Pack, it only takes 30 pcs out of inventory, or the 50 pack takes 50pcs out of inventory from a total number of stock?
Hi @diamondprotect , the app Material Manager is able to do this. You would enter your single item as a material in the app then you can link each variant to it specifying how much of it the variant uses. The app would then take care of syncing all the inventories.
Qoblex can definitely help with this! Our inventory management system lets you create bundled products (like your 10, 20, 30, and 50 packs) that all pull from the same master inventory.
Here’s how it works:
You input your total stock of individual units.
Each pack (e.g., 10-pack, 30-pack) is set up as a bundle that deducts the correct number of units when sold.
When a customer buys a 50-pack, Qoblex automatically reduces your total inventory by 50 units—keeping everything in sync across all your sales channels.
This way, you don’t have to manually update inventory for each variant, and you reduce overselling risks. Check us out on the Shopify App Store!
I recommend Easify Inventory Sync. It’s a no-code solution that lets you sync inventory across multiple variants. When a customer buys a 30-pack, it automatically deducts 30 units from the total stock—keeping everything accurate and hassle-free. Here’s how it works:
1. Create a Base Product: Set up your single item with for inventory tracking, this product will be a Draft and won’t be visible in the storefront.
2. Set Up Bundle Groups: Use the app to create a bundle group that connect your packs variants with your single item. Here’s how to set up a bundle group for your product:
Master Product: 10 Packs variant
Component Product: Single item, with the Quantity per Bundle set to 10
3. Do the same with 20 packs, 30 packs, 50 packs, etc.
4. How It Works:
When one pack is purchased, the single item’s inventory will automatically be reduced by the corresponding number.
When one ‘10 packs’ is purchased, the single item inventory will be reduced by 10. The app will then recalculate the available quantities for your packs based on the updated single item inventory, ensuring accurate inventory tracking.
