sharing viariant inventory across multiple products and limiting the options

Shopify Discussion

Topic summary

A gift box business owner needs to manage shared inventory across multiple box designs while limiting customers to selecting only one add-on per box. When a customer chooses a gift variant (e.g., Variant 1) in any box design, the inventory should decrease across all product listings.

Recommended solutions:

  • Connected Inventory or Bundles.app: Link variants across products with shared inventory tracking and enforce one-gift-per-box limits
  • Gift Box Creator app: Supports limiting selections but does NOT natively sync inventory across multiple listings
  • Bundle Builder by Agile: Handles dynamic bundles with conditional logic (e.g., 2-pack selections) without creating excessive SKUs, though pricing may be a concern
  • Easify Inventory Sync (under $20/month): Uses grouped inventory feature to pool the same gift items across different boxes, automatically deducting from shared stock when purchased

Additional challenge: The business owner wants add-ons to appear together with the main product in cart (not as separate line items) while staying within a budget under $20/month.

Status: Discussion remains open as the owner evaluates budget-friendly options that consolidate cart display.

i have a gift business where you pick a box and fill it with one gift. i dont want the customer to have the option to choose multiple add-ons per box, so the variant seemed easier. however, the variant inventory is shred amongst the 6 different box design options. is there an app that helps with both needs?

box A OPTION: (ONLY ALLOW TO CHOOSE ONE)

VARIANT ONE

VARIANT TWO

VARIANT THREE

box B OPTION: (ONLY ALLOW TO CHOOSE ONE)

VARIANT ONE

VARIANT TWO

VARIANT THREE

And so on. if the customer chooses variant 1 in box a, i need the quantity to go down across all listings.

Hi @bigfeatures ,

You can use the Connected Inventory app or Bundles.app on Shopify. These apps let you:

  • Link the same gift variant across multiple box options (shared inventory).

  • Limit customers to selecting only one gift per box.

So if Variant 1 is chosen in Box A, its stock updates across all box options.

thanks, would this app do the same? https://apps.shopify.com/gift-box-creator

  • Link the same gift variant across multiple box options (shared inventory).

  • Limit customers to selecting only one gift per box.

Limit to one gift per box – Yes, it supports allowing customers to choose a limited number of gifts per box (you can set it to 1).

Shared inventory for the same variant across multiple boxes – No, it doesn’t natively sync inventory across multiple product listings using the same gift variant.

For shared inventory across multiple listings, you’ll still need an app like:

  • Connected Inventory

  • Bundles.app

ok, this option is creating way too many skus. what app is best for this example? looks like i need something that creates combos

select a box (6 designs, main product)

choose an add on

heres an example of one category of an add on:

seeds

1 pack or 2 pack

options: poppy, lettuce, pears. ideally, if customer clicks 2 pack then they should be able to select 2 of any of the seed options.

Use Bundle Builder by Agile — it’s ideal for:

  • Letting customers pick a box + one add-on

  • Conditional logic (e.g. 2-pack = choose any 2)

  • Shared inventory across all bundles

  • No SKU overload (uses dynamic bundles)

Hi @bigfeatures

You can try using Easify Inventory Sync, which supports shared inventory tracking through its grouped inventory feature. This allows you to group the same gift item across different box designs, so even if it’s shown in Box A, Box B, or others, it will pull from the same inventory pool.

This way, when a customer selects a gift in any box, the inventory for that item is deducted, preventing overselling while still letting you control how options appear per box. Here’s how it works:

1. Create products: set up your 2 products with variants in Shopify

2. Set up an Inventory Group: Use the app to create Inventory Groups that group your 2 variants (Variant One in box A and B; Variant Two in box A and B; Variant Three in box A and B), and set mutual inventory

3. How does it work? When variant one in box A is purchased, both variant one in box A and B will be reduced by 1 (or you can say the shared inventory will automatically be reduced by 1) ensuring that the inventory of your shirt is tracked.

This app is very beginner-friendly, I hope you will try it. If you need any further assistance setting this up, please let me know or reach out to Easify! :hugs:
