multiple variants, different category and bundle

Shopify Discussion
1

Ok, so I’ll apologise in advance. Here’s my scenario.

I sell item A by weight and as part of bundles across different collections. Let’s say it is sold as:

  • Product 1 - 100g & 200g variants (in collection X)

  • Product 2 - 5kg & 10kg variants (in collection Y)

  • Product 3 (along with other unrelated items) - 100g and 200g (in collection Z)

I want to track item A where units on hand are the minimum quantity. So if I had 5kg on hand this would be:

  • Product 1 - 100g (50 units available) & 200g variants (25 units on hand)

  • Product 2 - 5kg (1 unit on hand) & 10kg variants (out of stock)

  • Product 3 (along with other unrelated items) - 100g (50 units available) & 200g variants (25 units on hand).

Is there an app, rule or way to set this up?

Hi @Dante_941 lot of moving parts there, could simply be inventory pooling or sync and customization.

That situation is very custom though most apps are not gonna have something to customize variants titles based including an arbitrary calculation.

Most bundle apps are not quantity maximum limits, or order limit apps etc.

If you ONLY want to change the variant titles to read out unit availability hypothetically this could be done in shopify flow if you spend the time figuring it out reading some shop variable of onhand weight to then update variant titles.

Realistically for titles , inventory sync, or order-limits you need a theme customization and or an automation app.

Either as above to change variant displays, or edit variant titles, and or limit quantities that can be added to a cart ,etc

For custom business automations see usemechanic, an example for syncing:

No specific task for the title editing use case but you can script it.

If you need this consulted on , automation or theme customization then contact me by my email for services.

ALWAYS please provide context, examples: store url, theme name, post url(s) , or any further detail in ALL correspondence.

Hi @Dante_941 :raising_hands:

Managing inventory across multiple package sizes of the same physical product can be challenging, especially when you need to keep stock levels accurate and avoid overselling.

If you’re still looking for a solution, you might want to check out Easify Inventory Sync. The app allows you to create Inventory Groups to link products and variants that represent the same underlying inventory.:blush:

  • Inventory Groups: You can place your 100g, 200g, 5kg, and 10kg versions of Item A into the same Inventory Group. This allows them to stay connected instead of being tracked as completely separate inventory items.

  • Automatic Inventory Sync: When one product or variant within the group is sold or its inventory is adjusted, the app automatically updates the inventory of the other linked products and variants. This helps eliminate the need for manual inventory updates across multiple listings.

  • Better Inventory Accuracy: Instead of managing separate stock quantities for each package size, you can treat them as part of the same inventory pool, reducing errors and helping prevent overselling.

It’s a practical way to manage a single product that is sold in multiple formats or package sizes while keeping inventory synchronized across your catalog.

Feel free to give it a try! If you need any help with the setup, the Easify support team is always available through the in-app live chat. :heart:
