How to set a base inventory for all products and options

Shopify Discussion

Topic summary

Managing shared inventory for “Black Frame” options across all products, so a single A3 frame stock count updates no matter which product it’s sold with.

Proposed solutions (app-based):

  • Bundling approach: Use a bundle app to tie each product option/variation to the same SKU (stock-keeping unit) across products, so inventory decrements from a single source when any linked variation sells.
  • Product-options approach: Use an options app to create “Black Frame” as a custom option, manage frames as a separate product with size variants and quantities, then link option values to those specific variants so stock syncs automatically.

Implementation details highlighted: create frames as a separate product with size variants; link options to those variants; screenshots provided to illustrate setup (images not essential to understand).

No built-in Shopify method was confirmed; third-party apps are the recommended path. No final decision or resolution from the original poster; discussion remains open.

Hi Miki

You achieve this by bundling up each variation so that way you can link the same SKU to multiple variation items across different products and update inventory accordingly.

Happy to help you set things up using our bundle app so you can see how it functions.

Regards

Tom
