Hello Odoo community.

My goal is to make two or more sellable SKUs that both deplete the same physical inventory item. Example: “iPhone 12 Screen” and “iPhone 12 Pro Screen” should pull from a single shared stock item.

Goal

Two sellable SKUs for Sales, Invoices, Website, and POS.

One stock item controlling on-hand, reordering, valuation, lots/serials, and cost of goods.

Current idea

Use Kit BoM (phantom):

Each sellable SKU is a front-facing product that explodes to 1× shared component (the real stocked product).

Inventory and valuation tracked only on the component.

Questions:

Is Kit BoM the right approach in Odoo 19?

Should alias SKUs be service or storable?

Any issues with lots/serials, returns, POS barcodes, or accounting?

Any cleaner native solution?
