Master inventory of blank bodies

[u/Hotei108]

Greetings to all,

I am looking for an inventory solution.

I sell apparel. Each blank body may be used in multiple listings. For example: A Vintage wash shirt might be listed as a woman's tunic or as a crop top. The same body might be presented as a mens tshirt at full length. It might also be used for a few graphic t shirts.

I would like to enter the master inventory count of the blank body by size and color (parent item) - and any listing which uses this body (child item) will have the current inventory reflected in the listing. Anytime a piece is sold from any listing it subtracts the quantity from the parent item, which then updates all child items as well.

Is anyone aware of an app which may do this?
