Can you sell individual size items made up of one sku?

[NNSunderland]

We sell jewellery on our store - a bracelet is made up of individual single link components which range from size 13 up to size 23? Is there a way I can offer this for sale on my shopify site where the customer only sees the size options (doesn't see the individual link components) but from a stock perspective our system uses the quantity of individual links ? 

example:

A customer wants to buy a yellow coloured link bracelet at 18 links

They currently select an 18 link bracelet with sku 030091/008/018 (variant of sku 030091/008) and Select an second bracelet at 15 links with sku 030091/008/018. Both of these show in our inventory currently as different options but we would like to run from a main (root) sku.

Hi @NNSunderland,

The app Material Manager can achieve this. It works by letting you enter a separate inventory for your raw materials and then link the amount of materials used in each of your variants.

For your example it would work as follows:

• Enter a raw material inventory of bracelet links into the app (lets say with a quantity of 100)
• Then within the app link your 2 variants to the material. Specifying one uses 18 links and the other uses 15.
• If an order goes through with one of each variant the link material inventory will be updated to 67 (100 - 18 - 15 = 67).
• The Shopify variant inventory for the 18 link will now be 3 and the 15 variant will have an inventory of 4. As this is the max that can be created with the remaining raw material inventory.
