How to manage inventory when a product can be bought in different size (batch, or singular item)

[Gabriele_HK]

Our store is having products which can be bought in different sizes: 

1. Singular Packaging
2. Pack of three 
3. Box of fifteen

We want to be able to give the customer a choice to buy the product in three packaging but we also want to make sure the inventory is synced. So if a customer buys the product in batch the other options are becoming unavailable. 

Is there an application for this or native setup in Shopify?
