How inventory can work with the bundle products that are added to the cart as a single product?

You may have made a product from your bundle (combo product) with the Fast Bundle app and set it to be added to the cart as a single product (not adding included products to the cart).

With such a bundle product, when you click on the add to cart button the bundle product itself will be added to the cart.

In this case, an important question is how the included products' inventory level will be handled. There are 3 ways to handle the inventory.

1- The default behavior is when such a bundle product gets purchased, we decrease the inventory level of each included product by the number of items of that product in the bundle. In the above example when the "Black Friday Set: Lee Straight Jean + Lexie Shirt" product gets bought by a user, the inventory level of the "Lee Straight Jean" and the "Lexie Shirt" will be decreased by one automatically and the order will not have any changes. The order will be like the below image:

2- Another option that you can tell us to enable for you is when such a bundle product gets purchased, the included products in the bundle get added to the order along the bundle product after the order gets placed with 0 prices. In the above example when the "Black Friday Set: Lee Straight Jean + Lexie Shirt" product gets bought by a user the order will be changed like the below image:

3- The last option that you can tell us to enable for you is when such a bundle product gets purchased, the included products in the bundle get added to the order with their discounted price, and the bundle product gets removed from the cart. For example, when the "Black Friday Set: Lee Straight Jean + Lexie Shirt" product gets bought by a user the order will be changed like the below image:
