Hi @5d970acbb8c78 

I didn't get your question properly.

Magento already managed qty deduction after place order by default.

No, I want to update the ordered product stock with some custom quantity.

Enable the Manage Stock option to control and keep track of the number of items currently in stock. Select the way you'd like to manage Backorders. Enter the Maximum Qty Allowed in Shopping Cart to determine the number of products per one order.
