When i have checked in admin panel...
Please help me out..
Thanks in advance...
Check below settings.
Admin > Store > Configuration > Catalog > Inventory > Stock option > Decrease Stock When Order is Placed Set it to yes.
If you have a multi-website or multi-store then change the same setting for all store.
check your stock setting in admin panel Advance Inventory->manage stock set to yes if you want to reduce quantity
It seems you guys have been working on 2.3.0, where the default QTY will be reduced upon shipment.
M2.3.0 has released a feature know as Salable QTY which will be reduced upon placing an order.
QTY of product will updated after create Shipment for Order.
