You need to automatically confirm delivery order. That way, when you confirm a sales order, the delivery order created will be confirmed as well and the inventory will be deducted. To automatically confirm delivery order, you can try creating an automated action or use third party modules. I'd always go to my trusted Cybrosys before trying any other providers or code them myself: https://apps.odoo.com/apps/modules/17.0/sale_purchase_automated
