When you don't manage the inventory now, you want to keep sending out orders with products with no stock. To do now now we first have to update the product stock before we can send out an article with no stock in Magento. Is it possible that we can send out items with no stock?

If you just want to be able to create shipment for all items in orders for even if they are out of stock items, so we suggest you can change product to be No manage stock. Then you can create shipment for these items.

To change a product to be No manage stock. Please go to backend > product detials > inventory advanced > select manage stock = No and save the product
