Go to the WooCommerce Dashboard > Settings > Product > Inventory Page
From the Inventory Page The low and out-of-stock thresholds, whether or not out-of-stock items are displayed in the store, and how stock status is displayed in your store can all be customized by simply selecting the options from the selections.
Bulk Management
Go to Products > All Products and click on multiple products
Click on the Bulk Actions dropdown and change it to Edit and then click Apply
A bulk editing menu will appear. Click on the dropdown menu, select Manage Stock and switch it to Yes. You will have now enabled individual stock management for all the selected products.
Sold Individually
If you wish to sell just one item at a time, go to a product’s Edit page and navigate to the Inventory screen. Then, click on the checkbox for Sold Individually. The product level stock management feature does not need to be enabled for this.
