How to keep selling out-of-stock products in WooCommerce

For example, if a product has variable items (like in color or size) that are still in stock and you need to sell them.

This feature can be enabled under the Per-Product Inventory Options.

  1. From the WordPress Admin sidebar, please, navigate to Products and select one item to edit.
  2. Scroll down below the post editor to find the Product Options panel and click the Inventory tab.
  3. Check the Enable stock management at product level in Manage stock option.
  4. There you will see the Allow Backorders setting. Select Allow from the drop-down list and update.

If you wish to continue selling a variable product, you should also verify the stock of each variable item and make sure you have all your variable items linked.
