I want to enable customers to be able to place backorders

In the docs its states for stock status of "Out of Stock" the following

Unless Backorders are activated, prevents the product from being available for purchase and removes the listing from the catalog."

This then implies I should set my products to be "Out of Stock" but enable backorders so I have the following settings as shown in the screenshot below:

The issue is that on the frontend the customer still is not able to purchase the product. See screenshot below:

I have tried to reindex and flushed all the caches but still no luck. Could any one advise?

Please enable backorder from configuration also:

Stores – Configuration – Catalog – Inventory – Product Stock Options tab:

  • The issue still exists unfortunately and as I have unticked "Use config settings" making any changes here won't have any effect surely?

  • Please have a look on this, might be it is related to your issue github.com/magento/magento2/issues/10304 Sep 17, 2018 at 11:12

Problem here is that stock status is out of stock, it should be ''in stock'' with qty 0 to allow back-orders.
