Magento 2 Add to cart out of stock item issue

Question

I have a product with 0 quantity and Out of Stock Product, and it is showing on front-end. Customer is able to do add that product to cart.

I run all commands like:

php bin/magento indexer:reindex
php bin/magento cache:flush
php bin/magento cache:clean

but issue not solved.

Please tell me the appropriate solution.

Answer 1

The command that you have used for reindex is wrong. Please use

php bin/magento indexer:reindex

Also check the value of

Stores->Configuration->Catalog->Inventory->Stock Options->"Display Out of Stock Products" is 'NO'

and the value of

Stores->Configuration->Catalog->Inventory->"Product Stock Options"->"Out-of-Stock Threshold" is zero

if you are using Magento 2.3

Answer 2

After alot of research, I found the solution.

System configuration was wrong for Backorders.

Now I make it like this:

and it makes my day :)
