By installing this module in your store, these changes will occur:
If the customer requests to buy more than the inventory, he will not allow the customer to buy.

And if the product balance is equal to 0, the "add to cart" key will be hidden and you can no longer add that product to the shopping cart.


install:
First, download the Zip file.
Then go to Extensions>Installer and click the "Upload" button.
Then select the downloaded Zip file and upload it.
Go to Extensions>Modifications and click on the (refresh) button on the top right of the page to update the new changes in your store.
