robertodimarco on "[Plugin: WooCommerce - excelling eCommerce] Update inventory after clicking on 'buy' button"

Hello! Sorry for English, I used google translator.
I need help : in my shop I sell unique products. I noticed that the inventory reports out of stock only after the customer has made checkout.
I need to report "out of stock" immediately after the customer has clicked on the button "buy." How can I do? Thank u
