Negative stock for customers

A client of ours has pointed out that they have negative stock for a number of products on their WooCommerce based store. The negative stock issue by clicking the ‘place order’ button at the same time using two different browsers.

I found that there is reply for this issue but when I used this plugin I found that the plug-in is for light usage

Are you planning to solve this issue? Or can you help me how can I solve this issue?
