Hello, I run a Retail & Wholesale CS Cart Store, using user groups.
Last Friday a Wholesale client purchased the last remaining items of a product.
Today I log in to the dashboard to find out that the item quantity hasn't changed.
I also see quite often, that although the physical products are inserted with care, in terms of the number of items, the CS Cart warehouse doesn't remove from stock.
I am looking to investigate further, or even hire someone to apply a fix.
Please check order statuses log on the Administration -> Logs page for this order. As said himanshudangwal, in stock value is changed only if previous status has another value of the Inventory value (Decrease->Increase or Increase->Decrease)
