Hi,
Yes. In your HikaShop configuration page, you have the setting "Update the product stock on confirmed status".
If it's set to "created", the stock will be modified when the order is created right at the end of the checkout.
If you set it to "confirmed", then the stock will be modified when the order's status is changed to "confirmed".
So with the check payment method, you usually change the status of the order to confirmed, after you clear the check:
