After scanning an item bar code for a sale transaction, and if the item has insufficient available stock due to inventory discrepancy, a message window will pop-up to notify the cashier.

• Cashier can still proceed with the sale by clicking on “Yes” button.
• The Inventory Stock will be reserved but the posting of the Point of Sale Invoice (generated automatically after daily closing) would not be possible because of the missing quantities in the inventory. A stock adjustment will have to be made for the missing quantity before and then only would the POS invoice be postable.
