The NET PAYOUT column in MOBILE can display your profit for selling the item once the COST of the item is entered. With a long press of the BUY button a QTY and COST pop-up will appear in which you can enter quantity and cost associated with the item. Once COST is entered, that amount (your cost) will be deducted from the NET PAYOUT column.
First scan the item. NET PAYOUT results do not include your cost at this point. Press and hold the BUY button.
The QTY and COST pop-up will appear in which you can enter quantity and cost associated with the item. For example, I entered a QTY of 1 and a COST of $1.00.
After clicking OK the main screen will appear and the NET PAYOUT column will now take into account your COST - indicating your PROFIT should the item sell at that specific price. As you can see, the NET PAYOUT column is now reduced by my COST, which is $1.00.
