Access Reports > Accounting > Sales. Complete the search criteria for your report. When an adjustment has been entered for an item (e.g., add discount, write-off), the sales report displays a zero within the Qty column and a negative preceding the adjustment amount in the Adjustments column.
Example: A pair of glasses were sold last month. The day of the transaction, the Sales Report displays one in the Qty column and the dollar amount of the sale in the Gross column. Your practice receives payment, and a write-off is entered for that item. The sales report for the day the payment was processed displays zero in the Qty column and a negative dollar amount for the write-off in the Adjustments column.
