The Sales by Product report displays sales information by each product sold. The report has cash drawer filters, so that you can restrict the results to see what has sold at an individual cash drawer. The Sales by Product report also allows you to filter by the time of the day, so that you can even tailor the report to match a certain staff member's shift. You can find more information about this report here.
