To view a discounts report, go to Reports > Financial > Discounts.
A discount report gives a quick overview of applied discounts. Using the filters, you can view the discount information you are interested in. For example, you can view the discount information of a specific discount type or discount scheme.
Using the Group by filter, you can organise the report data by item type, sub-group, item, or client depending on how you want to view the data or what grouping works best on your data.
