From the Commissions App you can quickly create quarterly commissions statements to assist with tax, BAS and other reporting requirements.

Head over to Commissions > Commission Statements and simply drag the columns you want to group into the task bar.

This will create an expandable summary row, including the total for each group.

You can change the grouping, by changing the order you add items to the task bar.

You can also use the filter to eliminate unnecessary data.
