To view your monthly invoicing totals, go to Invoicing > Monthly Totals.

The Monthly Total screen will open - here you will have an overview of your unpaid invoices broken down by staff as well as the percentage of the total unpaid amount. 

When an invoice is marked as paid, you'll be able to see an overview of each monthly total here. 

Note: To mark an invoice as paid, navigate to the client file and select the Invoices tab. 

From here, you can use the Paid column along the right of each invoice to mark it as paid. This will update the monthly totals and client debt.
