How to create a report for all invoices that are overdue

You can print a report for all outstanding invoices by going to 'Reports Menu'/'Expense Reports'/'EXP003 - Accounts Payable Overdue'.

This report looks at the payment due date on invoices, then shows invoices were there is a balance owing and the payment due date is less than the end date of the report. If no payment due date has been set, this means this calculation cannot be performed, and therefore the report shows blank. To fix this, simply open the invoices and set a payment due date, then rerun the report.
