Hi,

You can create custom filters to sort the invoices in non-paid stateeg:Invoices -> filters ->unpaid

By choosing the unpaid filter you can get all the unpaid invoices

And also you can add a custom filter for filtering the records based on the due dateFor that click on the "Add Custom Filter" and add your filter for the due date

And after that select all the filtered records -> Print -> Invoices to print all invoices

Hope it helps
