You can do recurring invoices and recurring statements.
To do an invoice, you would select "Save as Recurring" in the Record drop down menu when you create the invoice. Then there is an option to Run Recurring Invoices from the Tools section of your menu bar.
To do a statement, there is an option to run automated statements on the sidebar. This will pop up a box asking if you want to email or print them.
I have no need to do either so I can't speak from experience on this one, but I have briefly explored these features. For more help, go to your Help menu and look at the User's Guide. Here is a link to that: http://help.nchsoftware.com/help/en/expressinvoice/win/index.html
Hope this helps!
