Statements are Not Automatic. You have to generate them. They are Hybrids of a report on a template (layout design) that you can customize. They are Run on Request and do not exist, otherwise.

There is no Automatic; this program doesn't know if you just got off the phone with someone who is coming by to Pay Now.

Here is what is Automatic: on Every Invoice Template you can Customize it and in the Footer, you can include the Customer's Total Balance, so that they see it when you email them. For instance, I have 84 "automatic" monthly (month end) invoices. Half of the customers are set up for email.
