Email Bill Delivery is not designed for emailing Reminder Statements on overdue AR. It is designed for sending out the initial Invoices only and, optionally, a Cover Sheet.

You may print Reminder Statements from Billing Manager > Print Invoices.  (If you leave the check boxes off the Print Invoices section and just check the options needed under the Print Reminders section you may print reminders by themselves).  See the articles Printing Reminder Statements and Printing Reminders.

Keep in mind you may email a Reminder Statement or any report in Orion, individually, by clicking on the email button on the Print Prompt or by choosing Export to PDF and attaching the pdf to an email.

If you need “en masse” email functionality for sending Reminder Statements or specific email “dunning letters”  on overdue AR, you may want to consider the AR Collections Manager, a module that may be purchased separately. Contact Orion support for more information.
