If you are invoicing through Conference Manager and an order has an unpaid invoice where the payment deadline has been exceeded, you can send a reminder directly from the invoice list.
Go to Participants → Invoice list and select the invoice you want to send a reminder for. Click Send reminder in the toolbar. A confirmation window will appear – click Continue to proceed. The reminder email will open, where you can edit the subject line and the text if needed, or use a template. When the content is ready, click Next step. In the final step, choose whether to send the reminder immediately or schedule it for later, then click Send/Schedule.
The reminder will then be sent to the order responsible person on the selected invoice.
