NOTE: if you have variable registration prices defined such as an early bird rate, when the deadline date passes, there will be unpaid, incomplete attendee invoices that will contain the early bird price. If you wish to update the unpaid, incomplete attendee invoices and remove the early bird price and replace it with the current registration price, use Batch Invoice Update. If you do not wish to update the invoices, the early bird pricing on the invoices will be retained after the deadline date for the rate has passed.
