School Systems: All your attendees who have registered for the conference/meeting will show on the invoice. If they are not registered for the conference/meeting they will not show on the invoice. An invoice can be printed by School System or School. Once you have selected your school and entered your PO. number click submit and your invoice will be generated. The invoice will have a list of all the attendees registered under your school or school system. If there is a name on the list that should not be there check the box next to their name and click submit and they will be removed from the invoice. Once you have verified the invoice you must submit your invoice by clicking the "Submit Your Invoice" button (top right corner) and either pay by card or school system check. If you pay by check make sure to send a printed copy of your invoice with the check.
