We generally do not pre-invoice based on a provided PO number. If you are required to go through a purchase order process we recommend the following procedure:
- Create a registration for your attendees.
- At the end of the process, choose Pay by Check. This will generate a confirmation/invoice number that can be referenced for your PO.
- When issuing payment, please send the corresponding confirmation number along with the payment so that it can be properly applied to your registration. If registering a group, you may use the group registration number generated at the end of your group registration to reference the entire group.
