Are purchase orders an acceptable method of payment?
IIE accepts purchase orders as payment for conference/seminar registrations. If you submit a purchase order, you will receive an invoice, which must be returned with payment. All conference/seminar payments must be made prior to the event start date. IIE does not accept purchase orders for dues or subscription payments. These transactions require payment in full by check, VISA, MasterCard, or American Express to initiate the process. If payment is not received, a proforma invoice will be sent and the transaction will be suspended until the payment is received.
