Complete online registration forms for all individuals covered by a single purchase order using one SXSWedu Shopping Cart. Follow these step by step instructions to purchase a SXSWedu registration by PO from your shopping cart. Click the appropriate button indicating that the registration(s) will be paid by PO and enter the necessary information for SXSWedu to generate an invoice. After the PO has been issued you must return to that Shopping Cart and enter the PO number. The PO MUST be applied prior to the registration deadline or new rates will apply. At that point those registrations will be considered paid and confirmed, and the registrants can request a hotel room.
