Please pay by card rather than invoice if you can. Due to the cost of processing invoices, we strongly prefer delegates to pay by credit card. If you are unable to pay by credit card, please proceed with the booking and on the final stage of booking there will be an additional button ‘pay by invoice’ as well as the usual button to 'pay online', please then enter a purchase order number. Our accounts team will be notified of your invoice request and will supply you with an invoice to pay. If you do not provide an official PO number, we will not be able to process and confirm your booking. All invoices must be paid in full before you can attend the event
