The payment options are payment by credit card (Visa, Mastercard, Google Pay) or against invoice (cheques will not be accepted). You will receive a receipt once the payment is processed.
If you are paying by credit card, you do not have to fill in the invoicing address unless you need the information to appear on the receipt.
If you're a keynote speaker you do not need to fill in invoicing information. However, please note that keynote speakers still need to pay for excursion attendance. Therefore, if you are a keynote speaker and wish to join an excursion, please complete the invoicing information and proceed to payment.
If you wish to pay against invoice, kindly fill in the invoicing address fields and your invoice reference (if needed). The invoice will be sent to your e-mail as a PDF document and EUR 20 invoicing fee will be added to the invoice. Note that an additional fee of EUR 20 will be charged for any changes to a sent invoice (e.g. invalid invoicing address or needed data not given below).
Finnish participants can request an e-invoice (verkkolasku) by giving their e-invoicing information (OVT, VAT reg/y-tunnus, operator) in the invoicing address fields.
