You can do this manually via My Viking, or using an automatic payment method

It's not possible to receive a paper credit transfer with your paper invoice. To configure your direct debit, choose your automatic payment when selecting your subscription. If you prefer paying by bank transfer, keep in mind that it can take a few working days for your payment to be processed in our systems. In case you want to dispute your invoice/payment invitation, please mail the following information to the number of your invoice/payment invitation and which costs exactly you dispute. Our helpdesk will take it from there.
