The annual fee for .dk domains is collected in the first year by One.com and then in following years by DK Hostmaster A/S. The hosting is always collected by one.com. This means you will receive two invoices after the first year.
One.com charges all other annual domain fees via the yearly invoice, which is sent out around 60 days before a subscription period ending.
