nic.at offers a 3% discount on future domain invoices for payment via automatic debit transfer. The key date is the date on which nic.at receives the direct debit authorisation. nic.at also provides a 3% discount to e-mail incoices (see also the FAQ "How do I receive my billing documents?"). Further special conditions are applicable for combined invoice recipients who have more than 50 domains and for nic.at registrars. Outstanding accounts are collected at maturity.

Domains are charged annually – but according to the service period of the relevant domain rather than along with the calendar year. The service period begins at the day of the domain delegation and lasts for one year.

The fees are to be paid in advance. The invoice for the registration of a domain will be dispatched after about five working days. The following annual fees are due to be paid within 45 days after billing. The invoice can be cancelled if the domain cancellation has been submitted in due time (28 days before the beginning of a new service period).
