Billing contact
The Billing Contact is the person or organization that will be demanded for registrations and renewals of the domain name and responsible for ensuring payment of those invoices. This is the person who is responsible for initial and recurring billing for the Domain Name. The billing contact may give you your payment details associated with your account. The billing contact does not have to work for the organisation in whose name a certificate is being requested, but should work for the organisation to whom the invoice should be addressed. The billing contact should be in a position to ensure prompt payment of fees.
