Can I change the billing address afterwards?

The invoicing of entry fees is automated at the end of the month based on the stored customer data. A subsequent change to the invoice is not possible once it has been issued; once the invoice is generated, it cannot be altered.

If no alternate billing address is provided, the invoice will automatically be issued to the address stored in the customer account.

Can I specify a different billing address?

You can specify an alternate customer number as the billing address in the general payment settings of your registration forms. 

The owner of the event undertakes to inform the customer with the alternate customer number of all rights and obligations arising from the contract and ensures their complete compliance.
