If business billing information
If an order / PO number is required, but it is not known yet, please note that it is not yet known.
If the invoice can also be sent by mail, please fill in the e-mail address.
Should there be additional requirements for invoicing? send it to an email at: firstname.lastname@example.org by name and course.
I am aware that naming a business invoice address does not free the student from his obligation for the course to be paid.
