Last updated on Aug 04, 2025

To adjust your invoice, we need a written request from you in any case.

Therefore, please send us your change requests via e-mail or by using our ticket system:

Please make sure to provide us with your order or invoice number and clearly describe your request for changes. We will then send you the corrected invoice as soon as possible.

Please note that it may be necessary to return the original invoice under certain circumstances.
