What happened?

A-Trust has unexpectedly cancelled the SEE for some customers. Without a valid SEE, you can no longer use the orderbird app in compliance with the RKSV regulations. We sent detailed information about this in our emails from July 2018.

Am I affected?

You are likely affected if: 

  • you receive the error message “Signaturerstellungseinheit ausgefallen” when trying to sign an invoice and
  • you received emails from orderbird in July 2018 regarding “Neue SEE einrichten”. 

How do I set up the new SEE?

Follow the step-by-step instructions in the links below to set up your new SEE:
