We support electronic invoicing via the Peppol network.
You can indicate this during registration by checking the "e-invoicing" box. If you are already registered, you can also enable it later by going to your profile; then click on Organization and change your organization.
For e-invoicing, you will need the OIN (organization identification number) of your organization or institution. In addition, a test phase may be required. Please have your administration contact us regarding this.
