The ZRE and OZG-RE invoice submission platforms have accepted the current standard and the XRechnung extension since 1 January 2021, so if the XRechnung extension is relevant for you, it is possible to use it on those platforms. However, before using the XRechnung extension, the invoice issuer and the invoice recipient should communicate with each other to avoid any difficulties with formats to be used.
If you create invoices using the web submission form on the invoice submission platforms, under the tab “Invoice lines” you can select the button “Add sub invoice line” to add more sub invoice lines, as shown in figures 2 and 3 below. Under the tab “Attachments” you can embed XML files in the invoice as supporting documents. In this way, you can create an XRechnung extension.
If you submit invoices using the web upload function on the invoice submission platforms, you can submit completed e-invoices compliant with the XRechnung extension using the upload function. If you have further questions about creating e-invoices, please contact your software provider.
If you submit invoices using De-Mail, email or Peppol, you can submit completed e-invoices compliant with the XRechnung extension using those transmission methods as well. If you have further questions about creating e-invoices, please contact your software provider.
