The ZRE and the OZG-RE are functionally similar for invoice issuers and for invoice recipients. However, the group of affiliated invoice recipients is different.
The ZRE is the mandatory central invoice receipt platform for the institutions of the direct Federal Administration. The OZG-RE, on the other hand, is an optional service offered by the Federal Government; it forwards invoices to affiliated institutions of the indirect Federal Administration, affiliated beneficiaries and cooperating federal states.
A support service is available to answer your questions about using the OZG-RE or if you are having issues.
It can be reached by email or by telephone:
Support and service for invoice recipients (authorised users):
(Mon – Fri 07:00 AM – 06:00 PM)
Support and service for invoice recipients:
(Mon – Fri 08:00 AM – 04:00 PM)
If your company is already registered for the OZG-RE, please contact the responsible administrator. The responsible administrator can add more users to the company account.
Yes! In order to be able to transmit invoices via OZG-RE, it is necessary to set up a company account.
Both registration and use of OZG-RE are free of charge for invoice issuers.
Please note that costs may be incurred by the user while using the OZG-RE platform, in particular for the provision, connection and operation of necessary software and hardware as well as for Internet use, which will not be reimbursed by the responsible parties (publisher and technical service provider) of the OZG-RE.
For each invoice provided via the OZG-RE, the invoice recipient must cover the cost. The amount of this payment is specified in the administrative agreement to be signed.
To register a company account for the first time, at least the following data must be entered:
- Business name
- VAT identifier
- Tax registration number
- First name
- Last name
If your company is already registered for the OZG-RE and only a new user needs to be created by the administrator, the following information must be provided:
- First name
- Last name
The following federal invoice receipt platforms must be used to submit electronic invoices:
- You can submit invoices to direct Federal Administration institutions and Federal Government constitutional bodies via the ZRE.
- You can submit invoices to institutions associated with the indirect Federal Administration, affiliated beneficiaries and cooperating federal states via the OZG-RE.
You will receive information on which invoice receipt platform to use via the underlying order or directly from the invoice recipient.
The OZG-RE assumes the following three tasks for the transmission of e-invoices:
- The receipt of e-invoices via various transmission channels.
- The technical verification of e-invoices (including invoice size, number and type of attachments, virus check, entry of all mandatory information)
- The transmission of e-invoices to the respective invoice recipient via buyer reference.
To ensure that an e-invoice can be forwarded by the ZRE to the intended invoice recipient, it is mandatory for the invoice issuer to provide a so-called buyer reference to uniquely identify the invoice recipient.
A user account can only be deleted by an administrator in your company. See your administrator for help with this.
The administrator is also able to delete the company account.
The email address can only be changed by the appropriate administrator (in the user management section). Contact your administrator.
When using the platforms, there are five submission channels available to invoice senders for invoices:
- Web-based data entry (available)
- Uploading (available)
- Email (available)
- De-Mail (coming soon)
- Web service via Peppol (available)
Yes, you can attach accompanying attachments to an electronic invoice.
Please note the following size and format specifications:
- Web-based data entry: Number of accompanying documents 200, maximum size of all attachments 15 MB
- Upload: Number of accompanying documents 200, maximum size of e-invoice, incl. attachments 15 MB
- Email: Number of accompanying documents 200, maximum size of e-invoice, incl. attachments 15 MB
- Web service via Peppol: Number of accompanying documents 200, maximum size of e-invoice, incl. attachments 15 MB
Permitted formats for accompanying attachments:
- PDF documents
- Images (PNG, JPEG)
- Text files (CSV)
- Excel spreadsheets (XLSX)
- Support and OpenDocument spreadsheets (ODS)
You can track the status of the submitted invoice. To do so, select “View status of submitted invoices” in the Home section.
Depending on the processing status, an invoice can have the following status types: new, delivered, received and rejected.
In this section, you can also continue with a manual invoice entry previously started via web-based data entry.
No. Invoices submitted via the OZG-RE cannot be recalled.
Users can track the current status of their invoice in the log view. If you have submitted an incorrect invoice by mistake, please contact the invoice recipient.
Yes, it is possible to save a local copy of sent invoices. A manual Download option is available in the “Processing status of submitted XRechnung invoices” section.
Note: The platform does not provide any audit-proof archive for invoice issuers. The generated e-invoice must be archived in XML format by the supplier or invoice issuer.
Which software can be used to open e-invoices in XML format once they have been created in the OZG-RE and saved locally?
If the company does not have software for viewing locally saved invoices in XML format, a solution can be purchased on the market or developed in house. No solutions can be recommended here.
There are no time restrictions on the creation or submission of invoices via the OZG-RE. Maintenance work may result in a short period of unavailability at times however. Upcoming maintenance work will be announced in advance via a pop-up window.
After logging in, navigate to “Personal Settings” via the person icon. You can change your password in this section.
You can reset your password using the “Forgot password?” function on the OZG-RE homepage by entering your email address. You will receive a link by email which you can use to specify a new password.
Indirect Federal Administration institutions (and cooperating states) are connected to the OZG-RE. See the following document for an overview of the public contracting authorities connected to the OZG-RE:
As an additional transmission channel, the OZG-RE provides the option of sending invoices from the originating software through a web service and transmission via the Peppol network. The submission of e-invoices via Peppol is essentially possible in three different ways:
- Use of the web service via the Federal Government’s Peppol (free).
- Use of an existing Peppol service provider (chargeable).
- Fee-based membership with OpenPEPPOL and the establishment of your own Peppol Access Point
In principle, no registration with the OZG-RE is needed to transmit electronic invoices via the Peppol web service. However, the processing status of invoices submitted via the Peppolweb service can only be viewed if the “Web-based data entry and Peppol” transmission channel is enabled after successful registration and if the PeppolSender ID used by the sender has been entered.
To send test invoices to the OZG-RE reference environment, please use the following IDs:
Peppol receiver ID = 0204:99661-WEBSERVICEOZG-28
Buyer reference = 99661-WEBSERVICEOZG-28
If you are already in contact with an invoice recipient, and you wish to test with them directly, you can also use their buyer reference.
Once transmission to the OZG-RE reference environment via Peppol is working, you may also send productive invoices. Please note that you also need to enter your Peppol Sender ID in User Administration in your account in the OZG-RE productive environment. The following should be noted for sending invoices via the ZRE productive environment:
Peppol receiver ID = 0204:Leitweg-ID Ihres Kunden
Buyer reference = teilt Ihnen Ihr Kunde mit.
