E-invoicing
According to section 4 (3) of the E-Invoicing Ordinance (E-Rechnungsverordnung, ERechV), every invoice submission portal of the federal administration must be made available via the central federal administrative portal as referred to in section 2 (2) of the Online Access Act (Onlinezugangsgesetz, OZG). The website www.verwaltung.bund.de is a portal of the federal administration as referred to in section 2 (2) of the Online Access Act. This website offers links to the Federal Central Invoice Submission Portal (ZRE) and to the invoice submission portal which complies with the Online Access Act (OZG-RE). It also provides links to other invoice submission platforms for institutions which are not allowed to connect to the ZRE or the OZG-RE but are required by the E-Invoicing Ordinance to accept electronic invoices. Invoice issuers can access the ZRE and the OZG-RE via the federal portal. This portal does not require registration, but invoice issuers must create a user account to use the ZRE and the OZG-RE, as stipulated in the portals’ terms of use.
To find the ZRE and OZG-RE on the federal portal, enter “ZRE” in the search field of www.verwaltung.bund.de. You will then be taken to the page “Transmit invoices electronically via e‑invoice platforms”. Click on the text or on the word “More”. On the new page, click on “Forms & Online Services”. Under “Related Links”, you will find links to the ZRE and OZG-RE and any other available invoice submission platforms.
When creating an electronic invoice (e-invoice), the invoice issuer has the option to give the invoice recipient a discount (reduced price) for early payment within a specified period of time.
Example: Payment is due within 30 days. For payment received within 10 days (discount period), a 2% discount is given on the invoice amount due.
Directions for including information about discounts for each transmission method:
Web submission:
Here you will find detailed instructions for including information about discounts when using the web submission form for the ZRE and OZG-RE.

Email/De-Mail:
If you use email or De-Mail to transmit your invoice, your completed e-invoice (XML file) must meet the same requirements for information about discounts as described in the paragraph on using the upload method (see “Upload”).
Peppol:
If you use Peppol to transmit your invoice, your completed e-invoice (XML file) must meet the same requirements for information about discounts as described in the paragraph on using the upload transmission method (see “Upload”).
When creating an electronic invoice (e-invoice), the invoice issuer has the option to charge interest if the invoice recipient does not pay the invoice within the allotted time.
Interest may then be charged if payment is not made by the calendar date given on the invoice, or if the invoice is not paid in full within 30 days of the payment due date and receipt of the invoice. The delay is counted from the first day after the due date and ends on the day payment is received. Interest is to be charged for each day of the delay.
Example: For example, you may specify the following terms of payment: Payment is due within 30 days. Payment that is 10 days late will be subject to interest of 5% on the amount due.

The federal E-Invoicing Ordinance governs the sending of e-invoices by suppliers to the federal administration. The basis for e-invoicing in Germany’s federal states, on the other hand, is EU Directive 2014/55/EU, which the federal states are responsible for implementing themselves.
In order to help you send e-invoices to the federal states, we have put together some useful information:
E-invoices must be created using a data format that meets the requirements of
- the European standard (EN 16931),
- the terms of use for the relevant invoice submission portal,
- and the requirements of the federal E-Invoicing Ordinance (E-Rechnungsverordnung, ERechV).
In general, invoices for the federal administration must be issued using the currently valid XRechnung standard. Other invoice formats may be used (such as ZUGFeRD version 2.1.1 or later in the XRECHNUNG profile, as a simple structured XML file) as long as they meet the above-mentioned requirements.
Depending on the ERP you use, it may be possible to create an e-invoice in the outgoing invoice system. If you are not sure, contact the manufacturer and ask whether the ERP supports electronic invoicing in XRechnung standard.
An e-invoice can be rejected by the invoice submission portal because it does not meet formal requirements or contains calculation errors, or it can be rejected by the invoice recipient due to errors of fact or content.
What to do in case of formal errors in an invoice:
If you use the transmission method “web submission” (manual invoice creation via the portal) or “upload” (manual upload of existing e-invoices to the portal), you can have your e-invoice validated directly by the portal. An error report stating the formal errors in the invoice will be displayed to you before the invoice is sent.
If you are using a different transmission method and your e-invoice has been rejected by the portal, on both portals you will see a magnifying glass symbol in the overview of invoices. If you click on this symbol, you will find detailed results of the formal checks carried out on the e-invoice in question.
You can then create a new invoice, correcting the identified errors before you submit it.
What to do in case of errors of fact or content in an invoice:
If your e-invoice is rejected by the recipient, this is probably due to an error that the recipient has identified regarding the calculation or factual content of the invoice.
When rejecting an e-invoice, the invoice recipient has the option of leaving a comment for you about the reason for the rejection.
If no reason is stated, please check your submitted e-invoice carefully and contact the invoice recipient if necessary.
You can then re-submit the corrected e-invoice.
According toSection 5 of the Federal Government’s Regulation on Electronic Invoicing , in addition to VAT invoicing elements (for more on this, see Section 14 of the Value-Added Tax Act [UStG]), an e-invoice must contain the following information at a minimum:
- Buyer reference – you will be given the buyer reference when the contract is awarded.
- Terms of payment (payment due date or text description of the terms)
- The payment recipient’s bank details
- The invoice issuer’s postal or De-Mail address
| Mandatory information according to Section 5 E-RechV of the Federal Government | To be entered in the following elements of an XRechnung invoice (cf. XRechnung V.1.1) |
|---|---|
| Buyer reference | BT-10 BT = Business term or information item |
| Bank details | For Bank transfer: BG-17 (BT-84 to 86) For direct debit: BG-19 (BT-89 to91) BG = Business group or group of information items |
| Terms of payment | BT-9 or BT-20 |
| Email or De-Mail address | BT-43 |
| Supplier number* | BT-29 |
| Purchase order number* | BT-13 |
*Mandatory information, if transmitted at the time of commissioning
A specific data field is provided for each of these additional details. Further information on the XRechnung invoice standard can be found in the FAQ section on XRechnung invoicing.
No! A special program is not required. There are several options for creating an electronic invoice to authorities of the Federal Administration, in particular:
- Use of an (ERP) system or service provider
Do you use a service provider or commercially available software for invoicing? Contact the manufacturer and find out whether electronic invoicing is supported. Do you use your own system? Clarify with your IT department which steps are necessary to create e-invoices that are compliant with the EU standard. - Use of the ZRE/OZG-RE web-based entry system
If you are not using an outgoing invoice system or if you need an interim solution, familiarise yourself with the ZRE/OZG-RE web-based entry system. On both platforms, the Federal Government provides functions for manual entry of invoices. Templates can also be created and downloaded for later use or reuse.
The following federal invoice receipt platforms must be used for submitting e-invoices.
- Direct Federal Administration institutions and federal constitutional bodies are connected to the ZRE.
- Invoices to bodies of the indirect Federal Administration (and to cooperating federal states) are submitted via the OZG-RE platform.
Note: Indirect Federal Administration public contracting authorities are not obliged to use the OZG-RE, which is why in-house solutions are also possible in individual cases in addition to OZG-RE. The contracting authority will inform its invoice issuers about the invoice submission method to be used.
You can obtain more detailed information (for example, which platform is available to you) via the underlying order or, of course, directly from the invoice recipient.
In addition, we offer an overview of the contracting authorities connected to the two platforms on the website (section ‘Invoice issuers – General information on e-invoices’). It does not replace bilateral communication with your ordering party to provide further information such as buyer references.
The two central platforms require prior registration and activation of the desired transmission channels for the transmission of the invoice. For high invoice volumes, the mass transmission channels web service via Peppol, email and, in the future, De-Mail are suitable. Alternatively, the upload and web entry functions are also available. Make sure you identify the transmission channel that suits you best.

No. As defined in EU Directive 2014/55/EU, e-invoicing is a structured data set. A PDF file is not an e-invoice under these requirements.
The latest version of the XRechnung standard must always be used when issuing e-invoices. Another standard (e.g. ZUGFeRD 2.1.1 XRechnung profile without PDF visual format, as a purely structured XML file) can also be used if it complies with the requirements of the European standard for electronic invoicing (EN-16931), the Federal Government’s Regulation on Electronic Invoicing (E-RechV) and the Federal Government’s terms of use for the invoice submission platforms.
Invoice formats that do not comply with the requirements of the European standard cannot be taken into account.
Invoice supporting documents or attachments must be embedded in the invoice data record and may not be sent separately as an attachment to an email or De-Mail.
The maximum permissible size of an invoice depends on the transmission channel selected (e.g. for ZRE: 10 MB for email attachments or 11 MB for attachments in the web entry). Please refer to the terms of use of the platform. The maximum number of embedded documents supporting the invoice is limited to 200. Permitted file types of the embedded documents are: ‘png’, ‘pdf’, ‘jpg’, ‘jpeg’, ‘xlsx’, ‘ods’ and ‘csv’.“. Attachments may not contain active content (e.g. macros). Changes to these restrictions will be announced via the invoice receipt platforms.
Invoice documents with attachments that require paper-based submission under other legal provisions (export certificates, customs documents, etc.) remain unaffected by the above regulations.
More detailed information on the XRechnung standard can be found at KoSIT.
In principle, the obligation for contractors to invoice the Federal Government electronically applies from 27/11/2020. The exceptions are regulated in the ordinance and are described as follows:
- Invoices issued after the fulfilment of a direct order up to an amount of 1,000 euros (order value)
- Invoices subject to the exceptions under Section 8 or Section 9 (confidential invoice data as well as matters of the European External Action Service and other procurements abroad)
- Invoices to be issued in procedures for the borrowed administration arrangement under Section 159(1)(5) of the Act against Restraints of Competition (GWB).
- Irrespective of the legal obligation, an obligation to submit e-invoices may also arise from the respective underlying order or contractual relationship.
An e-invoice is invoice information that is transmitted electronically and automatically received and processed. An e-invoice facilitates consistent, automated transmission and processing of invoice information from the invoice submission to payment.
An e-invoice provides invoice content in a structured, machine-readable data set instead of on paper or in an image file such as a PDF. This ensures that information provided in this form by the invoice issuer can be:
a) transmitted electronically
b) received electronically
c) as well as processed and approved for payment automatically and seamlessly.
