The Peppol network was developed by the OpenPeppol non-profit organisation with the aim of enabling smooth, standardised and automated cross-border e-procurement. This includes the transmission of electronic invoices.
The improved efficiency resulting from electronic invoice processing can help increase the liquidity of suppliers.
Germany’s federal administration uses one federal submission portal for e-invoices: The OZG-RE (Online Access Act-compliant Invoice Submission Portal) to which all institutions of the direct federal administration are connected, and which is also offered to organisations of the indirect federal administration and cooperating federal states. Instead of using the OZG-RE, organisations of the indirect federal administration may also implement their own solutions for receiving e-invoices provided they are compliant with the Ordinance on Electronic Invoicing in Federal Public Procurement (E-RechV) (not accessible) [PDF, 46 KB] .
There are four options available to invoice issuers for transmitting e-invoices to customers who are connected to the federal invoice submission portal OZG-RE:
Unlike the other options, Peppol is the only transmission method which supports automated machine-to-machine (m2m) communication and the mass export of e-invoices.
If you choose to submit your invoices via Peppol, you have two different options:
A verified Peppol service provider makes a web service available to you. At Peppol.org, you will find a list of Peppol service providers that you can ask for a quote.
Peppol enables the fully automated exchange of electronic documents. This means that all participants can seamlessly export and import documents from different processing systems. The Peppol network is designed to transmit high volumes of e-invoices.
Automated invoicing involves additional benefits for suppliers:
For invoicing clerks, transmission via Peppol is the most convenient e-invoicing option because Peppol is directly connected to their ERP system via an interface. Once the technical connection is in place, invoices can be submitted with just a few mouse clicks in your own ERP system.
Peppol enables you to process e-invoices seamlessly (machine-to-machine) and conveniently, without having to switch between different systems. Also, you can dispatch large volumes of e-invoices (mass exports).
Using Peppol to transmit your documents helps to reduce operating errors and increases transparency across the entire invoicing process.
Peppol ensures the highest security standards and compliance with data protection regulations when it comes to the transmission of documents.
Introducing uniform and mandatory standards for all participants in the Peppol network significantly facilitates the exchange of documents from different systems.
Peppol requires all participants to apply specific standards for the electronic exchange of documents, which are known as Business Interoperability Specifications (BIS).
In general, e-invoices addressed to the federal administration must be issued using the currently valid version of the XRechnung standard. Other standards 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 requirements of the European e-invoicing standard (EN 16931), the terms of use for the federal invoice submission portal and the requirements of the Ordinance on Electronic Invoicing in Federal Public Procurement (ERechV). Your ERP system must be able to generate electronic invoices according to these requirements. The Xrechnung standard is operated and maintained by KoSIT (Coordination Office for IT Standards), which also provides a validation tool (KoSIT validator) to check that e-invoices are formally correct. You may use this tool to check your e-invoices before sending them to ensure they are not rejected by the OZG-RE federal invoice submission portal. More information is available here: KoSIT (German only)
Using Peppol is particularly easy if your ERP system is able to use Peppol directly via an interface. To implement such a solution, it may be advisable to contact a Peppol service provider, who will also take care of your registration in the Peppol network if necessary so that you can use your personal Peppol sender ID.
Alternatively, you can set up your own infrastructure for using Peppol. More information is available here: FAQs regarding Peppol
In the Peppol network, the Peppol participant identifier serves to clearly identify a given participant; its function is similar to that of a VAT ID or an IBAN in online banking.
A distinction is made between the sender ID (invoice issuer) and the receiver ID (invoice recipient).
In order to transmit an e-invoice via Peppol, you will need the unique Peppol-Receiver-ID of the invoice recipient for addressing purposes. In the federal administration, the Peppol receiver ID is generally composed of the prefix 0204 and the buyer reference ( Leitweg-ID) of your customer. You will find the buyer reference in the contract documents; otherwise you can obtain it from your customer upon request.
The structure of the Peppol participant ID is shown in the list below.
Note: When sending e-invoices via Peppol, please address them in the BIS document (Business Interoperability Specification). The BIS document establishes a clearly defined standard for exchanging documents within the network. Here, you have to enter the invoice recipient’s Peppol receiver ID. In the e-invoice itself, however, you have to enter the buyer reference, otherwise the e-invoice will be rejected by the OZG-RE portal.
In order to submit your e-invoices to the federal administration, you currently need to be registered – in accordance with the relevant terms of use – with the federal invoice submission portal; this applies regardless of the transmission method you choose.
Registration with and use of the OZG-RE submission portal is free of charge. You can either see from the buyer reference that the OZG-RE platform is being addressed, or you can request this information from your customer.
Alternatively, we also offer an overview of the organisations connected to OZG-RE, respectively. Since listing is voluntary, some organisations may be missing from the list.
