E-invoicing in Austria: Complete Guide

E-invoicing Framework in Austria

Austria was one of the earlier adopters of electronic invoicing in the public sector in Europe. While the country does not currently impose a mandatory e-invoicing regime for business-to-business (B2B) transactions, electronic invoicing is required for suppliers invoicing federal public authorities.

For businesses operating in Austria or supplying the Austrian public sector, understanding the current framework is important to ensure compliance and streamline invoicing processes.

This article explains the current e-invoicing rules in Austria, the formats and platforms used, and what businesses should consider when sending electronic invoices.

Mandatory B2G E-Invoicing in Austria

Electronic invoicing to Austrian federal public authorities is mandatory. Suppliers providing goods or services to the federal government must submit invoices in structured electronic format. This requirement applies to both domestic and foreign suppliers. In the case of foreign non-established companies, these are obliged to issue e-invoices to the extent technically possible.

The obligation is based on the Austrian ICT Consolidation Act and public procurement legislation implementing the EU Directive on electronic invoicing in public procurement. B2G scope:

• Since April 2020, all suppliers to federal public entities must issue e-invoices rather than paper invoices. The requirement applies when invoicing central government bodies such as ministries and other federal institutions.
• Sub-central authorities, such as regional and municipal administrations, are not legally required to receive e-invoices but may voluntarily adopt the same infrastructure.

What are the Platforms Used for B2G E-Invoicing in Austria?

Austria provides a central government platform for the submission of electronic invoices.

The primary platform used by the federal government is e-Rechnung.gv.at, which serves as the official electronic invoicing portal. Suppliers can submit invoices through this platform using several methods, including:

• Manual submission through a web form
• File upload
• Automated submission via web services

Access to the portal typically requires authentication through the Unternehmensserviceportal (USP), the Austrian Business Service Portal.

Electronic invoices may also be transmitted to e-Rechnung.gv.at via the Peppol network, which provides a standardised infrastructure for the secure exchange of electronic documents between businesses and public authorities. Learn more.

Peppol is commonly used by international suppliers and organisations that operate across multiple jurisdictions, as it enables interoperability with many public sector e-invoicing systems in Europe. All Austrian federal public administrations are reachable through the Peppol network, making it a practical option for cross-border invoicing.

What Are the Accepted Invoice Formats for B2G E-invoicing in Austria?

Electronic invoices submitted to Austrian public authorities must comply with structured formats aligned with the European standard EN 16931. The most commonly accepted formats include:

• ebInterface – the Austrian national XML e-invoicing standard
• Peppol BIS Billing 3.0 – the Peppol standard widely used for cross-border e-invoicing

Both formats allow invoices to be processed automatically by government systems and ensure compliance with EU interoperability standards.

B2B E-Invoicing in Austria

Unlike several other EU Member States, Austria does not currently impose a mandatory B2B e-invoicing regime.

Businesses may still exchange electronic invoices if both parties agree to do so. Common methods include:

• Electronic Data Interchange (EDI)
• Structured e-invoices using Peppol
• PDF invoices with appropriate audit controls.

Although not mandatory, many companies have voluntarily adopted electronic invoicing in order to improve efficiency, automate accounting processes, and reduce administrative costs.

How Businesses Can Send Peppol E-Invoices in Austria

Businesses wishing to transmit electronic invoices through the Peppol network typically do so via a Peppol Access Point provider.

Using a certified provider allows companies to connect to the Peppol network without developing their own infrastructure and ensures that invoices are transmitted in the required structured formats.

Providers such as Marosa support the transmission of Peppol e-invoices in Austria, enabling businesses to exchange compliant electronic invoices with Austrian public authorities and trading partners.

Austria’s e-invoicing framework currently focuses on public sector transactions, where e-invoices are mandatory for suppliers to the federal government. Businesses can submit invoices through the official e-Rechnung.gv.at portal or via the Peppol network using recognised formats such as ebInterface or Peppol BIS. While B2B e-invoicing remains voluntary, many companies are already adopting structured electronic invoicing to streamline operations and prepare for broader digital reporting developments across the EU.
