Austria B2G E-Invoicing: Complete Guide for Government Suppliers — ebInterface and Peppol

Austria mandated electronic invoicing for central government suppliers on 1 January 2014 — over a decade ago and nearly eight years before Germany's B2G mandate. If you supply goods or services to the Austrian federal government (Bundesbehörden), or are considering doing so, this guide explains the current requirements.

Unlike Germany (XRechnung only) or Italy (FatturaPA only), Austria accepts two distinct formats for government invoices:

ebInterface is Austria's domestic e-invoicing standard, developed and maintained by the Wirtschaftskammer Österreich (WKO) — Austria's Federal Economic Chamber. The current version is ebInterface 6.0 (released 2022).

ebInterface is a purely Austrian format. It is not interoperable with other EU countries' e-invoicing systems without conversion. However, it is deeply integrated with Austrian accounting software (BMD, RZL, Sage Österreich) and is supported by all major Austrian invoicing platforms.

Since 2018, the Austrian government also accepts Peppol BIS 3.0 invoices for all federal government contracts. The Austrian Peppol authority is the Bundesrechenzentrum (BRZ) — the federal computing centre.

Austrian Peppol ID format: 9915:XXXXXXXXXXX (9915 is the Austrian Peppol scheme code for Steuernummer, followed by the Steuernummer)

The primary Austrian federal government e-invoicing portal is e-Rechnung.at, operated by the Bundesrechenzentrum (BRZ). This is the equivalent of Germany's OZG-RE (Online Zugangsgesetz-Rechnungseingang) or Italy's SDI.

How to submit: 1. Register as a supplier at the portal (requires FinanzOnline credentials) 2. Generate the invoice in ebInterface 6.0 or Peppol BIS 3.0 format 3. Submit directly via the portal (web upload) or via Peppol network 4. Receive an acknowledgement receipt (Eingangsbestätigung)

The portal also supports EDIAKT II — Austria's legacy EDI standard for large enterprise government suppliers with pre-existing EDI connections. New implementations should use ebInterface or Peppol.

Länder (states) and municipalities: Austria's nine states and municipalities operate their own procurement systems. Several Länder (including Vienna, Lower Austria, and Upper Austria) have adopted their own electronic invoicing requirements — typically also based on ebInterface or Peppol. Check directly with the relevant Landes- or Gemeindebehörde for their specific requirements.

1. Get a FinanzOnline account (if you don't already have one) — required for portal registration
2. Check whether you need ebInterface or Peppol: If you already have Peppol from Belgian or German B2G work, use Peppol. If you are Austria-only, ebInterface 6.0 is simpler.
3. Register at e-rechnung.gv.at with your UID-Nummer (Austrian VAT number)
4. Configure your accounting software: BMD, RZL, SAGE Österreich, and Buchhaltungsprogramme.at all support ebInterface export natively. For Peppol, you need a certified Peppol access point.
5. Reference the Auftragsnummer (order number) or EKID (procurement ID) on every invoice — Austrian government agencies will reject invoices that do not reference the correct procurement ID.

Austria currently has no B2B e-invoicing mandate — only B2G. However, the EU's ViDA directive (formally adopted May 2026) requires all EU member states to implement B2B digital reporting requirements by 1 January 2028 (for cross-border transactions) and gives member states flexibility on domestic B2B timing.

Austria's government (BMF) has indicated it will align with ViDA through a Peppol-based approach for B2B, mirroring Belgium and the Netherlands. A formal proposal is expected in Q3 2026.

Practical implication: If you set up Peppol for Austrian B2G now, you will be positioned for eventual Austrian B2B requirements without additional infrastructure changes.
