E-invoicing in Austria

Austria has a clear federal B2G e-invoicing mandate but no general B2B e-invoicing mandate. Suppliers to Austrian federal government departments must submit structured e-invoices, while private-sector e-invoicing remains voluntary unless required contractually.

The Austrian model is practical and well-established: businesses use the federal e-invoicing portal, the Unternehmensserviceportal (USP), Peppol or approved technical channels, with ebInterface and UBL-based formats playing a central role.

What the mandate means

Suppliers to Austrian federal government departments must issue structured e-invoices. Paper invoices and ordinary PDFs are not sufficient for covered federal B2G transactions. Sub-central public authorities may use similar processes, but the legal mandate is strongest at federal level.
For B2B, e-invoicing is voluntary. Many businesses still adopt it for process automation, but there is no nationwide domestic B2B mandate today.

What businesses should do now

Businesses selling to Austrian federal entities should validate whether their invoice format and transmission route are accepted.

Foreign suppliers should consider Peppol access, while Austrian suppliers often use USP or e-Rechnung.gv.at.

B2B businesses should prepare for future EU developments by ensuring EN 16931-compatible invoice data is available in the ERP.
