E-Invoicing in Austria
Austria was an early B2G adopter (mandatory since 2014) with its own ebInterface national standard alongside Peppol. B2B e-invoicing is voluntary but widely adopted. A mandatory B2B mandate is expected under EU ViDA, likely between 2027 and 2028.
Mandate Status
| Phase | Status | Scope |
|---|---|---|
| B2G | Live (Jan 2014) | All federal government suppliers |
| B2B mandate | 2027-2028 | Expected under ViDA |

Implementation Notes
ebInterface vs Peppol. Austria accepts both ebInterface 6.0 (national standard) and Peppol BIS Billing 3.0 for B2G. The ebInterface format is EN 16931 aligned but has Austrian-specific extensions. If you're building for multiple markets, Peppol BIS 3.0 is the safer choice. B2G invoices are submitted via the USP (Unternehmensserviceportal). Digital signatures are optional but recommended.
