When does the mandate apply?
Germany is rolling out the mandate in stages — three deadlines determine when it applies to you.
1 Jan 2025
Since 2025: receiving
Every business must be able to receive e-invoices. This is already in effect.
1 Jan 2027
From 2027: issuing
Businesses with more than €800,000 in annual revenue must issue e-invoices.
1 Jan 2028
From 2028
The issuing obligation then applies to all B2B businesses.
Austria has no B2B mandate. Companies invoicing federal authorities have been doing it electronically since 2014 — via ebInterface or PEPPOL.
Many formats — the right tool for each.
Analyze
Detects the format and validates required fields and totals against EN 16931 — for Factur-X, ZUGFeRD, PEPPOL BIS 3.0, ebInterface and XRechnung.
Validate
Checks your invoice against the official rule sets — the same validation used in professional settings. You'll see whether it's fully compliant.
Create
Enter your invoice data and get back an EN-16931-compliant invoice — as Factur-X, ZUGFeRD, PEPPOL BIS 3.0, ebInterface or XRechnung.
The key formats
milchrechnung works with the formats used in Germany and Austria: Factur-X and ZUGFeRD, XRechnung, PEPPOL BIS 3.0 and ebInterface. All are built on EN 16931 — the shared European model.
