What Is E-Invoicing? A Plain-Language Explanation

If you've heard that Germany is making e-invoicing mandatory and you're wondering what exactly that means — this article is for you.

The Short Answer

An e-invoice (elektronische Rechnung) is an invoice that is:

1. Created in a structured digital format (XML)
2. Transmitted electronically
3. Can be automatically processed by software — no human reading required

A PDF is NOT an e-invoice. This is the most common misconception. A PDF is just a picture of an invoice. A computer can display it, but it can't automatically extract the line items, tax amounts, or payment details without OCR (which is error-prone).

Why Does It Matter?

The German government is making structured e-invoicing mandatory for all B2B transactions starting in 2025. The goal is to:

• Reduce VAT fraud (estimated €11 billion gap in Germany)
• Improve efficiency (no more manual data entry)
• Align with EU standards (the whole EU is moving this direction)

What Formats Qualify?

Under the new German law, e-invoices must comply with the European standard EN 16931. In practice, this means:

XRechnung

• Pure XML file
• The German national standard
• Looks like code to humans — designed for machines
• Mandatory for government invoices since 2020

ZUGFeRD 2.x

• A PDF that also contains embedded XML data
• Best of both worlds: humans see a normal invoice, machines read the data
• Must use Profile "EN 16931" or "XRechnung" to be compliant

Peppol BIS Billing 3.0

• Sent through the Peppol network (like a secure postal system for invoices)
• Used heavily in Scandinavia, growing in Germany
• Requires a Peppol Access Point provider

What Does NOT Qualify?

• ❌ Paper invoices
• ❌ Simple PDF files (even if emailed)
• ❌ Scanned invoices
• ❌ Word or Excel documents
• ❌ ZUGFeRD "Minimum" or "Basic" profiles (not EN 16931 compliant)

What Do I Need to Do?

By January 2025: Make sure you can receive e-invoices. At minimum, this means having an email address that accepts XML attachments and software that can read them.

By 2027/2028: You'll also need to send e-invoices. This requires accounting software that can generate XRechnung or ZUGFeRD 2.x files.
