E-Invoicing in the Automotive Trade: An End to PDF Chaos

Since January 1, 2025, new e-invoicing rules have applied to transactions between domestic businesses in Germany. The obligation to be able to receive e-invoices has applied since that date; the obligation to issue them is being phased in and is subject to statutory exceptions. But confusion remains in the automotive trade: Is my PDF still sufficient? Do I need new software? What should I do if a supplier sends me an XML file?

The good news is that the situation is less dramatic than many advisors claim, provided you clearly distinguish incoming invoices (receipt) from outgoing invoices (issuance).

Reviewed and updated on July 14, 2026: This article reflects the current German Federal Ministry of Finance (BMF) FAQ on mandatory e-invoicing, updated in March 2026. Importantly, the obligation to be able to receive e-invoices has applied since January 1, 2025, including to businesses using Germany’s small-business VAT scheme. Transitional rules and statutory exceptions apply to issuance.

The GoBD provide the framework here: If you corrupt the original XML when storing it or only print it out, a tax audit can become expensive. The Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in elektronischer Form (German principles for proper digital accounting and record retention, GoBD) govern this area.

Quick Definition: What Is a “Real” E-Invoice?

An e-invoice contains invoice data in a structured data record (XML) that computers can process automatically.

• Standard PDF: Merely an “image” for the human eye, not an e-invoice.
• XRechnung: A pure XML data record that is difficult for people to read, and the standard used by public authorities.
• ZUGFeRD (PDF/A-3): The hybrid solution. It looks like a PDF, but contains the XML data within it. This is ideal for the automotive trade.

Receipt Obligation: Do I Have to Accept E-Invoices Immediately?

This is where the greatest misunderstanding arises. Many dealers think: “I still have transitional periods, so I do not need to do anything.” That is incorrect. The transitional periods apply only to issuing invoices.

For receipt, the following has applied since January 1, 2025: If a supplier, such as a parts dealer or energy provider, sends you a real e-invoice, such as an XRechnung, you may not reject it. Every domestic business must be able to receive it, including businesses using Germany’s small-business VAT scheme. An email inbox is generally sufficient for receipt. When retaining the invoice, the original structured component must remain intact.

Our Recommendation: Do Not Experiment, Use DATEV

At Autaxo, we deliberately do not offer our own incoming-invoice platform. Why? Because a market standard already exists and is better than any improvised solution: DATEV.

Instead of struggling with third-party tools, we recommend:

1. Speak with your tax advisor: Do they use DATEV Unternehmen online?
2. Use the DATEV e-invoicing platform: It is secure, GoBD-compliant, and connected directly to your accounting.
3. The workflow: Upload the e-invoice, or receive it by email, directly in the DATEV portal. It is visualized, checked, and posted there.

Tip: Dealers without a DATEV tax advisor can also use the DATEV e-invoicing platform independently. It is affordable and future-proof.

Issuance Obligation: When Do I Have to Issue E-Invoices?

If you sell vehicles to other domestic businesses (B2B), the obligation to issue an e-invoice may generally apply to you as well. The relevant factors are the date, your total prior-year revenue, and the statutory exceptions. All invoice issuers may use the transitional rule through the end of 2026. For issuers whose total prior-year revenue does not exceed €800,000, it is extended through the end of 2027.

The Autaxo Solution: ZUGFeRD (PDF/A-3)

Why wait? Autaxo already supports the PDF/A-3 format (ZUGFeRD).

The benefit: You create the invoice in Autaxo as usual. The result is one file that serves two purposes:

1. For the customer: It looks like a standard PDF that can be printed and read.
2. For the tax authority or software: The structured XML data record is attached within the file.

This meets the technical format requirements for an e-invoice when one is required for the transaction, without requiring your customers, or you, to fundamentally change the established process.

Important for the automotive trade: The invoice wording and tax case depend on the transaction, such as section 25a versus an intra-Community supply versus an export.

Timeline: Which Deadlines Apply to Dealers?

The following timeline based on the current BMF guidance shows when each requirement becomes binding:

Important issuance exceptions: Another type of invoice remains permissible for, among other cases, low-value invoices up to €250 gross, tickets treated as invoices, and supplies or services provided by businesses using Germany’s small-business VAT scheme under section 34a UStDV. Further exceptions follow from section 14 UStG and the BMF guidance.

Conclusion: You have had to address receipt since 2025, including if you use Germany’s small-business VAT scheme. Whether and when you must issue an e-invoice depends on the transitional period, total prior-year revenue, the type of transaction, and statutory exceptions. Autaxo and ZUGFeRD already provide the technical preparation.

Strategic Mistake: “Waiting It Out” and Email Chaos

The most common mistake at present is: “I will simply print the e-invoice and file it.” Caution: For a real XML e-invoice, that is a violation of the GoBD. The original is digital and must be retained digitally. The printout is only a copy with no evidentiary value.

Anyone who receives e-invoices by email and lets them languish in the inbox risks losing the input VAT deduction during a tax audit.

The clean separation:

1. Incoming invoices: Centralize them through the DATEV e-invoicing platform.
2. Outgoing invoices: Automate them through Autaxo (PDF/A-3).

Checklist: Ready for E-Invoicing in 3 Steps

• ☐ Step 1 (receipt): Ask your tax advisor whether you have access to DATEV Unternehmen online or the e-invoicing platform. If not, apply for access.
• ☐ Step 2 (email): Set up a central invoice email address, such as rechnung@autohaus-muster.de, and ideally forward it directly to DATEV.
• ☐ Step 3 (issuance): Use the PDF/A-3 (ZUGFeRD) format in Autaxo. This prepares you for every B2B customer, regardless of when the obligation begins to apply to you.
• ☐ Bonus (avoid errors): Check the invoice wording for the tax case before sending
