How PDFA-3 and XML Integration Simplifies E-Invoicing for European Businesses
Meta Description:
Learn how PDFA-3 and XML integration using VeryPDF tools simplify e-invoicing for EU businesses, ensuring EN 16931 compliance and reducing manual workload.
Every invoice used to feel like a mini disaster
Back when I was managing document workflows for a mid-sized logistics firm in Germany, our invoicing process was a total mess.
We were manually generating invoices in Word, exporting them to PDF, then using another software to attach XML data for compliance.
The process was slow.
Our accounting team dreaded end-of-month reconciliations. We constantly had errors in XML structures. Some invoices weren’t compliant with EN 16931, and it cost us dearly rejections, fines, wasted time.
That’s when I knew we needed a better way.
And that’s when I stumbled on VeryPDF’s PDF Solutions for Developers.
The tool that changed our e-invoicing game
I wasn’t expecting much at first.
But once I got my hands on VeryPDF’s ZUGFeRD-compliant PDF/A-3 generation toolkit, I knew this wasn’t just another PDF gimmick.
It let us do everything generate invoice-ready PDFs, attach machine-readable XML data, stay compliant with Factur-X, X-Rechnung, and more all from one place.
No more flipping between tools.
Just pure, structured output every single time.
Who needs this?
If you’re a:
-
Finance lead or controller in a European company
-
Developer building ERP or invoicing integrations
-
IT manager trying to automate invoice compliance
-
Freelancer or SME owner juggling cross-border e-invoicing
…this is for you.
Whether you’re dealing with B2B, B2G, or cross-border vendors, VeryPDF makes e-invoicing effortless without needing to be an XML ninja.
What it actually does (and how I used it)
Here’s where VeryPDF’s solution stood out from the crowd:
PDF/A-3 generation with embedded XML
We needed invoices that weren’t just readable by humans, but also parsable by other systems.
VeryPDF allowed us to embed XML inside a PDF/A-3 wrapper, perfectly aligned with ZUGFeRD and Factur-X specs.
All we had to do was:
-
Feed the tool a standard invoice PDF
-
Attach the structured XML (generated from our accounting system)
-
Let VeryPDF wrap it all into a PDF/A-3-compliant file
No manual merging. No compliance worries. Just done.
Support for multiple formats (ZUGFeRD, X-Rechnung, Factur-X)
We were shipping goods across Germany, France, and Italy all with slightly different invoice requirements.
VeryPDF handled them all.
Need a ZUGFeRD “Comfort” profile invoice? Sorted.
Need to comply with X-Rechnung for a German municipality? No problem.
Need Factur-X for a French customer? It’s built in.
The flexibility meant we didn’t have to maintain separate systems for each market.
Developer-first integration
Let’s be real. Most invoicing solutions are either:
-
Built for end users (drag and drop tools, not programmable)
-
Or designed like it’s still 2005 clunky APIs, poor docs
VeryPDF was a breath of fresh air. I had it:
-
Integrated into our C# backend in under two days
-
Running batch jobs to convert 1,000+ invoices/day
-
Validating outputs automatically with conformance checks
And the docs? Actually helpful.
The moment everything clicked
There was one moment that really stuck with me.
A French government client had rejected three of our invoices for not following the Factur-X extended profile.
I took one of the rejected PDFs, fed it through our VeryPDF-powered toolchain, embedded the correct XML, generated the new PDF/A-3, and resubmitted.
Not only was it accepted the government system auto-processed it, and we got paid faster than ever.
That was the “we’re never going back” moment.
Why other tools don’t cut it
We tried other options.
Some would almost generate a compliant file but you’d need another step to validate it.
Some were SaaS tools not ideal for sensitive customer invoice data.
Some worked until you needed to do batch jobs or script something more complex.
VeryPDF nailed the balance between powerful features and simple control. We owned our infrastructure, we didn’t send data to third parties, and we had complete command over outputs.
TL;DR What this solves for you
Here’s what VeryPDF’s PDF/A-3 and XML integration solution crushes:
-
No more manual invoice formatting
-
No rejected invoices due to missing compliance
-
Batch invoice generation fast
-
Easy API and language support (.NET, Java, Python, etc.)
-
ZUGFeRD and EN 16931 compliance out of the box
-
XML + PDF = one file, legally solid and machine-readable
Why I’d recommend it
If you’re doing e-invoicing in Europe and still using multiple tools, or worse manual steps you’re wasting time, risking compliance, and creating problems you don’t need.

FAQs
1. What is PDF/A-3, and why is it important for e-invoicing?
PDF/A-3 is a standardised version of PDF used for archiving. It allows embedding XML files, making it ideal for e-invoicing, where structured data must travel with the readable invoice.
2. What’s ZUGFeRD and how does VeryPDF support it?
ZUGFeRD (and its international sibling Factur-X) is a format combining PDF and embedded XML. VeryPDF supports all profiles (Basic, Comfort, Extended) and ensures full compliance.
3. Can I automate invoice generation with VeryPDF?
Yes. VeryPDF offers command-line tools and APIs in multiple languages (C#, Java, Python) to automate batch invoice generation and XML embedding.
4. Is this only for large enterprises?
Nope. We started using it as a mid-sized business with no in-house PDF expertise. The tools scale from small batches to massive automated jobs.
5. What’s the difference between X-Rechnung and ZUGFeRD?
X-Rechnung is used for public sector invoices in Germany. ZUGFeRD is more for B2B. VeryPDF supports both, so you don’t have to worry.
