EN 16931 is the European standard for electronic invoicing, required for public procurement across the EU. It defines the semantic data model and technical requirements for e-invoices to ensure cross-border interoperability.

Is EN 16931 mandatory?

Yes, any business sending invoices to public authorities in the EU is required to comply with EN 16931. Additionally, from July 2030, all cross-border B2B transactions within the EU will require EN 16931-compliant e-invoices.

Do I need technical skills?

No. Our tool is designed to be user-friendly. Simply upload your PDF, and we'll handle the rest.

How long does conversion take?

The conversion from PDF to different EN 16931 e-invoice standards (e.g., XRechnung, ZUGFeRD) typically takes 10-30 seconds. You can download your e-invoice within seconds.

How is my data protected?

We use state-of-the-art encryption and security measures to protect your data. Uploads are processed securely and are not kept permanently; task and result artifacts may remain available briefly for retrieval and troubleshooting, normally up to 10 minutes.

Is my invoice information stored?

We do not create a permanent invoice archive. Conversion data and task/result artifacts are retained only briefly to deliver downloads and support retries, normally up to 10 minutes, then deleted or expired.

What happens if there's an error in conversion?

Our AI is highly accurate, but in the rare case of an error, you can manually edit the output before finalizing. We also provide customer support to assist with any issues.

Can I use this for multiple invoices?

Yes, our service is designed to handle both single and batch conversions. You can upload multiple PDF invoices and convert them to the e-invoice format of your choice.

What is the difference between XRechnung and EN 16931?

EN 16931 is the European e-invoicing standard, while XRechnung is Germany's national implementation of this standard. XRechnung adds specific German requirements while maintaining compatibility with EN 16931.

Keep your current invoicing process and export a standards-aligned e-invoice when needed.
