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?

For public-sector invoices, effectively yes: EU member states must be able to receive EN 16931-compliant e-invoices, and national rules such as Germany’s XRechnung turn that into a concrete obligation for suppliers. From July 2030, cross-border B2B transactions within the EU will also require EN 16931-compliant e-invoices.

Do I need technical skills?

No XML coding is needed. Upload the PDF, then check the extracted supplier, buyer, amounts and tax details against the original before downloading. If the tax treatment is unclear, ask the person responsible for your accounts.

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 normally remain available for up to 10 minutes. Separate encrypted debug bundles may be retained for up to 14 days.

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. Separate encrypted debug bundles may be retained for up to 14 days.

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.

Ready for review in under 30 seconds

Most invoices are ready for review in under 30 seconds.

The integrated reviewer highlights missing or non-compliant fields, and every value — names, amounts, line items — stays editable until you export.

Handle repeat work faster

Upload up to 10 invoices in one batch when you need to clear routine work in less time.

A PDF is not an e-invoice

Since 1 January 2025 a plain PDF is an “other invoice”. An e-invoice exists only when it is issued, sent and received as structured EN 16931 XML — for example XRechnung (UBL or CII) or ZUGFeRD/Factur-X with conforming XML, not MINIMUM or BASIC-WL.

BMF FAQ, questions 2 and 7

XRechnung or ZUGFeRD?

Pick by recipient. The XML must meet EN 16931.

Current versions: XRechnung 3.0.2, ZUGFeRD 2.5 / Factur-X 1.09.

Authority / B2G

XRechnung is the default path to public buyers. Put the Leitweg-ID in BuyerReference.

PDF to XRechnung

B2B with a readable PDF

ZUGFeRD gives a readable PDF/A-3 with embedded XML. For e-invoice status the XML leads, not the PDF image.

PDF to ZUGFeRD

France

Factur-X is the Franco-German hybrid format. We generate and check the file; we do not transmit to Chorus Pro or a PDP.

PDF to Factur-X

The BMF accepts ZUGFeRD from version 2.0.1 as an e-invoice when the XML meets EN 16931. MINIMUM and BASIC-WL do not count. XRechnung remains the usual B2G path.

Frequently Asked Questions

Yes. In a supported WebMCP browser, ChatGPT can guide the existing page workflow from conversion through review, validation, generation, and download. You first select one PDF in the normal file picker. ChatGPT can then read and edit the review data. Final generation and download each require explicit confirmation and a short-lived token bound to the current validated invoice. The normal web credit rules still apply. Browser and model availability can vary.
