Free web validator

Validate XRechnung and ZUGFeRD invoices in the browser and make them easier to read.

How it works

• Upload an e-invoice with the upload button.
• XRechnung files usually use the xml extension, while ZUGFeRD documents are uploaded as PDF files.
• See the result below the »validate« button.

Alternatively you can paste XML directly into the text area. Signed-in users can also validate ZUGFeRD PDFs in the web validator.

Registration recommended

You can use the XInvoice validator without registration, but a free account gives you these benefits:

• Up to 60 validations per hour instead of 3.
• Detailed findings instead of only a status.
• A more relaxed anti-bot check with less waiting.
• Validation of ZUGFeRD PDFs directly in the browser.
• A later upgrade path into portal and API usage without a new account.
