PDF E-Invoice Validator : Validate ZUGFeRD & XRechnung

PDF E-Invoice Validator – Your solution for validating ZUGFeRD & XRechnung!

E-invoices are the future of digital invoicing. However, not every electronic invoice meets the strict requirements of DIN EN 16931 or the ZUGFeRD standard. This is where the 7-PDF E-Invoice Validator comes into play!

Our software reliably and quickly checks whether your e-invoice is formally correct. The tool validates both the XML structure and PDF/A-3 compliance and provides you with a detailed validation report – ensuring legally compliant invoicing.

Why use the 7-PDF E-Invoice Validator?

🔍 Because we validate deeper than many others! While many online validators only check the technical structure (XSD) of your e-invoice, our 7-PDF E-Invoice Validator goes one step further. By integrating the official EN16931 Schematron rules, we also validate the content accuracy of your ZUGFeRD or XRechnung – exactly according to current EU standards. Outdated profiles like ZUGFeRD 1.0 / 2.0 or XRechnung 1.x are no longer validated and are clearly marked as non-compliant.

This way, you can reliably determine whether your e-invoice is truly compliant – even if other validators mistakenly mark it as “valid.” Only a semantically validated invoice guarantees successful processing by public authorities or large invoice recipients.

• ✅ EN16931 compliance check – Easily verify whether your invoice meets the requirements for electronic invoicing.
• ✅ Validation of ZUGFeRD & XRechnung – Supports all common e-invoice formats including Factur-X.
• ✅ Only technically and formally valid formats are accepted – Outdated profiles (e.g. ZUGFeRD 2.0, XRechnung 1.x) are consistently marked as invalid.
• ✅ Schematron rules for content validation – Checks mandatory fields, total logic, profile rules, and more.
• ✅ PDF/A-3-B and PDF/A-3-U check – Verifies if your PDF complies with the archivable PDF/A-3 standard.
• ✅ Detailed validation reports – Get clear feedback about the compliance of your invoice documents.
• ✅ Visual review of your e-invoice – Convenient visual inspection via integrated e-invoice viewer.
• ✅ Simple drag & drop – Drag your file into the tool and validate it in just a few seconds.
• ✅ Ideal for businesses and service providers – Whether sender or receiver: avoid invalid invoices and unnecessary returns.

Note: The validator uses the official EN16931 Schematron for CII (UN/CEFACT) and also supports validation of new profiles such as ZUGFeRD 2.3.2 Extended upon request. All validations are fully compliant with the European standard and offer the highest level of validation security – far beyond simple XSD checks.

Validate e-invoices – Avoid errors!

With 7-PDF E-Invoice Validator, you ensure that your e-invoices are legally compliant, error-free, and machine-readable – perfect for electronic invoicing with authorities, companies, and business partners.

7-PDF E-Invoice Validator – Command Line Mode (CLI)

Use the 7-PDF E-Invoice Validator directly in your console or automated workflows to validate e-invoices in PDF or XML format quickly and reliably. In this tutorial we will show you in a practical way here how we can create a PDF ZUGFeRD document using the pure print output of our PDF printer 7-PDF-Printer and "validate" it fully automatically, thereby formally checking it against the DIN EN 16931 schema. Our freeware ZUGFEeRD4Excel for generating e-invoices from Microsoft Excel also uses our console-controlled tool for electronic verification of your generated (e)-invoice.

Usage:

        
SevenPDFValidator.exe
            
  -mode "<gui|console|hidden>"
            
  -infile "<File>"
            
  [-logfile "<FilePath>"]
            
  [-report "<DirPath>"]
            
        
    

• -mode <gui|console|hidden> → Required. Defines the display mode:
  • gui (default): Graphical User Interface
  • console: Console mode without GUI
  • hidden: Hidden mode (e.g., for batch processing)
• -infile "<File>" → Required. File to be validated. Supported formats: *.xml and *.pdf.
• -logfile "<FilePath>" → Optional. Recommended for -mode "hidden". Saves output to a file for later analysis.
• -report "<DirPath>" → Optional. Directory path for saving the validation report. If not specified, only exit codes are returned.

Example:

        

        SevenPDFValidator.exe
        
  -mode "console"
        
  -infile "invoice.xml"
        
  -logfile "C:\temp\validation.txt"
        
        
    

✅ Runs the validation in console mode and saves the result to validation.txt.

Exit Codes & Meaning:

Code	Meaning
0	✅ E-invoice is valid
1	❌ E-invoice is invalid
2	⚠️ Error while executing. Check the log file
3	🔑 License required

Perfect for Automation!

The CLI mode allows easy integration into scripts, batch processes, or ERP systems for automated invoice validation.
