    About This Skill

    Advanced Factur-X & ZUGFeRD E-Invoicing

    Modernize your billing stack for the French e-invoicing mandate with this professional-grade Factur-X engine. This skill automates the creation and validation of hybrid electronic invoices: a human-readable PDF/A-3 that carries a machine-readable EN16931-compliant XML file embedded within it.

    What it does

    • Generation: Produces valid PDF/A-3 files with embedded factur-x.xml (CII) using your structured JSON data.
    • Validation: Performs deep inspection of both PDF metadata (XMP extension schemas) and XML content to ensure EN16931 compliance.
    • Extraction: Automatically parses incoming Factur-X PDFs to extract structured data for seamless ERP or accounting integration.
    • Arithmetic Guardrails: Built-in logic cross-checks VAT rates, line items, and totals to prevent invalid invoice issuance.

    Why this is better than manual prompting

    Generating a Factur-X invoice requires precise PDF/A-3 metadata, specific XML namespaces (urn:cen.eu:en16931:2017), and exact attachment relationships (AFRelationship) that general LLMs cannot produce reliably on their own. This skill provides the specialized Python tooling and validation logic necessary to meet legal requirements for the upcoming French 2026-2027 rollout without relying on expensive third-party APIs.

    Supported Standards

    • Factur-X / ZUGFeRD (Hybrid Invoice Standard)
    • EN16931 (Cross Industry Invoice)
    • PDF/A-3 (ISO 19005-3)
    • French E-invoicing mandate requirements (SIREN/TVA integration)

    Use Cases

    • Generate French mandate-compliant hybrid PDF/A-3 invoices systematically.
    • Extract structured XML data from incoming Factur-X invoices for ERP entry.
    • Validate third-party e-invoices against EN16931 arithmetic and schema rules.
    • Ensure SIREN and TVA identifiers are correctly mapped to CII XML fields.
