Visor XRechnung y ZUGFeRD

XRechnung and ZUGFeRD (Factur-X) represent the official electronic invoicing standards across Germany and the broader European Union under the European standard EN 16931. Public administration bodies across German federal, state, and municipal tiers mandate structured XML data for all public procurement contracts.

Unlike traditional PDF invoices where text is visually rendered for human eyes, an electronic invoice packages structured commercial data into semantic XML nodes. This structure allows enterprise accounting systems to parse line items, tax rates, bank payment details, and buyer references without manual data entry.

This XRechnung and ZUGFeRD Viewer provides instant visualization of German electronic invoices directly in your browser. It parses both Universal Business Language (UBL) and UN/CEFACT Cross Industry Invoice (CII) syntax, extracts embedded XML from hybrid ZUGFeRD PDF files, and validates core computational totals without uploading sensitive financial records to external servers.

For creating initial commercial billing documents, use the invoice maker. To inspect related structured data feeds, pair this viewer with the xml formatter and sales tax calculator.

Especificaciones de ingeniería y detalles de ejecución

Supports EN 16931 semantic data models across UBL Invoice-2.1 syntax (urn:oasis:names:specification:ubl:schema:xsd:Invoice-2) and UN/CEFACT CII syntax (CrossIndustryInvoice).

Parses the German national extension specification CIUS (Core Invoice Usage Specification) XRechnung rules version 2.0 through 3.0.

Handles ZUGFeRD 2.0, 2.1, and 2.2 profiles including MINIMUM, BASIC, BASIC WL, EN 16931, and EXTENDED.

Extracts embedded factur-x.xml and zugferd-invoice.xml data streams from PDF/A-3 container files in client-side memory using pure ArrayBuffer parsing.

Performs mathematical integrity checks across Net Amount, Total Allowance / Charge amounts, VAT Category Breakdown, and Final Gross Payable Amount.

Identifies and displays buyer reference codes (BT-10 Leitweg-ID) required by German federal portals (ZRE and OZG-RE).

Privacidad de datos y aislamiento en memoria

Invoice parsing executes completely inside browser JavaScript memory using the native HTML5 DOMParser API.

Zero invoice data, vendor names, recipient identities, line item costs, or bank account IBANs are sent to remote servers.

Compatible with strict corporate data governance and EU General Data Protection Regulation (GDPR) compliance mandates.

Casos de uso comunes en producción

• Contractors, freelancers, and small businesses inspecting received XRechnung files before submitting claims to public authorities.
• Accounting departments validating vendor invoices and verifying line item calculations prior to posting into ERP ledgers.
• Software developers debugging e-invoicing export routines and verifying UBL/CII node structures against real-world parser outputs.

Casos extremos y límites operativos

• Hybrid ZUGFeRD PDFs with multiple attachments: The parser isolates standard factur-x.xml or zugferd-invoice.xml streams while skipping auxiliary image attachments.
• Mixed tax rate invoices: Line items carrying zero-rated cross-border exemptions, standard 19% VAT, and 7% reduced VAT calculate independent taxable subtotals.
