E‑Rechnungs-Studio

InvoiceXML is an API-first platform for European e-invoice compliance. A single REST API generates, validates, and converts every major format covered by EN 16931: Factur-X, ZUGFeRD, XRechnung, UBL, and CII. Generation accepts clean JSON input and returns a compliant XML document, or a PDF/A-3 hybrid invoice with the XML embedded according to format-specific rules. Validation runs the official Schematron rulesets, and returns structured results plus user-friendly plain-language explanations alongside the raw rule output. Format conversion (POST /v1/convert/{from}/to/{format}) maps any supported format to any other through a canonical internal representation. A separate /v1/transform/ namespace handles AI-assisted extraction from legacy PDF invoices into structured XML. No-Code integrations expose the core operations to non-developers. MCP server provides the compliance toolkit for AI Agentic workflows. Always up to date with the latest standard requirements - zero maintenance.
