InvoiceXML

InvoiceXML is a REST API and compliance platform built for developers and businesses navigating European e-invoicing mandates. As EU member states roll out mandatory e-invoicing requirements (Germany, France, Belgium, Poland, and others), businesses need machine-readable, structured invoices in formats like ZUGFeRD, Factur-X, XRechnung, UBL, and Peppol. InvoiceXML handles all of it through a single, well-documented API. What you can do with InvoiceXML: Generate fully compliant e-invoices in ZUGFeRD, Factur-X, XRechnung, UBL, and Peppol formats Validate existing XML invoices against official Schematron rules and return structured error reports Convert between e-invoice formats (e.g. UBL → ZUGFeRD) Render PDF previews of structured invoices Automate invoice workflows via Zapier integration Free tools, no account needed: 🇩🇪 Create and validate ZUGFeRD invoices → getzugferd.com 🇫🇷 Create and validate Factur-X invoices → getfacturx.com Built for ERP integrators, accounting software vendors, freelancers selling into Europe, and any SaaS product that needs to issue or process compliant invoices across borders. → invoicexml.com
