InvoiceXML serves as an API-centric platform tailored for achieving e-invoice compliance across Europe. Its REST API is capable of generating, validating, and converting a wide array of formats that fall under EN 16931, including Factur-X, ZUGFeRD, XRechnung, UBL, and CII. The generation process takes in clean JSON data and produces either a compliant XML document or a PDF/A-3 hybrid invoice, complete with embedded XML following specific formatting guidelines. Validation is conducted using the official Schematron rulesets, which not only deliver structured results but also provide accessible explanations in plain language alongside the raw outputs of the rules. For format conversion, the API endpoint (POST /v1/convert/{from}/to/{format}) allows the transformation of any supported format into another via a unified internal representation. Additionally, a dedicated namespace, /v1/transform/, facilitates AI-driven extraction from older PDF invoices into organized XML. Moreover, No-Code integrations enable users without programming skills to access core functionalities seamlessly. The MCP server supplies a robust compliance toolkit designed for AI-assisted workflows, ensuring that the platform is consistently aligned with the latest standards, requiring no ongoing maintenance for users. This approach not only simplifies the compliance process but also enhances efficiency for businesses navigating the e-invoicing landscape.
