xrio

xrio validates and creates German e-invoices and renders them as PDF, straight from the chat.

Validate: ChatGPT sends an XRechnung or a ZUGFeRD / Factur-X PDF to xrio and gets every finding back in the norm's original wording, with the business term and the XML path. xrio checks against EN 16931 and XRechnung with the official KoSIT validator. A PDF without invoice XML is reported as "not an e-invoice".

Create: invoice data becomes an XRechnung, a ZUGFeRD PDF or both. All fields of EN 16931 and eight invoice types, from the invoice to the final construction invoice, are supported. xrio recalculates the amounts and validates every file before returning it; if the data does not meet the rules, all findings come back at once instead of a file. Company data, bank account and logo are stored in the xrio account and placed on the invoice automatically.

Make readable: an e-invoice XML can be turned into a PDF view, in the xrio layout with a GiroCode or in the official KoSIT layout.

xrio exchanges files through a single-use upload link and a time-limited download link, both on api.xrio.de. Result files are kept for seven days and then deleted. xrio does not analyse your data with AI and does not train models. It quotes legal sources only from official texts and gives no tax advice.

xrio is for businesses that issue or receive e-invoices in Germany. It needs an xrio account at app.xrio.de with the company's data; sign-in happens in the browser. All servers are located in Germany.
