  • explain_ruleExplain an e-invoice ruleread-only

    Explain one EN 16931 / XRechnung / Peppol business rule by its code (e.g. BR-DE-15, BR-CO-10, PEPPOL-EN16931-R010): what it requires, why invoices typically break it, and how to fix it, with a link to the full page. Case does not matter. Schema findings (cvc-*) have no explanation.

  • generate_invoiceGenerate an e-invoice

    Produce an e-invoice as `ubl` or `cii` XML or a ZUGFeRD hybrid PDF (`zugferd`) from invoice data: an XRechnung for a public-sector buyer (profile `xrechnung`, the default), a plain EN 16931 invoice for a business (profile `en16931`). Totals are computed server-side in decimal arithmetic, and the document is validated against the official rules before it is returned. Data the rules do not permit is refused with the broken rules and how to fix each. Needs the user's NormAPI account; each document counts against the monthly allowance (50 free).

  • parse_invoiceRead an e-invoice into dataread-only

    Read a received e-invoice — XRechnung or any EN 16931 invoice as UBL or CII XML, or a ZUGFeRD/Factur-X PDF — into structured data. `invoice` is in exactly the shape generate_invoice takes (fields the document lacks are left out); `stated` has the totals, the VAT breakdown and each line net as the document states them, as exact decimal strings; `notMapped` lists by path every value of the document the data does not carry. Send the XML as text in `xml`, or the PDF base64-encoded in `pdfBase64` — exactly one. `validate: true` adds the KoSIT verdict. Free, no account needed, 5 MB at most.

  • validate_invoiceValidate an e-invoiceread-only

    Check an XRechnung (UBL or CII XML) or a ZUGFeRD/Factur-X PDF against the official KoSIT rules. Returns the verdict, the rule set version, and every finding; each business-rule finding comes with a plain-language meaning, cause and fix. Send the XML as text in `xml`, or the PDF base64-encoded in `pdfBase64` — exactly one. Free, no account needed, 5 MB at most.
