What Conformo does not do yet

Said plainly, so nobody finds out the hard way.

• It does not send invoices. No Peppol access point, no French PA/PDP, no KSeF, no SdI, no ZRE/OZG-RE upload. It makes and checks documents; you send them.
• No FatturaPA (Italy) or FacturaE (Spain) at all. conformo requirements IT says so instead of pretending.
• KSeF FA(3) (Poland) is partial: domestic PLN invoices only (standard rates, 0 %, exempt), checked against the XSD only, not readable back, and not submitted to KSeF.
• Belgium's 2026 B2B mandate needs Peppol delivery. The library writes Peppol BIS Billing 3.0 UBL; delivering it needs an access point.
• No XSD check in the browser. The app and the validator page run the full official Schematron; the XML schema check runs in Node (library, CLI, MCP, HTTP API).
• The PDF's labels are English ("INVOICE", "BILL TO") for every customer, although the app itself is English and German.
• The web app does not offer VAT category K (intra-EU supply of goods), because the form does not yet ask for the delivery date and country it requires. The library supports it.
• Not a compliance guarantee. valid: true means the listed official rule sets and the XSD passed. Whether a tax authority, buyer or network accepts an invoice also depends on things no validator sees.
• Not accounting software. No bookkeeping, payroll, expenses, inventory, CRM or time tracking, and no account or server is required for anything.
