Hi Product Hunt 👋

I'm Taha, and I built eInvoiceTool.

Why: e-invoicing became mandatory across Europe – Germany (since 2025 every business must be able to receive e-invoices), Belgium (Peppol since January 2026), Poland (KSeF since February 2026) and France (receiving since September 2026). The invoice is now an XML file. If you're a small business, freelancer or accountant without the "right" software, opening one shows you only code. Most free viewers ask you to upload the invoice to someone's server – not great for financial data.

What it does:

📄 Viewer – drop an XRechnung, ZUGFeRD / Factur-X PDF, Peppol UBL or KSeF file and read it like a normal invoice. Print or save as PDF, or pull the XML out of a ZUGFeRD PDF.
✅ Validator – checks the file against the official XML schemas and EN 16931, XRechnung and Peppol rules, and explains each error in plain language (with a page per common error code).
🔒 Private by design – everything runs in your browser. Files never leave your computer, no sign-up, no tracking cookies.

Who it's for: small businesses receiving e-invoices, accountants and bookkeepers, and developers testing their own e-invoice output.

What I'd love to hear: which format or feature is missing for you? Next on my list are showing files attached inside invoices and a UBL ⇄ CII converter – tell me what would help you most.

Thanks for taking a look!
