Hi Product Hunt, I'm Sam, and I built Factline on my own in the Netherlands. AI agents are starting to pay invoices, onboard suppliers and send money. Before they do, someone should check the counterparty against official records, not guess. Factline does that in one call. The newest part is the supplier invoice check. You send what's on the invoice: supplier name or company number, VAT number, IBAN, and the sender's email. You get one verdict, pass, review or hold, with the source of each part: • the company in official registers (UK, Ireland, France, Norway, Finland, Czechia, Slovakia, Estonia, Poland, plus GLEIF worldwide) • sanctions and PEP screening of the company, its directors and its parent companies • whether the VAT number really belongs to that company • whether the IBAN is valid and in the same country, and for Polish suppliers whether it's registered to them on the government whitelist • whether the sender's email domain exists or is a look-alike • whether the supplier is on Peppol, now that Belgium and France require e-invoicing It works as an MCP server (Claude, ChatGPT, Cursor), a REST API, an n8n node and on Apify. You can start with a free trial key (2,000 credits a month, no card) or pay per call with x402. Things I'd love feedback on: which countries or checks you'd need next, and whether the verdicts are clear enough to act on.
