Verification Checklist
    ⚠
    This is an assistant checklist, not a guarantee. Invoice Guard helps surface common red flags — it cannot detect all fraud types, and a low risk score does not mean a document is authentic. Always verify payment changes by phone using a number you already have on file — never a number provided in the suspicious message itself.

    Fraud emails love unanswered phones

    Payment-redirect attacks often succeed when employees can't quickly reach a vendor to verify. The AI Front Desk answers every call, text, and message to your business 24/7 — so your team isn't left guessing when a suspicious email arrives on a Friday afternoon.

    Common Questions

    Is Invoice Guard free?
    Yes — completely free, no account required. Your text is analyzed in memory and never stored.
    What types of fraud signals does it check for?
    Bank-detail-change language, wire-only or gift-card payment demands, urgency and pressure phrases, lookalike or spoofed email domains, missing invoice reference numbers, generic impersonal greetings, and suspiciously round dollar amounts. It does not claim to catch every fraud type.
    Does my text get saved?
    No. Your text is passed to our analysis server, checked in memory, and discarded. We log only text length and processing time — never the content itself.
    Should I act on the risk score alone?
    No. A low score does not mean a document is authentic. Always verify payment instructions by calling the vendor on a phone number from your own records — not one provided in the email you're checking.
    Can this detect all invoice fraud?
    No tool can, and we do not claim otherwise. Fraud tactics evolve constantly. Invoice Guard surfaces common patterns and gives your team a structured checklist. Human judgment remains essential.
