  • Free email address. A real supplier uses a company email domain, not a free Gmail account. A classic sign of a faked invoice.
  • Vague line item. “Sundry works, as discussed” — no detail, a big round number. Always query undocumented charges.
  • The maths is wrong. VAT at 20% of £1,830 should be £366, not £420. If the numbers don’t add up, don’t pay.
  • No VAT number. They’re charging VAT but show no VAT registration number — if you charge VAT, you must display one.
  • “Bank details changed.” The number-one invoice scam. Always verify a bank change by phoning the supplier on a number you already trust — never the one on the invoice.
  • Urgency & pressure. “Pay within 24 hours” is designed to stop you checking. Genuine suppliers give normal payment terms.
