Invoice and payment scams

Stop fake invoices and bank detail scams

The costliest event scam is the simplest: a copy of your real invoice with different bank details. SummitShield stamps your real invoices, lets exhibitors check bank details in seconds, and closes the gaps that make the fakes convincing.

How the scam works

It usually goes like this

The copy

Your invoice, copied

Right down to the reference number.

The switch

“Our bank has changed”

A new account, often abroad.

The payment

Paid in good faith

The balance, or a deposit.

The fallout

Two invoices, one stand

And a difficult conversation for you.

Red flags to look out for

If you see any of these, stop and check before you pay or reply.

  • A change of bank details by email
  • An invoice from a slightly different address
  • Urgency around a balance or deposit
  • A request to keep it confidential
  • A PDF that’s been edited

Questions people ask

How do exhibitors check if an invoice is real?

They click the stamp on your invoice email, or forward the invoice to your check address. Bank details that aren’t yours are flagged straight away.

Do you store our bank details?

You can add the bank accounts you invoice from, so we can tell exhibitors whether one is yours. We only ever show the last few digits.
