Never pay a bank account you don’t recognise again.

Invoice fraud often starts with one email: “We have new bank details.” ClickCheck spots the difference from the known account and asks for a phone call first.

Bank details don’t match

This account number doesn’t belong to Vermeer Printing. Call the supplier on the number in your own records, not the one on the invoice or in the email.

ClickCheck · Demo Ltd

Example The invoice shows different bank details from the ones you have on file. ClickCheck compares them locally and asks for a call to the known number first.

Why this works

The check lives in the action, not in someone’s memory.

Every finance team knows the rule: changed bank details get a call, to the number you already had. Not the number in the email. The trouble is that such an email looks convincing and arrives just when it’s busy.

ClickCheck compares the account number on the invoice or payment screen with the numbers you know for that supplier. The comparison happens in the browser; the list of known numbers is only present in hashed form.

    Checklist

When the account differs

What the employee sees.

  1. A clear message

    “This account number doesn’t belong to this supplier.” In your own words, because you write the message.

  2. The instruction

    Call the phone number from your own records. Not the one on the invoice or in the email.

  3. Continue or stop, deliberately

    You can only continue after confirming the call was made. That choice is recorded.

Frequently asked questions

How does ClickCheck know which account number is known?

You enter or import known account numbers per supplier in the dashboard. The extension only receives a hashed version to compare against.

Does this work in our banking portal?

If the banking or accounting tool runs in the browser, you can put rules on it. You point at the field that holds the account number.
