For many small businesses, paying suppliers is just part of the weekly routine. An invoice lands, someone checks it, the payment gets approved, and the day moves on. The problem is that cybercriminals know exactly how normal and time-pressured that process can be.
For many small businesses, paying suppliers is just part of the weekly routine. An invoice lands, someone checks it, the payment gets approved, and the day moves on. The problem is that cybercriminals know exactly how normal and time-pressured that process can be.
One of the most common and costly scams aimed at SMEs is invoice fraud, sometimes called payment diversion fraud. It usually starts with an email that looks genuine. It might appear to come from a real supplier, a contractor, or even someone senior inside your own business. The message says that bank details have changed and asks for the next payment to be sent to a new account.
If nobody stops to verify it properly, the money can go straight to a criminal instead.
For a small business in Bolton, Bury, or elsewhere in the North West, that kind of loss can hurt far more than just the monthly numbers. It can affect cash flow, delay projects, strain supplier relationships, and create a stressful clean-up that takes far longer than the payment itself. The good news is that preventing this type of fraud often comes down to one practical habit: never update payment details from email alone.
Invoice fraud does not usually rely on flashy hacking. It often succeeds because it looks ordinary.
A criminal might:
That is what makes it dangerous. The message may not look obviously suspicious. It may mention a real invoice, a real job, or a real supplier your business already uses.
Imagine a small construction firm in Greater Manchester waiting to pay a subcontractor. The accounts team receives a polite email saying the supplier has changed banks and needs payment sent to a new account today. Nothing in the message seems especially dramatic. The amount is expected. The sender name looks familiar. If the team is juggling payroll, supplier calls and customer work at the same time, it is easy to see how the payment could be released without a second thought.
Unfortunately, that second thought is often the difference between business as usual and a serious financial loss.
The safest approach is straightforward:
If bank details change, verify the request outside email before any payment is made.
That means using a trusted contact method you already hold on file, not the phone number or reply address included in the message itself.
In practice, that might mean:
This is not about distrusting every supplier. It is about recognising that email on its own is not strong enough proof when money is involved.
You do not need a complex finance department to reduce the risk. A simple checklist can make a real difference.
Do not let anyone change supplier payment information casually or informally. Decide who is allowed to approve changes and how verification must happen.
Even in a business with only 5 to 50 staff, a basic rule helps: no bank detail changes are actioned until someone has confirmed them by phone using trusted contact information.
Urgency is one of the biggest warning signs in fraud. If the message says payment must be made immediately, or that a project will be delayed unless the new details are used today, treat that as a reason to be more careful, not less.
A rushed process is exactly what a fraudster wants.
For higher-value payments, ask for a second internal check. One person verifies the change, another confirms the payment. That small separation reduces the chance of a mistake slipping through.
Your accounts team should not be the only people aware of this risk. Office managers, operations staff, directors and anyone who approves payments should understand how convincing these emails can be.
A short briefing can go a long way. Show people the pattern:
Once people know what to watch for, they are far less likely to be caught out.
This issue is not just about finance. It is also part of a wider cybersecurity picture. Strong email security, multi-factor authentication, account monitoring and sensible access controls all help reduce the risk of compromised accounts being used in the first place.
That is where managed IT support becomes valuable. Good protection is not only about blocking attacks. It is also about putting practical processes around day-to-day business activity, so your technology is managed the right way.
If your business pays suppliers regularly, take ten minutes this week to review how bank detail changes are handled.
Ask yourself:
If the answer to any of those questions is uncertain, that is a good place to start.
For many SMEs, one written process and one quick conversation with staff can remove a surprising amount of risk. And when that process is backed by strong email security and sensible IT controls, your business is in a much better position to avoid a preventable loss.
If you would like a practical review of the weak points in your current setup, Managed IT Support can help you look at email security, account protection and payment-related risks in a straightforward, business-friendly way.
