AI-enhanced fraud is changing how criminals target finance teams, particularly Accounts Payable (AP) departments. Attackers can now create convincing emails, realistic invoices and cloned voices that bypass the warning signs businesses once relied on.
According to the FBI’s 2025 Internet Crime Report, business email compromise (BEC) cost organisations more than US$3 billion last year. Furthermore, as artificial intelligence becomes more sophisticated, the question is no longer whether your team can spot a suspicious email. Instead, it is whether your payment process can stop fraud before money leaves the business.
Here at Microsavvy, we believe effective invoice fraud prevention requires secure processes, modern cybersecurity controls and a workplace culture that supports verification before payment.
Small businesses across the Sunshine Coast need to make sure they have a plan in place. Consequently, organisations that fail to review their accounts payable procedures may become easier targets for AI-powered scams.
Why Accounts Payable Teams Are Prime Targets
Accounts Payable sits at the intersection of trust and urgency. AP teams process invoices, update supplier details and approve payments, often under tight deadlines.
For cybercriminals, that creates an ideal opportunity.
Most successful fraud does not involve hacking systems. Instead, attackers impersonate trusted suppliers, executives or colleagues to redirect payments or change banking details.
For many organisations, accounts payable fraud is now one of the most significant cyber risks facing finance teams. Furthermore, AI tools allow attackers to automate research, create convincing communications and mimic legitimate business interactions at scale.
As a result, what once required significant effort can now be generated in minutes.
How AI Is Changing Invoice Fraud
AI-Generated Emails That Look Genuine
Traditional phishing emails often contained spelling mistakes, poor formatting and generic greetings.
However, today’s AI-powered scams are very different.
Modern business email compromise attacks can mirror a supplier’s communication style, reference genuine projects and even include real invoice numbers. Consequently, these fraudulent requests often blend into normal business communications.
The Australian Cyber Security Centre explains that business email compromise often relies on abusing trust in normal business processes, including impersonating trusted staff or suppliers: ACSC business email compromise advice.
Payment Redirection and Invoice Fraud
One common form of accounts payable fraud involves changing supplier banking details.
For example, attackers may intercept or imitate legitimate communications and advise that payment information has changed. The invoice itself may be genuine, but the bank account is controlled by the criminal.
This is why invoice fraud prevention should never rely only on email instructions. Instead, businesses should verify banking changes through a separate, trusted channel.
Deepfake Voice Impersonation and Payment Fraud
Voice cloning technology has added a new dimension to payment fraud.
Using only a short audio sample, attackers can create convincing voice recordings or live calls that sound like company directors, managers or suppliers.
Therefore, organisations that rely on verbal approvals should review their procedures. As deepfake technology improves, payment security needs to evolve as well.
Why Traditional Fraud Checks Are No Longer Enough
Security awareness training remains important. However, AI has changed the threat landscape.
Many modern scams no longer contain obvious warning signs. Instead, messages are professionally written, contextually accurate and often based on information gathered from public sources or previous breaches.
As a result, businesses cannot rely solely on employees spotting suspicious communications.
Effective invoice fraud prevention focuses on creating processes that work regardless of how authentic a request appears.
For additional protection, Microsavvy offers cybersecurity services for Australian businesses that help reduce risk across email, cloud platforms and business systems.
Strengthening Your Invoice Fraud Prevention Controls
Make Verification Mandatory
One of the most effective fraud prevention strategies is independent verification of banking changes.
Any request involving supplier banking updates or urgent payments should require confirmation through an independent communication channel.
For example:
- Call the supplier using an existing contact number.
- Verify details with a known contact.
- Confirm requests through established business procedures.
This simple step can stop many business email compromise attacks before money leaves the organisation.
Use Multi-Factor Authentication to Prevent Accounts Payable Fraud
Multi-factor authentication (MFA) reduces the risk of compromised accounts being used to facilitate fraud.
Furthermore, strong authentication controls support broader cybersecurity objectives and help protect key business platforms.
Businesses should enforce MFA across:
- Microsoft 365 accounts
- Financial systems
- Payment platforms
- Supplier management portals
Furthermore, businesses should regularly review user access permissions, authentication settings and security policies to ensure critical systems remain protected against emerging threats.
Build a Culture That Supports Payment Fraud Prevention
Fraud prevention improves when employees feel comfortable questioning requests.
Likewise, leadership teams should actively encourage staff to verify unusual payment requests, regardless of who made them.
At Microsavvy, we’ve seen organisations reduce risk when leaders support strong verification processes. A delayed payment may be inconvenient. However, a fraudulent payment can be devastating.
Successful accounts payable fraud prevention depends on people, processes and technology working together.
Better Processes Reduce Business Risk
The FBI’s latest report included a dedicated AI section for the first time, recording more than US$893 million in AI-enabled scam losses.
While the technology behind invoice fraud continues to evolve, the most effective controls remain practical and achievable.
These include:
- Verifying banking changes independently.
- Enforcing multi-factor authentication.
- Separating payment approval responsibilities.
- Encouraging staff to challenge unusual requests.
- Reviewing financial controls regularly.
Ultimately, invoice fraud prevention is about making fraud difficult, regardless of how convincing a request appears.
Small businesses throughout the Sunshine Coast and South East Queensland should review their accounts payable procedures now. Otherwise, they risk becoming vulnerable to increasingly sophisticated scams.

Article FAQs
Why is accounts payable fraud increasing?
Accounts Payable teams control payments and supplier information, making them attractive targets for cybercriminals seeking direct financial gain.
Can staff training alone prevent AI-powered fraud?
No. While training remains important, businesses also need verification procedures, technical controls and strong payment processes.
Are deepfake voice scams a genuine risk?
Yes. AI voice cloning can mimic executives and suppliers. Consequently, verbal payment approvals are becoming increasingly vulnerable.
What is business email compromise?
Business Email Compromise (BEC) is a scam where attackers impersonate trusted contacts to trick employees into transferring money or disclosing sensitive information.
