do you suspect fraud? here’s a response playbook

USD $534 billion. That was the annual cost of fraud in a single year, according to a 2025 survey, averaging to 7.7% of a company’s annual revenue. Behind that number are businesses of every size — from multinationals to small enterprises — facing damaged reputations, broken employee trust, and in many cases, losses they never fully recover from. For small businesses, fraud losses are often enough to threaten their very survival.

Fraud takes many forms, but it is broadly categorized by its source: external threats such as scams, account takeover, or synthetic identity fraud; or internal breaches such as asset misappropriation. Both categories are growing. Both can be devastating.

Data reveals a sharp escalation in specific points of vulnerability. While scams and authorised fraud led the losses, digital account takeover saw a staggering 21% surge in only twelve months.

Yet, for all its scale, fraud rarely announces itself openly. It often starts with something small. A vendor invoice that looks slightly off; a colleague working unusual hours; an audit flagging a number that doesn't add up. By the time the pattern becomes visible, the clock has already been ticking. How an organisation responds in the hours and days after suspicion arises is important. It can mean the difference between a contained incident and a costly crisis.


When fraud is suspected: the first steps

When fraud is suspected, the instinct is to confront the suspect, pull records, and escalate loudly. This approach can be counterproductive. Instead, the response should be guided by a methodical process:

  1. Contain the threat: Restrict system access, place holds on relevant transactions, or flag accounts for monitoring, without alerting the suspect.
  2. Assess the situation: Determine which laws or policies were violated and identify the suspects. Look for behavioral red flags, such as employees living beyond their means, refusing to take leave, or having unusually close vendor relationships. While not proof of guilt, these details help focus the investigation.

Once these initial steps are taken, assemble a tight, cross-functional team. At a minimum, this should include legal counsel, internal audit, HR, and digital forensics. For high-stakes cases, hire external forensic accountants to ensure credibility and to fill technical gaps. Keep the circle of communication small; every additional person informed is a potential leak.


The investigation process

With the team and plan in place, the investigation can begin.

  1. Secure the evidence
  2. Evidence is the foundation of everything that follows. Identify and preserve all relevant material—including financial records, digital communications, and access logs—before it is altered. Digital evidence requires extra care, as metadata and timestamps are easily corrupted. Establish a chain of custody immediately by logging what was collected, where, when, and by whom. This ensures evidence remains admissible in court.


  3. Conduct interviews
  4. Interviews reveal what spreadsheets cannot, but they must be handled delicately. Done poorly, they alert suspects or intimidate witnesses. Start with peripheral witnesses, moving gradually toward the primary suspect. Keep the questioning neutral and document everything, including the interviewee's demeanor and any inconsistencies with the evidence.


  5. Analyse data and apply forensic accounting
  6. This is where the numbers tell the story. Use data analysis and forensic accounting to detect anomalies such as unusual transaction spikes, duplicate payments, fictitious vendors, or ghost employees. Techniques like Benford's Law analysis can detect manipulated numbers that would otherwise go unnoticed. For complex cases, engage a certified forensic accountant. Their findings carry the professional weight needed to withstand legal scrutiny.


  7. Document the investigation
  8. Every step of the investigation must be documented as it happens. This means maintaining a detailed log of every decision, action, and interview. This creates an audit trail that proves the investigation was fair and methodical, protecting the organisation against claims of bias. Treat every entry as if it will be reviewed by a judge or opposing counsel.


  9. Create a clear and concise report<
  10. The final report should be a factual, objective record of the findings, written in plain language without jargon or assumptions. Limit distribution to a strict need-to-know basis.
    Underpinning every step must be a commitment to legal compliance and ethical conduct. A clear, documented fraud policy — one that defines what constitutes fraud and outlines the response process — is invaluable here. If your organisation does not have one, creating it should be prioritised.


Post-investigation: accountability and prevention

Where fraud is substantiated, respond decisively and consistently. This may involve employment termination, suing for losses, or police referral.
Beyond the immediate action is diving deep to understand what made fraud possible. Close the control gap that was exploited and review related processes for similar vulnerabilities. Treat remediation as a formal project with assigned ownership and follow-up review. This is often the time to evaluate fraud management solutions and upgrade to tools that provide better real-time visibility.


Conclusion

Fraud is a systemic risk. A structured, disciplined response protects more than just the organisation's finances; it safeguards reputation and long-term integrity. For the longer term, prevention requires a layered approach: leadership that models ethical behavior visibly, regular employee training on fraud awareness, periodic fraud risk assessments, a robust fraud management system, and internal controls.

By investigating methodically and responding decisively, you turn a painful incident into an opportunity to build a business that is significantly harder to defraud in the future.
