This year, the world marks International Fraud Awareness Week from 16th to 22nd November 2025, a timely reminder of the growing threat fraud poses to financial and accounting institutions. As organisations evolve and embrace digital systems, fraudsters are becoming more sophisticated, targeting weak points in financial processes—particularly invoice management, accounts payable workflows, and vendor verification systems.
Fraud in financial and accounting operations does not only lead to financial loss—it damages trust, disrupts operations, and exposes businesses to regulatory and reputational risk. Two of the most prevalent and costly forms of fraud today are invoice fraud and accounts payable (AP) manipulation.
The Rise of Invoice Fraud
Invoice fraud occurs when criminals deceive organisations into paying false or altered invoices. This may involve impersonating a legitimate vendor, changing payment details, or submitting invoices for goods and services never delivered.
Globally, companies have lost billions of dollars to such schemes. One of the most notable examples is the 2014–2016 case involving Facebook and Google, where a fraudster created fake invoices and tricked both companies into paying over $100 million to accounts posing as a legitimate supplier.
Locally, many organisations have experienced similar threats—fraudulent invoices slipping through weak approval systems, vendors being impersonated through email spoofing, or staff colluding with external actors to approve inflated bills.
Without strong verification and approval structures, finance teams become vulnerable to simple but devastating tricks.
Accounts Payable Processes: A High-Risk Target
The Accounts Payable department is a frequent entry point for fraud because it handles large volumes of invoices, payments, and vendor interactions. Common AP-related fraud schemes include:
- Duplicate payments—criminals take advantage of poorly controlled systems to submit the same invoice multiple times.
- Vendor impersonation—fraudsters send emails requesting a “quick update” of bank account details.
- Internal collusion—staff collaborate with external vendors to fabricate invoices or inflate service costs.
- Payment diversion—changing payment instructions after approvals.
In 2023, a large energy company in Europe lost £2.1 million after fraudsters hacked email threads and replaced vendor banking details with their own. The payment was processed because no secondary verification existed.
The lesson is clear: even the most well-established companies are vulnerable if controls are not continuously strengthened.

How Fraud Threatens the Accounting and Finance Industry
Fraud affects more than financial statements. It creates:
- Operational disruptions — delayed payments, reconciliations, and audits
- Financial losses — often unrecoverable
- Reputational damage — loss of client and stakeholder trust
- Regulatory consequences — penalties for inadequate controls
- Increased audit and compliance costs
For consulting and accounting firms, the stakes are even higher. Clients rely on firms for accuracy, credibility, and expert oversight. A single breach could compromise that trust.
Strengthening Defenses: What Businesses Must Do
To protect the financial ecosystem, organisations must adopt stronger preventive measures, including:
- Robust vendor verification — validating payment detail changes through phone calls or face-to-face checks.
- Segregation of duties — ensuring no single individual controls invoice creation, approval, and payment.
- Automated AP systems — reducing manual work that exposes organisations to human error and manipulation.
- Regular training — educating staff to identify phishing emails, spoofing attempts, and payment diversion tactics.
- Continuous monitoring — reviewing unusual trends such as sudden vendor changes, inflated invoices, or repetitive payments.
- Independent audits — inviting third-party checks to identify loopholes and enforce compliance.
A Call to Action for Financial Leaders
As we observe International Fraud Awareness Week 2025, Bizexcel Partners encourages businesses to strengthen their internal controls, invest in modern accounting systems, and foster a culture of vigilance.
Fraud is evolving—and so must our defenses. The financial and accounting sector carries the responsibility of safeguarding organisational assets, ensuring transparency, and upholding trust. By tightening processes and staying alert, organisations can protect themselves and contribute to a safer, more resilient business environment.
