Overview
In this Procurement Invoice Fraud Investigation Case Study – Corporate Investigations UK, I led a detailed enquiry into suspected invoice manipulation within a mid-sized company. With over 15 years of investigative experience, I directed a targeted strategy that secured Evidence to a Court Standard while maintaining full discretion.
The Client’s Concern
The client noticed irregularities in supplier payments, which appeared inflated over several months. Although internal checks raised concerns, the finance team could not confirm deliberate fraud. Therefore, they instructed Corporate Investigations to establish the facts and protect the business from further losses.
Investigation Strategy
Firstly, we reviewed procurement processes and analysed historic invoice data to identify unusual trends. Next, we cross-referenced supplier records against payment schedules, which revealed inconsistencies. Additionally, we conducted covert enquiries into supplier legitimacy and employee activity.
Moreover, our team carried out focused surveillance and background checks on key individuals linked to the procurement chain. As members of the Institute of Professional Investigators (IPI), we ensured all methods complied fully with UK law and produced Evidence to a Court Standard.
Key Findings
During the investigation, we uncovered a fraudulent scheme involving a procurement manager and a fake supplier account. Specifically, the employee had created false invoices and approved payments to an account under their control.
Furthermore, financial tracing confirmed that funds had been diverted over a sustained period. In addition, behavioural surveillance supported the connection between the employee and the fraudulent activity.
Consequently, we compiled a comprehensive evidential report that clearly outlined the fraud, supported by documentation suitable for legal proceedings.
Outcome
Following our findings, the client immediately suspended the employee and reported the matter to the authorities. As a result, legal proceedings were initiated with strong supporting evidence.
Importantly, the client recovered a portion of the financial losses and strengthened internal procurement controls. Therefore, the risk of similar fraud has been reduced significantly.
