Many companies expect their auditors to detect fraud, and yet most auditors (external and internal) do not use procedures or tests that will achieve this objective. This is because fraud, by its very nature, is often off-record or disguised within records. Most auditors, who traditionally receive little or no training in fraud detection, will look at what is on-record and rarely question the authenticity, validity or reasonableness of source documents. Therefore a fraud involving false purchase invoices, supported by false ancillary records, is unlikely to be detected by traditional audit techniques.

Haymarket carries out fraud detection reviews using proprietary Fraud Profile Auditing techniques, which will detect fraud where it was previously unsuspected. It uses automated tests, which quickly identify the small number of suspicious transactions that merit more detailed examination. Further tests will go beneath the surface and probe the authenticity of source documents. Haymarket's Forensic Accountants use specialised, proprietary software tools to review, analyse and cross-match information on clients' accounts ledgers and other records against Haymarket's specialised databases, to quickly pinpoint the clues to fraudulent activity.

Fraud Detection Reviews can be carried out covertly or overtly. They are relatively inexpensive and often produce results that can be spectacular in terms of fraud detection.
