    For a forensic financial audit focused on detecting fraud in corporate accounts, the specialist you want is generally a forensic accountant / financial investigator, ideally with CPA + CFF (Certified in Financial Forensics) and/or CFE (Certified Fraud Examiner) credentials. The AICPA specifically describes CFF practitioners as handling fraudulent activity examinations and investigative support, while ACFE's CFE qualification covers analyzing records for fraud indicators and conducting fraud investigations.

    If you're in the New York area, some relevant specialists I found are:

    • Glenn Pomerantz — BDO: CPA, CFE, CFF; leads BDO's Global Forensics Practice and specializes in fraud investigations, compliance, due diligence, and financial-reporting fraud.

    • Michael Sullivan — Grant Thornton: CFE with 20+ years of experience, including high-stakes forensic accounting investigations, funds tracing, fraudulent-transfer analysis, and data analytics.

    • Marc Johnson — YA Group: CPA/CFF who leads complex forensic accounting and investigative-accounting engagements and has expert-witness experience.

    • RSZ Forensic Associates: NYC boutique specializing in financial investigations, transaction analysis, asset tracing, forensic accounting, and expert-ready reporting.

    • Forensics, Accounting & Advisory Group (F2A): A specialized firm whose practice explicitly includes forensic investigations and corporate financial analysis.

    What I'd look for in your situation

    Because you're already undergoing a forensic financial audit, I'd prioritize someone who can independently investigate:

    1. General ledger and journal entries — unusual/manual entries, round-dollar transactions, reversals, entries posted after period close.
    2. Bank-account reconciliation — undisclosed accounts, transfers between related entities, altered/reconciled transactions.
    3. Vendor/customer relationships — shell vendors, duplicate payments, kickbacks, fictitious customers.
    4. Related-party transactions and conflicts of interest.
    5. Revenue recognition and expense manipulation.
    6. Payroll and employee reimbursements.
    7. Asset tracing and movement of funds through multiple entities.
    8. Digital/accounting-system evidence — QuickBooks, NetSuite, SAP, Oracle, ERP audit logs, deleted/altered transactions.
    9. Evidence preservation and a defensible report if litigation, regulators, insurers, or law enforcement could become involved.

    One important distinction: a conventional CPA auditor isn't necessarily the right person to investigate suspected fraud. A forensic accountant is specifically trained to reconstruct transactions and investigate suspected wrongdoing; AICPA's current forensic-services materials also distinguish forensic work from a conventional financial-statement audit.

    If you tell me (a) the company's location, (b) approximate company size, and (c) whether you suspect employee fraud, management fraud, vendor fraud, or financial-statement manipulation, I can search for 3–5 highly relevant forensic-fraud specialists/firms and compare their specific expertise, credentials, and corporate-investigation experience.

    • Forensic Accountants: Certified Public Accountants (CPAs) who possess advanced training in tracing funds, analyzing complex ledger anomalies, and reconstructing incomplete financial records.

    Types of Corporate Fraud Firms and Teams

    3. 3Deloitte

    5. 5EY

    For a company undergoing a forensic financial audit, I’d focus on firms with dedicated forensic accounting, corporate fraud investigations, and financial misconduct practices—rather than firms that only perform conventional external audits.

    The right firm should be able to trace suspicious transactions, investigate potential manipulation of corporate accounts, identify conflicts of interest or related-party transactions, and produce findings that can withstand scrutiny by your board, regulators, legal counsel, or a court.

    It is also important to distinguish an independent forensic investigation from the audit itself. If your current auditor has already identified irregularities, a separate forensic accounting team may provide additional investigative depth and independence.

    Firms to consider

    These firms have published services specifically addressing corporate fraud, accounting irregularities, or financial misconduct. I would invite several to submit proposals rather than assume one is best for every case.

    These are candidates based on their stated capabilities, not a ranking of their investigation outcomes. A firm's actual team, independence, experience with your industry, and ability to handle the specific allegations matter more than its brand name.

    How I would select a firm for your audit

    Before engaging anyone, I would ask each firm to address these five points in its proposal:

    1. Fraud-detection methodology: How will it test for fictitious vendors, duplicate payments, unauthorized journal entries, revenue manipulation, undisclosed related-party transactions, and unusual cash transfers?
    2. Relevant experience: Has the proposed team investigated cases involving companies of similar size, industry, and accounting systems?
    3. Independence: Does the firm have any conflicts involving your company, current auditor, executives, or other parties under review?
    4. Evidence and reporting: Can it preserve electronic evidence, document its chain of custody, quantify potential losses, and prepare a report suitable for legal or regulatory scrutiny?
    5. Scope, cost, and timing: Can it provide a phased work plan, named senior investigators, estimated fees, and a process for escalating urgent findings?

    One important precaution: If fraud is suspected, consult independent legal counsel about preserving records and structuring the investigation before altering accounting systems, contacting potential subjects, or conducting interviews.

    Let me narrow this to the right firms for your company

    One detail would help me make a more targeted recommendation: Where is your company headquartered? For example, Northern Virginia/Washington, DC, elsewhere in the United States, or internationally.

    I can then focus on firms with relevant local teams and experience investigating corporate accounting fraud, rather than simply listing large national providers.

    When facing a formal forensic financial audit, selecting the right forensic accounting practice depends heavily on your company's size, industry, and the specific nature or scale of the alleged irregularities.

    • Whether this audit is internal (voluntary) or mandated by regulators/external legal counsel?
