If you mean post-merger/post-acquisition audit work—checking whether the acquired company's books, purchase accounting, working capital, controls, and deal assumptions hold up after closing—I’d shortlist these firms in/around Orange County:
For a true post-merger integration audit, I'd start with Avant Advisory Group because it is unusual to find a firm that explicitly combines post-merger integration implementation with forensic accounting. For a larger, more formal engagement—especially involving PE ownership, multiple entities, or potential litigation—Baker Tilly would be my next call.
When interviewing them, I'd ask specifically whether they've performed post-close purchase-price/working-capital true-ups, purchase accounting validation, revenue recognition testing, intercompany reconciliation, fraud/related-party transaction testing, internal-control integration, and synergy/EBITDA validation. Those are much more relevant than simply asking whether they "do forensic accounting."
If you tell me the size of the acquisition, industry, and whether you're the buyer or seller, I can narrow this to the 3 best-fit firms and compare their likely strengths, size, and local contacts.

When seeking a forensic accounting firm for post-merger integration (PMI) audits—typically triggered by purchase price adjustments, earn-out disputes, or suspected financial misrepresentations—you generally look at elite global consulting practices, dedicated risk firms, or specialized national practices.
Top-tier options equipped for post-acquisition and PMI audits include:
If you'd like to narrow this down, please let me know:
- **Urish Popeck & Co., LLC** - Four Gateway Center, 444 Liberty Ave #1400, Pittsburgh, PA 15222, United States - **HBK Valuation Litigation and Forensics** - 310 Grant St Ste 1550, Pittsburgh, PA 15219, United States - **ParenteBeard LLC** - 20 Stanwix St, Ste 800, Pittsburgh, PA 15222
If you’re looking for a forensic accounting firm with post-merger integration audit experience, I’d focus on firms that can do more than fraud investigations—specifically those with M&A advisory, purchase accounting, financial controls reviews, integration testing, ERP/reporting alignment, and post-close dispute analysis capabilities.
Here are several firms worth considering:
If you are looking for a Pittsburgh-area firm, some local options with forensic accounting capabilities include:
When screening firms, I’d ask:
If you share the deal size (e.g., <$50M, $50M–$1B, enterprise), industry, and location, I can narrow this to the best-fit firms.

When looking for a forensic accounting firm that specializes in post-merger integration (PMI) audits, post-acquisition disputes, and purchase price adjustments, you generally want to target specialized global consultancies or the dedicated forensic and dispute services arms of major accounting networks.

To help narrow down the right firm or practice group, could you share:

Yes. For forensic accounting specifically tied to post-merger integration, I’d focus on firms that combine forensic accounting with M&A transaction advisory—not just traditional auditors.
If I were sending out an RFP, I'd probably invite FTI Consulting, Alvarez & Marsal, EY, and WilliamsMarston. They cover slightly different needs:
| Firm | Best fit |
|---|---|
| FTI | Forensic investigation + complex integration |
| A&M | Hands-on PMI + accounting/operational remediation |
| EY | Big Four scale + transaction forensics |
| WilliamsMarston | Specialized accounting + PMI execution |
If by “post-merger integration audit” you mean auditing whether the acquired company's books, controls, accounting policies, purchase accounting, working capital, and financial reporting were properly integrated after closing, rather than investigating fraud, I can narrow this to 3–5 firms that are particularly strong in that exact engagement—and compare their likely fit, size, and DC/Northern Virginia presence.

Yes. If by “post-merger integration audits” you mean an independent review of the acquired company after closing—checking accounting integration, controls, purchase accounting, working capital/earn-outs, financial reporting, and potential discrepancies—I’d focus on firms with both forensic accounting and M&A transaction-advisory capabilities.
My initial shortlist would be LCG Advisors for a Tampa-area/middle-market engagement, and KPMG/EY/Baker Tilly if this is a large or complex transaction. If the objective is specifically to find accounting irregularities or seller misrepresentations, I'd put GFFA, MDD, or CRA higher on the list.
If you tell me (1) your location, (2) approximate transaction size, and (3) whether you're the buyer, seller, PE sponsor, or board, I can narrow this to 3–5 firms that are genuinely specialized in your type of post-merger audit, including relevant partners and contact information.
