Postlethwaite & Netterville

What Postlethwaite & Netterville does

Postlethwaite & Netterville (P&N) was a privately held, full-service accounting and business advisory firm headquartered in Baton Rouge, Louisiana. Founded around 1949, P&N operated with 251–500 professionals serving commercial businesses, government organizations, and high-net-worth individuals across the Gulf Coast region. Its service portfolio spanned assurance (audit and SOC examinations), advisory (including risk, strategy and transformation, financial advisory, CFO advisory, government advisory, and workforce solutions), tax (federal, international, private client, state and local), outsourcing (accounting & finance, technology & AI, growth & marketing, HR, and industry-specific operations), and wealth management. The firm did not disclose proprietary technology; its core offering was professional services delivered by credentialed personnel on an engagement-based, fee-for-service model with multi-year contracts and scope-customized pricing.

In 2024, P&N was acquired by EisnerAmper, a Top 20 US accounting and advisory firm with more than 4,500 professionals across US offices and an international network via Allinial Global. Post-acquisition, P&N was rebranded under the EisnerAmper banner and its professionals were folded into the larger platform. The combined entity now delivers a horizontally segmented service architecture covering more than 20 industry verticals (banking, energy, healthcare, government, private equity, blockchain & digital assets, real estate, manufacturing, etc.), with omnichannel distribution through direct professional engagement, a professional directory, and an RFP submission process. Marketing reach is amplified by content (articles, case studies, e-books, webinars, podcasts) distributed via LinkedIn, X, Facebook, YouTube, Instagram, and TikTok.

Revenue mechanics remain quote-based professional services fees tailored to each engagement's scope, complexity, and service mix. Billing cadence runs on multi-year contracts typical of audit, tax compliance, and outsourced finance/IT engagements. The investment-relevant signal is that P&N's standalone economics are now subsumed into EisnerAmper's broader revenue base; the unit retains client continuity and regional density but no longer operates as an independent growth vehicle.
