Private equity has spent the last decade buying up doctor’s offices, veterinary clinics, and auto repair shops. Now it has set its sights on something less glamorous but arguably more lucrative: regional accounting firms.
The Deal Flow Accelerating Across the Profession
Over the past few years, a quiet but rapid consolidation wave has moved through the accounting industry. Private equity-backed platforms – often called “PE-backed rollups” – are acquiring regional CPA firms, folding them into larger networks, and promising partners a liquidity event that the traditional partnership model rarely offers. What started as a handful of deals is now something closer to a structural shift in how mid-market accounting services are owned and operated.
The appeal for PE buyers is straightforward. Accounting firms generate sticky, recurring revenue. Audit and tax clients rarely switch providers. Compliance-driven demand – from tax filings to financial statement reviews – does not disappear during economic downturns. For a private equity fund looking to deploy capital into a defensive, cash-generating business, a well-run regional firm with 50 to 200 staff and a loyal book of business is close to an ideal acquisition target.
On the firm side, the logic is equally clear. The traditional CPA partnership model has a succession problem. Older partners who built their practices over decades face a narrowing pool of younger CPAs willing to buy in at elevated valuations. The pipeline of future partners has shrunk as the profession struggles to attract new talent – accounting graduate enrollment has declined for several consecutive years, and the CPA exam pass rate remains low. Selling to a PE-backed platform offers founding partners real cash, not just a promise of gradual buyout payments from the next generation.
The platforms doing the buying are not household names, but their backers often are. Several large PE firms have funded dedicated accounting rollup vehicles, each targeting firms in the $5 million to $50 million revenue range – large enough to have stable client bases, small enough to still be acquirable at reasonable multiples. Once inside the platform, acquired firms typically retain their local brand, their managing partners, and their client relationships, at least in the early years.
What Changes Inside the Firm – and What Doesn’t
The pitch to partners is that little will change operationally. In practice, the pressure to standardize, centralize, and grow kicks in fairly quickly. Platforms consolidate back-office functions – payroll, HR, IT infrastructure, billing systems – across all member firms to capture margin. This makes sense on paper. A network of twenty firms should not be running twenty separate general ledgers or negotiating twenty separate software licensing agreements.
But standardization creates friction in a profession built on relationships and local judgment. A tax partner in a mid-sized Midwestern city has built her practice around knowing her clients personally, showing up at their businesses, and giving advice that reflects an understanding of the local economy. When decisions about staffing levels, billing rates, and service offerings get made at the platform level by operators in a different city, that local character can erode. Some partners who sold into rollups report that the culture changed faster than they expected, particularly around billing pressure and client volume targets.
Compensation structures also shift. In a traditional partnership, profits flow directly to equity partners based on the firm’s performance. Inside a PE-backed network, partners often receive a salary plus some form of equity participation in the platform – ideally positioning them to benefit when the platform eventually sells or goes public. Whether that equity payout materializes depends entirely on the platform’s exit timeline and valuation, neither of which the individual partner controls. It is a different kind of risk than the one they signed up for when they made partner twenty years ago.
Client relationships are the most carefully managed variable. Platforms are well aware that accounting clients are loyal to their specific partners and teams, not to a logo. Aggressive moves to cross-sell services, change engagement teams, or migrate clients onto new technology platforms can accelerate attrition. The more sophisticated rollups move slowly on client-facing changes and focus the early years of ownership on operational efficiency rather than revenue extraction. The less disciplined ones learn the limits of client loyalty the hard way.
Talent retention adds another layer of complexity. Staff accountants and managers who joined a regional firm for its culture and autonomy do not always embrace the transition to a larger, more corporate environment. Turnover in the year following an acquisition can be significant, and in a profession already facing a staffing shortage, losing experienced mid-level staff is a serious operational problem. Some platforms have tried to address this through retention bonuses and equity grants extended to non-partner employees, with mixed results.
Regulatory Uncertainty and the Partnership Ownership Rule
There is a structural wrinkle that makes PE ownership of CPA firms legally more complicated than buying a veterinary chain or a chain of urgent care clinics. Most states require that CPA firms be majority-owned by licensed CPAs. Private equity funds are not staffed by licensed accountants. The workaround – used widely and now under scrutiny – involves creating a two-entity structure: a licensed CPA entity that holds the attest functions (audits, reviews, compilations) and a separate management services organization, or MSO, that handles everything else and is owned by the PE fund. The CPA entity contracts with the MSO for administrative services, and the economic benefits flow upstream to the fund through the management agreement.
This structure has drawn attention from state boards of accountancy and, more recently, from the AICPA, which has signaled concern about whether the arrangement is consistent with the profession’s independence requirements. Auditors are legally required to be independent of their clients – free from financial and organizational pressures that could compromise their judgment. Critics of the PE rollup model argue that when a fund with a five-to-seven-year exit horizon controls the management infrastructure of a CPA firm, the pressure to hit revenue targets can subtly compromise that independence, even if the formal legal structure technically complies with state rules. The same ownership-structure debate has surfaced in other PE-acquired professional services sectors. Whether regulators in accounting move faster or slower than they have elsewhere is an open question – and one that could determine how far this consolidation ultimately goes.
