The private equity wave reshaping the accounting profession has generated plenty of headlines about deal volume, valuation multiples, and the firms positioning themselves as platforms. What those headlines rarely address is the talent problem hiding in plain sight: most consolidating firms are acquiring client books and revenue, but few are acquiring the thing that sustains growth after the deal closes — partners who know how to develop new business.
This is not a problem the transaction created. It is a problem the transaction accelerated. And for managing partners navigating the new landscape of accounting firm consolidation, it may be the most consequential challenge on the agenda.
The leadership gap is straightforward to describe and surprisingly difficult to solve. The generation of partners who built their client relationships through decades of deliberate, face-to-face business development is retiring. Their replacements — talented, technically excellent, client-service-oriented professionals — were trained to deliver, not develop. Technical mastery was rewarded. Business development was tolerated as a personality trait that some people happened to have, not as a learnable, coachable, measurable set of skills.
The result is a bench that can serve clients at a high level but struggles to grow the firm organically. When consolidation enters the picture, that gap compounds quickly. Acquired firms often carry the same deficiency. The acquiring firm assumes that integration will solve the growth problem — that scale will create momentum. It rarely does. Scale changes the infrastructure; it does not change people.
For PE-backed platforms in particular, the stakes are high. Revenue growth is not optional; it is the thesis. Sponsors underwriting acquisitions at current multiples need organic growth to validate the model. A firm with an aging rainmaker cohort and an underdeveloped next generation is a risk that does not show up on the due diligence checklist but shows up on the income statement.
This question deserves a candid answer, and the candid answer is that most of the partners who should be doing the training never had a training program themselves. They built their books through relationships that developed over years — at civic organizations, at the club, through referrals, through quiet persistence in communities where their names became synonymous with trust. There was no playbook because they did not follow one. They figured it out, and they assumed the next generation would too.
The billable hour model reinforced this assumption by penalizing the alternative. Time spent mentoring a senior manager on business development was time not billed. In a model built around utilization rates, coaching was a cost, not an investment. The incentive structure sent a clear message, even when firm leadership intended to send a different one.
There is also a distinction that deserves more attention than it typically receives: technical mentorship and leadership development are not the same thing. A managing partner who is an extraordinary tax technician may be an excellent mentor for developing deep technical skills. That same partner may have no language for teaching someone how to identify an opportunity in a client conversation, how to handle a referral relationship, or how to position the firm's broader capabilities without it feeling like a sales pitch. These are different disciplines, and conflating them has left a generation of firm leadership without the tools to develop the one their firms need most.
Here is where a great deal of conventional thinking goes wrong: business development is not one thing, and it is not the exclusive territory of the extrovert with the big personality and the endless contact list.
Business development is everyone's responsibility. The form it takes depends on the individual.
The classic rainmaker — the partner who, as Dale Carnegie put it, knows how to win friends and influence people — is one archetype. That person is magnetic, comfortable in any room, effortlessly connects with prospective clients, and builds trust quickly at a personal level. Firms need people like this. They are valuable and relatively rare.
They are also not the only model that works.
The deeply technical partner who guides clients through a complex transaction, an IRS examination, or a business restructuring with calm authority is also developing business. When clients feel that their advisor genuinely understands their situation and is invested in the outcome, they do not leave. They refer. They bring more of their business to the table. That is business development, even if it never looks like a sales call.
The relationship-oriented partner who lights up every room, remembers every client's spouse's name and their children's schools, and shows up consistently at the right community events is also developing business. Different style, same outcome.
The point is not to identify the rainmakers and leave everyone else on the bench. The point is to understand that every partner in your firm is already in client-facing, relationship-bearing interactions every day. The question is whether those interactions are intentional, whether there is a framework for making the most of them, and whether the firm is investing in helping partners develop their version of the growth role.
It should not — and this is an important distinction for firms that have invested in business development staff or are considering doing so.
A dedicated BD function is a valuable asset. BD professionals open doors, manage pipelines, research prospects, coordinate proposals, and support the overall growth process in ways that free partners to spend their time where it matters most. That investment pays off.
What it does not do is replace the partner. Clients hire firms, but they stay because of people. The relationship — the trust, the familiarity, the confidence that comes from working with someone who genuinely knows your business and your goals — lives with the partner. No BD team replicates that. The most effective firms understand that the BD function and the partner work in concert: the function provides the infrastructure, and the partner provides the relationship.
When partners assume that a business development team removes them from the growth equation, the firm underperforms. The partner remains the central player. The BD function makes that player more effective.
Consolidation creates a specific set of challenges that go beyond the general problem of leadership development.
Merged firms carry different cultures around business development. Some acquired firms have a strong BD culture; others have none. Integration planning tends to focus on systems, processes, client transitions, and staff retention. People development — specifically, the behaviors and mindsets that drive organic growth — is rarely addressed in the integration plan and almost never measured during the first year post-close.
The assumption is that culture will sort itself out. Sometimes it does. More often, the acquired firm's partners adapt to the acquiring firm's operational model without anyone paying attention to whether they are equipped to grow business in the new, larger environment. A partner who was a standout performer in a 20-person regional firm may have built a client book through deeply personal relationships in a tight community. In a 200-person national platform, those same instincts may not translate without intentional support.
There is also the cross-selling opportunity that consolidation is supposed to unlock but rarely does organically. Clients of acquired firms represent a significant opportunity to introduce broader services — tax, advisory, transaction support, specialized industry capabilities. Partners who have not been developed to think and act like growth partners will not pursue that opportunity systematically. It requires skills, confidence, and a framework. None of those appear automatically on the day a deal closes.
Firms that grow after the close are the ones that treat people development as a strategic priority, not an HR function. They assess BD capability as part of integration planning. They identify the partners on both sides of the transaction who have growth potential, and they invest in developing it deliberately.
The honest answer is earlier than feels necessary, which means earlier than most firms start.
Consider the math. If a managing partner is 55 today, the partners who will carry the firm's growth mandate over the next decade are somewhere between 38 and 48 years old right now. They are experienced. They are trusted by clients. They have the technical foundation. What many of them lack is the intentional development, the coaching, and the accountability structure that would turn them into genuine growth leaders.
Building a true growth partner from a talented technical professional takes time. Two to four years of structured, consistent, observed development is a realistic timeline for meaningful transformation. That is not a criticism of the individuals; it is simply the reality of building a complex, relationship-driven skill set while also serving clients at a high level.
The cost of waiting is not abstract. Every year of delay is a year closer to the transition point — the retirement, the succession event, the platform integration — without the bench in place to absorb it. The firms that arrive at those moments with a developed next generation did not get lucky. They started earlier than felt urgent.
It is not a seminar. It is not a personality assessment tool or a LinkedIn masterclass. It is a structured, sustained, observed process with real accountability built in.
It starts with honest assessment — identifying which partners have genuine growth potential and what their natural style looks like. Not every senior manager or income partner will become a growth partner, and the wrong development investment is expensive in time, money, and morale. The right candidates are not always the most obvious ones.
It continues with a clear definition of what growth means in the firm's specific context. Origination — developing new client relationships from scratch — requires a different skill set than cross-selling additional services to existing clients, which requires different skills again from deepening and retaining the most valuable existing relationships. Each pathway needs its own development approach.
It includes the things that make development real rather than aspirational: a pipeline the partner owns, opportunities that are tracked and reviewed, conversations that are coached rather than just observed, and feedback that is honest rather than comfortable. This level of rigor is not punitive; it is respectful of the partner's time and the firm's investment.
And it connects compensation and advancement to measurable BD outcomes. Without this piece, the signal that partners receive — regardless of what firm leadership says in meetings — is that business development is optional. The compensation structure tells the truth about what the firm values. If growth is not reflected in it, the development program will not hold.
Every managing partner who has built something worth having will eventually face a version of the same question: What kind of firm am I leaving behind?
A firm that grew because it acquired revenue is a different thing from a firm that grows because it developed the people inside it. Both can be successful. Only one compounds over time.
The next generation of growth partners is not going to develop itself. The window to build them is open now, and it will not stay open indefinitely. If your firm is wrestling with how to close this gap — whether in the context of consolidation, succession, or simply sustainable organic growth — it may be time to take a closer look at how you are developing the partners who will carry your growth forward.
That is a conversation worth having.
