Who I Am and Why You Should Listen

I’ve been in public accounting since 1990. I founded my own firm in 1993, merged it in 2001 to form Howard, Howard and Hodges, and grew it from three people to 50 staff across four locations and multiple states. Our firm was named PASBA Firm of the Year.

I’ve made this exact mistake and paid for it. I promoted my best senior — a genuinely gifted technical accountant — into a manager role because the work she produced was flawless, and I assumed flawless work meant she’d run a team well. She didn’t, at first, and it wasn’t her fault. I’d handed her a completely different job with no preparation: suddenly she had to review instead of do, coach instead of fix, delegate instead of control, and have hard conversations she’d never been taught to have. She nearly quit, and I nearly lost one of the best people I ever hired — to a promotion. Since 2020 I’ve built a development platform that more than a thousand professionals across dozens of PASBA member firms have moved through, and it taught me that the manager transition is the most under-supported, highest-stakes leap in a firm. This article is what I wish I’d known before that promotion.

The Promotion Mistake CPA Firms Keep Making

The pattern is nearly universal in accounting firms: the best preparer becomes the tax manager. The strongest bookkeeper becomes the supervisor. The most reliable senior accountant becomes the one running the team. The logic feels airtight — they’re the best at the work, so they should lead the work.

Except the data says that logic is backwards. The most rigorous study ever done on this — Benson, Li, and Shue’s analysis of 53,035 workers across 214 companies, of whom 1,531 were promoted to management — found the best individual performers were more likely to be promoted and more likely to perform poorly as managers, confirming the Peter Principle empirically. Worse, the researchers found that the performance of a new manager’s subordinates declined relatively more when the role was filled by someone who had been a strong individual performer. The star doesn’t just struggle — the team struggles under them.

This isn’t a knock on your best people. It’s a knock on the assumption that technical excellence predicts management ability. As Gallup’s 2026 research bluntly put it, 65% of managers were promoted for the wrong reasons, producing an 11-point engagement gap — supervisors promoted for frontline performance show 31% engagement versus 42% for those promoted for supervisory capability.

You don’t promote your best staff into failure because they’re not good enough. You promote them into failure because you selected them for one skill bundle and dropped them into a role that requires a completely different one — with no bridge between the two.

Doing the Work and Managing the Work Are Not the Same Job

The root of the problem is a category error: treating “senior accountant” and “manager” as adjacent rungs on one ladder, when they’re actually two different jobs that happen to share a profession. The academic research names it precisely — selection on one skill bundle (individual production) places workers into roles where that bundle transfers poorly (people management).

Look at what actually changes the day someone becomes a manager:

Every row is a genuine skill, and not one of them is taught by being excellent at the left column. A brilliant preparer has spent years mastering the left side — which is exactly why the right side feels so foreign and frustrating when they’re suddenly responsible for it. Execution is about accuracy and completion. Management is about review, delegation, judgment, communication, and accountability for others. Different jobs.

The Signs Someone Was Promoted Before They Were Ready

A manager who was promoted without preparation shows a recognizable set of symptoms — and crucially, these are signs of a missing skill, not a bad hire. Watch for:

• They redo staff work instead of coaching it. The fastest tell. A new manager who can’t yet coach simply takes the work back and fixes it themselves, because that’s the skill they have. The staffer learns nothing and the manager drowns.
• They avoid difficult client conversations. Technical mastery never required hard conversations; management does. An unprepared manager dodges the awkward call about scope, fees, or a missed deadline — and the problem festers.
• They struggle to delegate. Having been rewarded their whole career for personally doing excellent work, they can’t let go of it — so they hoard tasks, overload themselves, and bottleneck the team.
• They become the bottleneck. Every question, every review, every decision routes through them because they haven’t built the systems or the trust to distribute it. (This is the manager-bandwidth trap — see why your managers aren’t too busy to train.)
• They burn out. Doing their old job and their new one at once, because they never learned to actually do the new one, is unsustainable — and it’s how firms lose a great technician and fail to gain a great manager in a single move.

If you’re seeing these in a recently promoted person, the answer isn’t to question the promotion. It’s to provide the development that should have come with it.

Why Shadowing Doesn’t Prepare People for Management

The default firm response to “we need to develop this person into a manager” is the same default that fails everywhere else: have them shadow an existing manager and absorb it. It doesn’t work, for a reason specific to management.

Watching a manager does not teach you how to think like one. Management is largely invisible — the real work is the judgment happening inside the manager’s head: why they prioritized this job over that one, how they decided to coach rather than correct, what they noticed in the client’s tone that changed their approach. A shadower sees the surface behavior but not the reasoning that produced it, so they learn to imitate actions without understanding the judgment underneath. And when the new manager faces a situation that doesn’t match what they watched — which is most situations, because management is endlessly variable — they have no framework to fall back on.

Management readiness, like every other real capability, is built through practice with feedback, not observation. Future managers need scenarios where they make the call — review this work, handle this client, coach this struggling staffer — get feedback on their judgment, and build the decision-making muscle before the stakes are real. (The same reason shadowing fails for technical training — see structured training vs. shadowing.)

What Future Managers Need to Learn Before Promotion

The skills that make a manager effective are specific, nameable, and learnable — which means they can be developed before the promotion rather than discovered painfully after it. The core curriculum:

This is the bridge from technician to leader — and it maps to a deliberate development progression. Technical execution builds the foundation (the work that earns the promotion). Advisory judgment and client-facing confidence make someone effective with clients and complex decisions. Leadership and ownership thinking prepare them to actually run a team and, eventually, help own the firm. Each layer is built before it’s needed, not improvised after. (The judgment layer is covered in developing advisory skills in accountants; the ownership layer connects to succession planning for partners.)

What Changes When You Prepare Managers Before Promoting Them

The firms that develop managers before the title — rather than promoting on technical merit and hoping — see the difference compound across the whole team. The contrast is stark:

The promotion stops being a gamble with one of your best people and becomes a planned transition you’ve prepared them to win.

Frequently Asked Questions

Why do great accountants struggle after being promoted to manager?

Because technical excellence and management ability are different skill sets, and being promoted for the first doesn’t supply the second. A strong senior accountant has mastered doing the work — accuracy, speed, technical correctness — but a manager must review others’ work, coach staff, delegate, manage clients, protect team deadlines, and make judgment calls under pressure, none of which their technical career taught them. This is the Peter Principle, confirmed by a study of 53,000+ workers showing the best individual performers were more likely to be promoted and more likely to fail as managers, with their teams’ performance declining. The struggle isn’t a sign the person was a bad choice; it’s a sign the firm promoted them without building the distinct skills management requires.

What is the Peter Principle in accounting firms?

The Peter Principle holds that organizations promote people based on performance in their current role until they reach a role they can’t perform well. In accounting firms it shows up as promoting the best preparer to tax manager or the strongest bookkeeper to supervisor on the assumption that technical excellence predicts management ability. Research confirms it does not: the best individual performers are both more likely to be promoted and more likely to underperform as managers, and Gallup found 65% of managers were promoted for the wrong reasons, producing an 11-point engagement gap between those promoted for supervisory capability and those promoted for frontline performance. The fix is to develop management readiness before promotion rather than selecting on technical skill and hoping it transfers.

What skills do accounting managers need beyond technical ability?

Seven core skills that technical work never builds: review judgment (evaluating others’ work, a distinct skill from doing your own); staff coaching (developing people instead of redoing their work); client communication (hard conversations and relationship ownership); delegation (letting go of work you excel at); escalation judgment (knowing what to handle, escalate, or decide alone); workflow and project ownership (protecting team-wide deadlines, not just personal output); and basic firm economics (realization, utilization, and the business impact of decisions). These are learnable and should be developed before promotion through structured practice and feedback, not discovered through trial and error after the title is granted, which is how firms produce frustrated managers and declining teams.

How do you train someone to become an accounting manager?

Through structured development of management-specific skills before the promotion, built via practice and feedback rather than shadowing. Shadowing fails because management is largely invisible — the real work is the judgment inside the manager’s head, which a watcher can’t see — so future managers instead need scenarios where they make the actual calls (review this work, handle this client situation, coach this struggling staffer), receive feedback on their judgment, and build decision-making capability before the stakes are real. The progression moves from technical execution (the foundation that earns promotion) to advisory judgment and client confidence, to leadership and ownership thinking. Developing these layers deliberately, before the title, turns promotion from a gamble into a prepared transition.

Why shouldn’t you promote your best technical performer to manager?

You can and often should — but not without preparing them, because technical skill doesn’t predict management skill and promoting on it alone reliably backfires. Research shows the best individual performers are more likely to fail as managers and that their teams’ performance tends to decline, because the firm selected for individual production and dropped the person into a people-management role where that skill transfers poorly. The risk is losing a great technician while failing to gain a great manager in one move. The answer isn’t to hold your best people back; it’s to develop their management readiness (review judgment, coaching, delegation, client communication) before granting the title, so the promotion succeeds instead of souring.

How do you know if a manager was promoted too soon?

Watch for five warning signs, each indicating a missing management skill rather than a bad person: they redo staff work instead of coaching it (no coaching skill yet); they avoid difficult client conversations (untrained in hard communication); they struggle to delegate (can’t let go of work they excel at); they become the bottleneck through which every decision and review must pass (haven’t built systems or trust to distribute it); and they burn out from doing their old job and new job simultaneously because they never learned to actually do the new one. These are correctable through targeted management development; the appropriate response is to provide the skill-building that should have accompanied the promotion, not to second-guess the person’s potential.

The Bottom Line

Promoting your best technical person into a management role and expecting them to figure it out is one of the most common and most expensive mistakes a firm makes — and the research is unambiguous that it backfires more often than it works. The best individual performers are the most likely to be promoted and among the most likely to struggle as managers, taking their team’s performance down with them. Not because they’re not talented, but because you handed them a different job and skipped the part where you prepared them for it.

The answer is simple to state: let technical excellence earn the promotion, but let structured development make the promotion succeed. Build review judgment, coaching, delegation, and client confidence before the title, through real practice and feedback rather than shadowing and hope. Do that, and you stop sacrificing your best people on the altar of their own success — and start turning them into the managers who multiply your firm instead of bottlenecking it.

Your best staff aren’t failing after promotion because they’re not good enough. They’re failing because “great at the work” and “great at leading the work” are different skills — and you only taught them the first one.

Before you promote another technically strong person into a manager role — make sure they’re actually ready to manage.
