Leadership succession is now the top challenge for accounting firms, with partner retirements accelerating and over half of professionals considering leaving their current roles. Firms that invest in structured, long-term leadership development see significant gains in retention and performance. However, strategic external hiring remains essential for specialist skills and growth. The most successful firms balance internal development with targeted hiring, ensuring strong integration and transparent career paths. This approach not only secures succession but also boosts firm valuation and market reputation¹⁰. Talent strategy is now the ultimate differentiator for sustainable success.
If you’re leading a firm today, you know the talent landscape feels like it’s shifting under your feet. Here are five things every partner should keep front of mind:
Take a look at what is happening across the profession. In just the last two years, over 360 equity partners retired from the firms Inside Public Accounting surveyed². The pace is picking up, and the real challenge is the gap between those leaving and those ready to step up. ICAEW found that almost half of mid-tier firms put succession planning at the top of their talent worries, and another big chunk are concerned about future-proofing skills¹.
It’s not just about who’s leaving, because the best people are always on someone else’s radar. ACCA’s latest survey says over half of professional accountants expect their next move to be outside their current firm³. That means you are not just competing with other practices, you are up against industry, consulting, and anyone who offers a clearer path forward³.
Here’s the good news: when you invest in your people, it works. The Firm Catalyst found that firms with solid leadership programs saw productivity rise by 30% and turnover drop by a whopping 77%⁴. Select Advisors Institute tells the story of a mid-sized firm that built a leadership program around mentorship and emotional intelligence and after a year, employee satisfaction was up 40% and client retention rose 25%⁵.
The Growth Partnership tracked what actually changed for people in leadership training: strategic thinking, decision-making, and communication all improved by 28%⁶. When you develop people systematically, you don’t just keep them, you help them thrive.
After looking at what works, some patterns are clear:
Internal development is critical, but sometimes you need to look outside. ICAEW’s research shows that nearly half of firms made acquisitions last year to get capabilities they couldn’t build fast enough in-house¹. External hiring makes sense when you need
But be careful, lateral hires fail more often than anyone likes to admit usually because of culture clash, weak onboarding, or poor communication about why you’re hiring externally¹. Make sure you’re clear, supportive, and intentional.
The best firms don’t pick one approach over the other, they regularly review their pipeline, map out upcoming retirements, and honestly assess who’s ready to step up². They’re transparent about what they need, promote people who are 70–80% ready and help them grow, and only hire externally when there’s a real gap⁴.
When you do hire from outside, make integration a priority. Structured onboarding, mentorship, and getting new people involved in firm-wide initiatives early makes all the difference¹.
Your leadership pipeline isn’t just about continuity, it’s also about value. Investors and PE firms scrutinise how you develop and keep leaders. ICAEW reports that a quarter of mid-tier firms are already PE-backed, and another quarter are likely to pursue investment soon¹. Among independents, 93% have had interest from PE in the last three years¹.
When we speak with candidates, it’s clear they are paying close attention to firm culture. ACCA’s 2024 survey reinforces what we hear every day: 73% of professionals are actively looking for employers who demonstrate a strong commitment to diversity, inclusion, and transparent career progression¹⁰. Candidates want to see that firms genuinely invest in their people and provide clear opportunities to grow.
The firms that will win in the next decade aren’t necessarily the biggest, they’re the ones who treat leadership development as a true strategy. The most valuable firms invest in people, are transparent about career paths, and balance systematic internal development with strategic external hiring.
Three things always matter:
Talent is now both the ultimate constraint and the biggest differentiator. The partners who focus on people development will lead in value, succession, and long-term success.
