Client Accounting Services (CAS) continues to gain traction as a strategic growth engine for accounting firms.
New IPA data show that firms generating more than 30% of revenue from CAS are outperforming their peers in several key areas. They report stronger organic growth (10.6% compared to 10.0%), higher realization rates (93.4% versus 90.0%), and greater efficiency in team structure, including higher utilization and support staff ratios.
Despite these advantages, CAS-heavy firms earn significantly less per partner. Net income per partner averages $545,633, compared to $673,985 at traditional firms. This gap reflects the hands-on, relationship-driven nature of CAS work, which often requires more infrastructure and staff investment.
Revenue per full-time equivalent is also lower for CAS firms, highlighting a model that prioritizes client retention and recurring engagement over high-yield project work. Still, CAS firms manage to achieve this without significantly increasing personnel or marketing costs, suggesting a more efficient allocation of resources.
For firms exploring new growth strategies, CAS offers a proven alternative to compliance-heavy business models. The June IPA Insight explores how these firms operate and what tradeoffs they accept in more detail.
