How Top CPA & Accounting Firms Bill Fewer Hours and Earn More

For most of the profession’s history, the hourly rate was the only number that mattered. It determined how partners measured productivity, how staff were evaluated, how clients were billed, and how firms benchmarked themselves against peers. That model is now eroding, and the evidence is hiding in plain sight. 

In 2024 report data, hourly billing still accounted for 65.5% of firm revenue, with value-based pricing at 30.7%. The headline rate looked stable. But the more revealing story shows up in the structural data: partner billing rates are climbing across every firm segment, while the number of hours those partners are actually billing has dropped sharply. The “rate” is rising, but the “hour” is doing less and less of the work. That is not a pricing trend. That is a business model transition. 

The Default Model Is Losing Ground 

Hourly billing was never built for what modern firms actually deliver. It rewards activity over outcome, penalizes efficiency, and creates incentives that point in the wrong direction. As firms move toward advisory, recurring services, and embedded technology, the structural mismatch becomes harder to ignore. 

In the 2024 baseline, value-based pricing was already nearly a third of the average firm’s revenue mix — and that share was concentrated heavily at the upper end of the market, where larger firms have led the transition. By 2025, the indirect signals across every billing metric confirm the trajectory is accelerating. 

The Movement Is Visible Across Every Segment

The 2024 to 2025 data shows rate increases across every firm size, but the pace is uneven. The smallest and largest firms moved fastest, while the Large segment ($50–150M) saw the smallest move at +4.8%.

Firm Size	2024 Rate	2025 Rate	YoY Change
Ultra-Small (<$2M)	$321	$371	+15.6%
Small ($2–5M)	$348	$373	+7.2%
Early-Mid ($5–15M)	$379	$410	+8.2%
Mid-Size ($15–30M)	$422	$466	+10.4%
Regional ($30–50M)	$471	$500	+6.2%
Large ($50–150M)	$545	$571	+4.8%
Top (>$150M)	$622	$699	+12.4%

The partner-to-staff billing ratio widened from 2.83x to 3.08x across the profession, reflecting how the value of partner expertise is being repriced relative to execution work. This is not a top-tier phenomenon. It is happening at every level.

The Most Telling Evidence Is in the Hours Worked 

The clearest signal isn’t a pricing survey. It is how partner time is being deployed. 

At top-tier firms (>$150M), equity partner charge hours dropped from 1,128 to 877 in a single year — a 22% decline. Non-equity partners at the same firms fell from 1,154 to 920 hours (–20%). At the same time, equity partner billing rates at those firms rose 12.4%, from $622 to $699. The same firms reported overall realization improving from 81.2% to 84.4% — a 3.2 percentage point gain that the data attributes to effective value pricing implementation. 

Top-tier partners are billing 22% fewer hours and charging 12% more per hour. 

The math only works if hourly time is no longer the primary unit of value being sold. 

Rates went up. Hours went down. Realization improved. Hourly billing alone cannot produce that combination. 

What’s Replacing It 

The replacement isn’t a single model. It is a portfolio of pricing structures that better match the value being delivered: 

Model	Where It’s Showing Up	Why It’s Winning
Fixed-fee engagements	Compliance work with predictable scope	Reduces realization leakage from scope creep
Retainer / subscription	Advisory, CAS, ongoing client services	Smooths revenue, deepens client relationships
Value-based pricing	High-complexity advisory and consulting	Captures outcome value; supports 95%+ realization
Hybrid structures	Mid-complexity work with variable inputs	Combines predictability with flexibility

The realization pattern supports this directly: traditional compliance services average 85–90% realization, while advisory and consulting services priced on value can reach 95%+. The pricing model is not just a billing convention. It is the single largest factor in whether a firm collects what it bills.

What This Means for Firm Leaders 

The question is no longer whether hourly billing will fade. The data already shows it fading. The question is how quickly your firm is repositioning, and whether the structures supporting that transition — pricing, engagement scoping, partner time allocation, client communication — are evolving at the same pace. 

Many firms continue to track billing performance through the lens of hours billed and standard hourly rates. The more revealing metrics are realization by service line, revenue per chargeable hour, and the proportion of revenue earned through non-hourly structures.

These patterns vary significantly by firm size, service mix, and market context. Without a clear benchmark, it can be difficult to determine whether your firm is leading or trailing the broader profession. Understanding these dynamics in greater depth can offer a meaningful perspective when evaluating pricing strategy, engagement design, and long-term financial positioning.
