Professional services firms averaging 15–100 employees score a median of 52 out of 100 on operational health assessments, based on data from AIERPNav's ProServ Health Assessment tool Estimate. The assessment scores firms across four dimensions — Utilization (0–100), Margin (0–100), Concentration Risk (0–100), and Operational Readiness (0–100). The single largest gap is in margin visibility: 67% of firms assessed score below 50 on the margin dimension, meaning they cannot identify their most and least profitable projects with confidence Estimate. Utilization tracking is comparatively stronger, with a median score of 61/100 Estimate. Concentration risk is widely underestimated — 58% of assessed firms derive more than 30% of revenue from a single client Estimate. Operational readiness is the strongest predictor of overall performance: firms scoring above 70 on readiness average 22 points higher across all other dimensions Estimate.
The ProServ Health Assessment is a free diagnostic tool designed for project-based professional services firms with 15–100 employees. The assessment evaluates operational maturity across four dimensions, each scored from 0 to 100. The composite score is the weighted average of these four dimensions, calibrated against industry benchmarks for firms of similar size and service model.
The data synthesized in this analysis reflects patterns observed across assessment completions, supplemented by findings from the Margin Diagnostic and Firm Benchmarking tools. All data points derived from assessment scoring patterns are labeled with Estimate tags. These estimates represent directional findings intended to illustrate common patterns — they are not statistically validated research claims. As the assessment dataset grows, we will update this analysis with more precise figures and confidence intervals.
Median score. Measures whether the firm tracks billable hours, connects them to capacity, and reviews utilization weekly.
Median score. Measures whether the firm can identify project-level and client-level gross margin with fully-loaded labor costs.
Median score. Measures revenue distribution across clients and awareness of dependency on top accounts.
Median score. Measures systems maturity, reporting cadence, process documentation, and data integration.
The sample composition skews toward owner-operated firms running QuickBooks Online or Xero, billing on a project or retainer basis, and operating without a dedicated Controller or CFO. This is by design — the assessment targets exactly this profile. Firms with enterprise ERP systems or established PSA platforms typically score higher across all dimensions and are not the primary audience for these tools.
Each dimension score reflects both capability (does the firm have the systems and data to measure this?) and practice (does the firm actually review and act on this data regularly?). A firm that has timesheet software but never reviews utilization reports scores lower than a firm that tracks hours in a spreadsheet but reviews weekly. Systems without practice produce data that sits unused. Practice without systems produces gut instinct that cannot be validated.
The assessment data tells a consistent story: most professional services firms in the 15–100 employee range are partially instrumented. They track hours. They have a P&L. They know their biggest clients. But they have not connected these data sources into a system that produces actionable weekly intelligence. The result is operational decisions made on intuition where data should exist.
Four specific action items emerge from the findings:
Margin visibility is the biggest blind spot and has the highest ROI to fix. Connect your timesheet hours to fully-burdened cost rates. Even a rough calculation (base salary + 30% for benefits and taxes, divided by available hours) produces a cost-per-hour that can be multiplied by project hours to get project-level labor cost. Subtract from project revenue to get project gross margin. Do this for your top 10 clients this week. The Margin Diagnostic automates this with 13 weeks of data.
Start here: connect timesheets to cost ratesPull your last 12 months of revenue by client. Calculate each client's share of total revenue. If any single client is above 25%, you have concentration risk that should be tracked monthly and managed with an explicit diversification plan. If above 40%, this is a structural vulnerability that affects your firm's valuation, your ability to negotiate rates, and your resilience to a single client loss. See our client concentration deep-dive for the full framework.
Threshold: flag any client above 25% of revenueOperational readiness is the multiplier. The single highest-impact readiness improvement is a weekly 30-minute review of three numbers: team utilization rate, project margin by client, and pipeline coverage ratio. Monthly reviews are too slow — you discover a utilization drop four weeks after it happened. Weekly reviews create a feedback loop where problems are identified in days, not months. The ProServ Health Assessment identifies your specific readiness gaps.
Cadence: 30 minutes weekly, 3 key numbersBefore setting targets, know where you stand relative to peers. A 68% utilization rate is strong for a consulting firm with senior-heavy staffing and might be weak for a staffing-model IT services firm. Context matters. The Firm Benchmarking report compares your metrics against firms of similar size, vertical, and billing model. Targets without context are arbitrary. Targets calibrated against your peer set are actionable.
Know your peer set before setting targetsThe median score of 52/100 means the typical firm in our sample has significant room for improvement — but also has foundational elements in place. Most firms are not starting from zero. They are starting from disconnected data. The fastest path to operational visibility is not a new ERP system or a PSA migration. It is connecting the three data sources they already have (timesheets, payroll, billing) into a weekly reporting cadence that surfaces the metrics their P&L cannot show.
The ROI Calculator estimates the financial impact of closing the visibility gap for your specific firm size, utilization rate, and average billing rate. For a 30-person firm billing at $175/hour with 68% utilization, a 5-point utilization improvement represents approximately $273,000 in additional annual revenue Estimate — with no new clients and no new headcount.
Based on ProServ Health Assessment data, the median score for firms with 15–100 employees is 52 out of 100 Estimate. Firms scoring above 70 across all four dimensions — Utilization, Margin, Concentration Risk, and Operational Readiness — consistently outperform on revenue growth and profitability. A score below 40 indicates significant operational blind spots that are likely costing the firm 10–20% of potential margin. The goal is not to reach 100 — it is to identify and close the specific gaps that have the highest financial impact for your firm. Take the free assessment to see where you stand.
The assessment scores firms on four dimensions, each rated 0–100. Utilization measures whether the firm tracks billable hours, connects them to capacity, and reviews utilization rates regularly. Margin measures visibility into project-level and client-level gross margin using fully-loaded labor costs. Concentration Risk measures revenue distribution across clients and awareness of dependency on top accounts. Operational Readiness measures systems maturity, reporting cadence, and data integration. The composite score is a weighted average. Each dimension reflects both capability (do you have the systems?) and practice (do you actually use them?).
Margin visibility is the largest gap by a significant margin. 67% of assessed firms score below 50 on the Margin dimension Estimate. Most firms track total revenue and have a P&L, but cannot identify their most and least profitable projects at the engagement level. The root cause is a data connection problem: timesheet data (hours per project) is not connected to payroll data (fully-burdened cost per hour) and billing data (revenue per project). Closing this gap requires connecting three existing data sources, not purchasing new systems. The Margin Diagnostic performs this analysis using 13 weeks of your actual timesheet data.
Operational readiness is the strongest predictor of overall performance in the assessment data. Firms scoring above 70 on the Readiness dimension average 22 points higher across Utilization, Margin, and Concentration Risk Estimate. This correlation exists because readiness represents the infrastructure that makes other metrics visible and actionable: weekly reporting cadences, connected data sources, defined review processes. Improving readiness has a multiplicative effect — a firm that installs a weekly review rhythm will typically see improvements across all other dimensions within 8–12 weeks, not because the metrics changed but because the awareness and response time improved.
