Agency Billable Utilization: Compare Targets and Fix the Causes

Use a consistent calculation, investigate the work behind the percentage and choose a role-appropriate improvement plan. Includes links to the free calculator and calculation guide.

A utilization target is useful only when you know what it counts. A low percentage might reflect missing time, limited client demand, sales responsibilities or a capacity denominator that includes leave. A high percentage can coexist with an overrun or an underpriced fixed-fee project.

Start with the billable utilization calculator. For definitions and a worked illustration, follow how to calculate billable utilization. This playbook focuses on interpreting the result and choosing an action, rather than providing another calculator.

Compare benchmarks on the same basis

Before comparing your percentage with an industry survey or another agency, check:

  • Definition: eligible billable work, hours invoiced, or billable share of recorded work?
  • Capacity: contracted hours, or hours after leave and holiday exclusions?
  • People: delivery specialists, project managers, partners, or the whole business?
  • Period: a busy week, a quarter or a full year?
  • Evidence: who was surveyed, when, and how was the result collected?

If those details are unavailable, use the number as a discussion prompt rather than a performance standard. Start with your own consistently measured baseline when setting a target.

Set your internal targets around each role's responsibilities. Delivery, sales, mentoring, account management and administration all require time. Raising every person's utilization target to the same level can simply hide necessary work.

Find where the time went

Review recorded work alongside the expected schedule. Keep client delivery, internal work, leave and unexplained gaps distinguishable. A gap between recorded hours and capacity needs investigation; it is not automatically unused capacity or lost revenue.

Short client conversations, revisions and review tasks are easy to miss. Recording them makes effort visible, but whether they qualify as billable still depends on the agreement and your policy. Do not reclassify work just to improve a metric.

Also examine the denominator. A utilization increase caused solely by excluding more hours from capacity is different from an increase in eligible client delivery. Note definition changes when comparing periods.

How to improve utilization: the playbook

1. Make time recording practical

Use the timer or manual entry process that fits the work, with consistent project and task associations. Review entries regularly while the details are still fresh. Explain why internal work matters to the review, so people do not feel pressure to record only client tasks.

Measure data completeness before interpreting utilization. Missing billable work can understate utilization against fixed capacity; missing internal work can inflate billable share of recorded time.

2. Review meetings by purpose

List recurring meetings, their participants and the decisions they support. Shorten, combine or remove sessions where the purpose can be met more efficiently. Keep necessary coordination and training visible.

A weekly status report can organize progress, blockers and decisions before a discussion. Any time saved becomes available capacity; it becomes billable work only if suitable, agreed client work is available.

3. Reduce repeated administration

Identify repeated entry, unclear handoffs and missing information. Use a consistent onboarding checklist and a documented sales-to-delivery workflow.

In Corcava, estimate-to-project and estimate-to-invoice conversion are explicit actions. Do not build an improvement plan around assumed automatic client onboarding, scheduled status reports or conversion of every recorded hour into an invoice.

4. Improve scoping with actual effort

Compare completed work with the original estimate and explain the differences. Was the work underestimated, repeated, blocked or expanded? Those causes require different changes to the next proposal.

Use a change request to record proposed scope, cost and timing before treating extra work as approved. Review the project-profitability example alongside utilization: more recorded client work can increase delivery cost without increasing a fixed fee.

5. Match assignments to skills and capacity

Review who can perform the work, who needs support and who has capacity in the relevant period. Include the coordination and review effort in the plan. Moving a task to someone with a different rate does not guarantee a lower total cost or additional sales for the person whose time is freed.

6. Review recurring commitments

Recurring engagements can help planning when their scope, expected effort and timing are clear. They can also absorb more time than their fee supports. Use the retainer profitability calculator to test assumptions, then compare them with recorded delivery effort.

7. Resolve classification questions

Client research, documentation, training and support may belong to an agreed scope. Proposals and internal development may instead be business-development costs. Check the agreement and record the decision consistently. An internal change in classification does not itself authorize a client charge.

A 90-day review plan

This is a suggested cadence, not a promised outcome:

Period Review focus Output
Days 1–30 Define the metric and collect a consistent baseline Written numerator/denominator policy and list of data gaps
Days 31–60 Investigate causes and try a small process change Named action, owner and a way to assess its effect
Days 61–90 Compare like-for-like periods Decision to keep, adjust or stop the change

Use the same people, periods and capacity rules where possible. Record material differences such as leave, a new engagement or a role change. Review workload and delivery quality alongside the percentage.

Read the product reports within their limits

Corcava's Reports provide recorded hours and rate-based values, with grouping that helps trace work by person, project, client or task. The report's Billed amount is hours valued at a bill rate; it is not utilization, an invoice total or cash received.

Prepare utilization using the reviewed hours and a separate capacity source. Prepare project contribution using a stated revenue or modeled-value basis, cost basis and expenses. This method does not rely on a native utilization dashboard, automated client P&L or an automatic margin percentage.

Keep the next action specific

Choose an action you can evaluate: fix missing project assignments, clarify how a category is treated, shorten a repeated handoff or review an estimate that consistently misses work. Avoid using one person's percentage as a judgment without understanding their responsibilities and data.

Use the calculation guide to keep the math consistent, and the client-profitability method to assess the wider relationship. Improving the percentage is useful when it supports sustainable delivery and sound economics.
