How should owners compare their CAS practice with a national benchmark survey?

Which comparison is the CAS owner trying to make?

A national CAS benchmark can help an owner investigate operating performance, service scope, staffing, or pricing. It cannot answer those questions well until the local practice and benchmark use comparable definitions. Decide whether the goal is to evaluate productivity, client economics, growth, margin, or transaction readiness before selecting a figure.

Describe the practice’s actual services. Recurring bookkeeping, controller work, CFO advice, cleanup projects, tax preparation, payroll, and implementation can be bundled differently. A local practice calling its offering CAS may have a different mix from the survey population. The label alone cannot establish an appropriate comparison.

The market hub supplies broader context and the CAS definition explains terminology. The national-data pricing guide separates operating benchmarks from transaction evidence. This review focuses on whether a comparison is analytically useful before drawing an operating or sale conclusion.

What does the published benchmark actually describe?

The 2024 CPA.com and AICPA PCPS report describes self-reported survey responses. Its methodology identifies 206 self-selected respondents, with differing response counts across questions. It reports medians rather than means. Those population and measurement details belong alongside any selected figure.

The release’s observation period also matters. CPA.com’s December 2024 survey announcement identifies 2023 calendar-year data. A report published in 2024 is not a current 2026 operating census. Preserve both the publication date and underlying period.

The report distinguishes observed growth from projections. It gives a 17% median growth observation and a 99% projected median increase over three years. The latter is respondents’ forecast, not realized growth or a promise of results for the local practice. Do not merge those categories into one current market claim.

A survey can still provide valuable questions despite its limits. The owner should identify what is being compared, why the respondent population is relevant, and which local facts differ. The goal is to make those differences explicit rather than either dismiss the report or import all of its conclusions unchanged.

Which definitions can materially change the result?

The report classifies top performers by the upper quartile of net client fees per professional. Its metric uses annual reportable CAS revenue net of write-offs divided by full-time-equivalent staff, including outsourced and offshored staff. That category is a defined productivity ranking, not a universal ranking of every dimension of practice quality.

The reported CAS margin uses revenue less staff costs divided by revenue. Its comparison table notes that the 2024 definition no longer includes overhead allocation. Comparing that measure directly with a local fully loaded margin or an earlier differently defined figure can therefore be misleading.

Establish the local numerator and denominator independently. Identify included services, write-offs, periods, staff groups, owner effort, support costs, and overhead treatment. A metric with the same name can still have a different construction. Reconcile definitions before interpreting a percentage or declaring a productivity gap.

Keep client units consistent as well. An entity, related group, monthly package, or separate service engagement may be counted differently. Describe how the practice treats related clients and bundled services. A change in client counting can move revenue per client without changing the economics of the underlying work.

How can a benchmark eligibility card organize the comparison?

Prepare a benchmark eligibility card: a record showing the metric, survey definition and population, local construction, material differences, and the question the comparison can reasonably inform. Create a card for each metric rather than approve the entire survey as one comparable.

A card can conclude that a comparison is useful only for a narrow question. For example, a productivity difference may warrant investigating staffing allocation while leaving pricing or sale value unresolved. State that use and avoid treating an operating metric as evidence for a decision it cannot support.

Record the evidence gap if definitions cannot be reconciled. Do not assign missing staff time, overhead, or service revenue arbitrarily and describe the adjusted result as verified. The card should tell the owner which records to obtain and what conclusion must remain conditional.

How can illustrative arithmetic expose a staffing mismatch?

Assume an illustrative CAS practice has $480,000 of net client fees and four full-time-equivalent staff. Dividing produces $120,000 per FTE. If another full-time-equivalent of outsourced work is omitted, the same revenue is actually supported by five FTE, producing $96,000 per FTE under that assumed scope.

Those invented example numbers demonstrate denominator sensitivity; they are not a published benchmark or observed practice. The owner must determine the actual staffing allocations and which groups the relevant metric includes. A higher apparent productivity result can reflect omitted work rather than improved delivery.

Owner effort deserves the same attention. An owner can supply production, review, client leadership, and management across several service lines. Establish the actual work and the proposed replacement arrangement for transaction analysis. Do not assume a productivity comparison resolves the cost or feasibility of replacing the owner’s duties.

Growth-stage hiring can also change the interpretation. A practice building capacity before new clients arrive may show a different current revenue-per-FTE result from a mature practice using established capacity. Examine that operating fact instead of automatically treating the lower figure as poor performance or the higher one as sustainable.

How should the owner translate a comparison into action?

Identify the cause to investigate before choosing a remedy. A difference can arise from service scope, client mix, price, write-offs, staffing allocation, training, review, or unfinished cleanup work. Ask the team to document the relevant workflow and economics rather than assume every gap calls for immediate price increases.

Select one operating question that can be tested with existing records. Compare similar engagement groups over a defined period, preserve scope, and examine preparation, review, exceptions, and client response. An improvement should be evaluated against the service promise and actual collections, not only a headline productivity ratio.

The client-brand response guide offers a related discipline: record actual client behavior when service or pricing changes. A national respondent projection cannot establish local acceptance. Separate the owner’s proposed action, expected result, and evidence observed after implementation.

The FTC’s covered-firm information-security resource addresses safeguards for covered organizations. When testing a new workflow or outsourced arrangement, assign permitted access, secure systems, provider responsibilities, and custody. A productivity objective should be implemented through an approved operating process.

How should benchmark evidence appear in a transaction file?

Keep the survey citation and eligibility cards in the research section, separate from the practice’s verified records and forecast assumptions. Identify the observation period, definitions, relevant respondent category, local construction, and supported use. Preserve material mismatches so a reviewer can assess the comparison independently.

Reconcile the seller’s current engagements, collections, staff effort, owner work, and remaining obligations before discussing value. Potential efficiency, repricing, or new services belong in a conditional operating case with assigned execution tasks. They should not be described as existing earnings merely because survey respondents reported favorable results.

The Midwest market overview puts the survey into broader context. The useful transaction conclusion is often a question to investigate or a practical operating improvement, not a market multiple. A disciplined CAS comparison preserves definitions and helps the owner decide what evidence is needed next.
