Accounting firm capacity, fees and profitability

Start from usable hours

Contracted hours are not all available for client work. Leave, internal administration and a buffer reduce delivery capacity. Review can become the bottleneck even when preparers have spare time, so do not merge both roles into one comfortable total. Use an annual calendar to identify recurring peaks, then examine the week that is actually constrained.

Choose a metric that answers the question

Utilization describes a share of time; realization compares a defined value with another defined value. Neither alone tells you whether a client is profitable. For that, compare the fee with the delivery costs you decided to include. State the denominator and period whenever sharing a percentage, and investigate repeated overruns instead of treating every exception as a staff-performance problem.

Price a named scope

A fixed fee needs assumptions about transaction volume, employee counts, reporting and client responsiveness. Separate the work included in the agreement from additional work. Estimate direct delivery costs and allocated overhead before choosing a target margin. Margin is a share of revenue; markup is a share of cost. Mixing them gives a misleading price.

Make a fee change reviewable

When costs or scope change, explain the observed difference, the revised scope and the effective date. Preserve the agreement rather than silently changing a recurring amount. The reading path below moves from annual planning through capacity and client economics to scope and fee communication. Numerical examples are working assumptions, not market benchmarks or a promise of results.
