Why it matters for professional service firms

You cannot manage what you do not measure. Cost accounting provides visibility into what services actually cost to deliver. Professional service firms need cost accounting to price appropriately, analyze profitability accurately, and identify efficiency opportunities.

Real-world example

Chris priced engagements based on market rates without understanding costs. Cost accounting implementation: tracked direct labor by engagement, allocated indirect costs using an activity-based approach, and calculated fully loaded cost per service type. Discovery: Two service offerings were priced below fully loaded cost, subsidized by profitable services. Pricing adjustments: raised prices on underpriced services (one client declined, others accepted), and improved overall margin from 18% to 24%. Cost visibility enabled informed pricing.
