Professional services
Applying specialist judgment to a client problem.
Professional firms sell expertise through projects, retainers, or continuing services. Work depends on scarce skills, client trust, and the ability to turn an uncertain brief into a defined deliverable. Time is an input, but the customer may pay for an outcome or a fixed scope.
What to look for
Look at utilization alongside realization, project margin, and client concentration. More billable hours can conceal underpricing or rework. Methods, reusable knowledge, staffing leverage, and quality review explain how a firm can grow beyond the capacity of its founders.
