Client concentration measures how much the firm depends on a small number of clients. Pick a consistent measure and period, such as collected revenue during the last fiscal year or authorized backlog at a given date. Report both if each helps answer a different question. Do not mix revenue, proposals, and backlog into one figure.
Look through related entities to the parent organization, funding source, and decision makers. Several agencies or subsidiaries may depend on the same budget or procurement process. For each major client, review contract length, funding status, payment history, termination rights, upcoming procurement decisions, relationship depth, and whether the work relies on one contact or one owner. Ask project managers what would happen to staffing and cash if a major task order stopped.
Concentration can make revenue and hiring more exposed to a single cancellation, budget shift, procurement delay, or relationship change. It is not automatically a sign of poor management. A specialist firm may intentionally serve a narrow market and develop deep expertise. The owner still needs a plan for a disruption, including cash reserves, staff reassignment options, and a way to maintain client relationships if a key employee leaves.
Use the analysis to make measured choices. Identify adjacent clients or services that fit existing capabilities, then assess whether the firm has qualified staff, licenses, insurance, and time to deliver them. Avoid pursuing work that the firm cannot competently perform simply to add names to the client list. Set relationship coverage so more than one leader understands each major client’s needs and contract history.
Review concentration at least when budgets, contracts, or ownership plans change. Ask your CPA how to calculate the chosen measure consistently, and ask your attorney to review contract terms that affect continuity or termination.
Begin by organizing financial statements, project records, client agreements, staff information, and a clear explanation of owner duties. A valuation professional can assess earnings, cash flow, backlog quality, client relationships, staff retention, risk, and market conditions using an appropriate method. For example, a firm that depends on one owner for most client relationships may need a transition plan as part of the value discussion. Ask what assumptions drive the conclusion and how a buyer could verify them. Keep the estimate distinct from a negotiated sale price.
