A large customer can provide useful recurring work while also making the business dependent on one relationship. A revenue percentage alone does not tell you which action to take. Review what would change if that customer reduced activity, what costs or capacity would remain committed, and how long a replacement opportunity might take. Use the exercise to choose a concrete operating response, not to declare every large account a problem.
Measure Dependence In More Than One Way
Start with a defined period and consistent records. Calculate the customer’s share of recognized revenue, then look separately at cash received, scheduled work and capacity assigned. These measures answer different questions. A large payment arriving this month may relate to work already completed, while a smaller current invoice may support a much larger forward commitment.
Illustrative calculation: one customer represents $50,000 of $120,000 in monthly revenue, or about 41.7 percent. That describes the revenue mix; it does not establish profit, available cash or a universal danger threshold. Keep accounting treatment consistent with the business’s records and involve the responsible finance adviser where classification is uncertain.
Describe A Specific Change Scenario
Choose a plausible change to examine, such as a reduction in monthly work, a delayed project start or the end of a defined engagement. Do not combine every possible setback into one dramatic forecast. Record the assumed timing and the contracts or operating facts that need qualified review before the scenario can inform a real decision.
List the work, staffing commitments and supplier obligations affected by that change. Separate resources that could move to other customers from costs that would continue. A revenue loss and a contribution loss are different quantities. Avoid subtracting a headline revenue figure from a cash balance and treating the result as a complete forecast.
Compare The Response Time With The Exposure
Estimate the steps required to replace the affected work: identify a suitable prospect, reach a decision, agree scope, start delivery and receive payment. Use the business’s observed process where available and show uncertainty when the evidence is thin. A strong pipeline count is not proof that another customer can start or pay at the required time.
For example, a scenario may free forty delivery hours while the current team has only fifteen hours of suitable replacement work ready to schedule. The immediate unassigned difference is twenty-five hours. That does not automatically justify a discount or a staffing change. It identifies a specific gap for the owner to examine alongside costs and timing.
Choose A Response That Fits The Constraint
If the issue is dependence on a single relationship, broaden appropriate contacts within that customer’s organization and make the delivered value visible. If the issue is a thin replacement pipeline, test a defined acquisition effort. If the problem is a commitment made too far ahead of demand, review how future work is scheduled and authorized.
Avoid rejecting valuable work solely to improve the concentration percentage. Adding low-quality revenue can make the ratio look healthier while increasing delivery strain. Compare proposed actions by the exposure they reduce, the resources they require and the evidence that would justify continuing. Account growth and diversification can both be reasonable, depending on the actual constraint.
Set A Review Trigger And An Owner
Create a short decision note containing the customer, observation period, scenario, unresolved assumptions, chosen action and next review date. Add triggers tied to events the team can observe, such as a changed project schedule or a renewal decision. A percentage alert without an owner tends to become a recurring discussion rather than a response.
At the review, compare actual developments with the assumptions. Retain changes to the scenario so the team can see whether risk reduced or the estimate simply moved. Keep commercially sensitive customer details in the approved internal record. The public marketing plan needs the resulting priorities, not a client-by-client exposure table.
Common Questions
What Customer Concentration Percentage Is Safe?
This framework does not set a universal safe percentage. Evaluate the relationship, contribution, commitments, replacement time and the business’s own tolerance for disruption. Use qualified financial or contractual advice for decisions that depend on those specifics.
Should The Largest Customer Be Given Less Attention?
Concentration analysis can reveal reasons to strengthen delivery and communication as well as reasons to diversify. Choose actions that address a defined exposure; neglecting a valuable relationship merely to change a ratio can create the problem the review was intended to prevent.
