How to use this scorecard
Run this once a month, or whenever your calendar feels full but fragile. You are looking for concentration, not just busyness: who owns your revenue, your meetings, your mental load, and your leverage.
If the same client dominates three of those at once, treat it as a strategic warning even if the month looks healthy on paper. Concentration can feel safe right until the client changes priorities, slows payment, demands extra work, or ends the relationship.
What concentration really means
Revenue concentration is the obvious metric, but capacity concentration is often the earlier warning. A client may represent 35% of revenue and 70% of meetings. Or they may represent 40% of revenue and 90% of mental switching. That client owns more of the business than the invoice total suggests.
- Revenue concentration: how much current income depends on one account.
- Calendar concentration: how much meeting time one account consumes.
- Mental load concentration: how often one account interrupts other work.
- Proof concentration: whether the work creates reusable proof or traps you in invisible maintenance.
How to act on your review
This is a manual review, not a calculated risk score. The checklist percentage shows completion only. Record the measurements in your own notes and judge them alongside payment terms, workload, and replacement opportunities. There is no universal percentage that makes a client safe.
Use the same period for each comparison. Divide that client's revenue by total revenue, then multiply by 100. For meetings, compare meeting hours with total client meeting hours. Record mental load as an estimate and note what caused interruptions; avoid treating it as precise accounting.
If risk is moderate
- Keep one active prospecting lane.
- Protect weekly sales/admin blocks.
- Document proof from current work.
- Avoid adding more custom obligations.
If risk is high
- Price the risk in renewal terms.
- Shorten payment cycles or require deposits.
- Reduce meeting load and async churn.
- Create a replacement pipeline before renewal pressure.

FAQ
What if I cannot diversify yet?
Then price the concentration risk, protect terms harder, and keep some lightweight pipeline motion alive. Diversification does not need to be dramatic. It can start with three warm follow-ups and one replacement offer.
Is one big client always bad?
No. One big client can be excellent if terms, payment, scope, and proof value are strong. The problem is unpriced dependency, not success.
