Client concentration is the most common structural vulnerability in independent consulting firms. It happens gradually. You land a large client, the work expands, and before you notice, one relationship accounts for the majority of your income. It feels like success until that client pauses, restructures, or changes direction. Then it feels like an existential crisis.
The Clients module inside Studio:Blueprint Operate measures concentration risk as a continuous score, not a binary flag. A firm with three clients at 40/35/25 has a different risk profile than a firm with six clients at 30/20/15/15/10/10. Both have concentration, but the shape of the risk is different. The engine captures this nuance.
The Clients module maps each client on two axes: economic value and delivery effort. This produces four quadrants. High value, low effort clients are your ideal relationships. High value, high effort clients are economically important but operationally demanding. Low value, high effort clients are the ones eroding your margin and attention. Low value, low effort clients are manageable but not moving the business forward.
This mapping reveals portfolio imbalances that revenue figures alone cannot show. A firm generating £200k from three clients might look healthy until you see that two of those clients sit in the high-effort quadrant and are consuming 70% of capacity. The revenue is real but the delivery economics are unsustainable.
The engine calculates each client's revenue share as a percentage of total revenue. When any single client exceeds 40%, a warning fires. Above 55% triggers a critical alert. These are not arbitrary thresholds. They reflect the point at which losing a single relationship creates a cash flow crisis that cannot be absorbed by remaining revenue.
The alert includes a specific recommendation: the revenue amount that needs to be diversified to bring concentration below the warning threshold. This is not generic advice. It is a specific target that connects to your pipeline module. If you need £30k of diversified revenue, the pipeline module shows whether your current opportunities can deliver it.
Client concentration is one of five axes in the Consultancy Health Index. It carries significant structural weight because concentration risk is existential, not incremental. A firm with weak pricing can adjust over time. A firm that loses its dominant client faces immediate revenue collapse. The CHI reflects this by weighting concentration heavily in the composite score.
Tracking concentration over time through the Cockpit's weekly snapshots shows whether your diversification efforts are working. The goal is not zero concentration. It is a portfolio shape where no single client loss creates a structural crisis.

The difference between knowing the concept and holding the number is the gap where margin erodes, pipeline stalls, or risk accumulates undetected. A structured diagnostic gives you the number, calculated from your firm’s actual inputs, not industry benchmarks or estimates.
