Our largest client represents roughly thirty percent of our total gross margin, which brokers tell us will trigger an earnout or a heavy valuation haircut. How do we systematically dilute client concentration over a three-year runway without intentionally shrinking that account?

Question

Tyler Smith · Accepted Answer

When a single client generates twenty-five to thirty percent of your revenue, institutional buyers see catastrophic risk. Even if that client has been loyal for a decade, buyers assume the relationship could vanish after ownership changes. They will discount your multiple, demand aggressive earnouts, or require substantial seller notes.

Firing a profitable account to improve your concentration percentages makes no sense. Instead, de-risk the relationship methodically over a three-year runway through deliberate dilution and institutionalization:

- Dilute through focused new business acquisition: Use your Target Market definitions in your V/TO® to focus your sales engine entirely on acquiring right-fit customers. If you grow non-concentrated revenue by twenty percent annually while holding the legacy account stable, that thirty percent concentration naturally shrinks below twenty percent within three years.
- Institutionalize the account relationship: If you personally manage the concentrated customer, you compound buyer panic. Transfer account leadership to a capable team member on your Accountability Chart. Introduce client leadership to your operations, project delivery, and finance leaders so the account is anchored across multiple touchpoints.
- Secure long-term multi-year commitments: Convert the customer from purchase-order or month-to-month arrangements to a formal, multi-year master services agreement. Ensure the contract includes clear renewal terms and assignability clauses that survive an ownership transition without triggering termination rights.
- Measure gross margin contribution: Ensure that the concentrated client is genuinely profitable on a fully burdened basis. Often, legacy accounts demand high customization and administrative overhead that secretly erodes margin. If you must carry concentration risk, make sure your Scorecard proves the account generates premium margins that fund your ongoing diversification efforts.

When buyers see long-term contracts, multi-level relationship coverage, and shrinking percentage concentration, their panic subsides, protecting your valuation at the closing table.
