We are planning an external sale in thirty-six months, but our top client accounts for thirty-five percent of our total revenue. How do we systematically mitigate this customer concentration risk on our exit runway without risking the relationship?

Customer concentration is one of the most severe valuation killers in a business sale. If a single client represents over thirty percent of your revenue, institutional buyers will view your company as highly risky and will heavily discount your multiple or demand a large earn-out. You must systematically dilute this concentration over your exit runway.

First, use your leadership team's quarterly planning session to adjust your Rocks. Set a specific quarterly Rock for your sales leader to diversify your client base. This does not mean neglecting your largest client. Instead, it means aggressively expanding your other accounts and signing new business to naturally shrink the percentage that your top client occupies on your EOS® Scorecard.

Second, formalize the contract terms with your major client. Buyers want predictability. Work to secure a multi-year, master service agreement with clear transferability clauses that will remain valid after a change of control.

Third, transition the day-to-day relationship of this key account away from yourself as the owner. Introduce other members of your leadership team to the client's decision-makers. Ensure your operations seat and key account managers are the primary contacts. When a buyer conducts customer due diligence, they must see that the relationship belongs to the business entity and its systems, not to you personally. By decoupling yourself and securing long-term contract commitments, you transform a major operational risk into a stable, transferable asset.
