Our largest client represents over thirty percent of our annual revenue, and advisors say this will trigger massive buyer discounts or an earnout. How do we systematically derisk this on our exit runway?

Question

Tyler Smith · Accepted Answer

Customer concentration is one of the fastest ways to kill a cash deal. If any single customer accounts for more than fifteen to twenty percent of your top-line revenue, institutional buyers will assume that client relationship is tied to you personally or that losing them will bankrupt the company.

To protect themselves, buyers will demand heavy earnouts, seller notes, or severe valuation haircuts. You can solve this on your multi-year exit runway by attacking the problem through operational discipline:

- Deepen organizational ties to the major account. Ensure that your Integrator and operational account managers own the daily relationship, not you. Introduce structured multi-year enterprise contracts with clear renewal terms and non-cancelable clauses. If the client cannot leave easily, buyer risk declines.
- Use your V/TO to re-align sales capacity toward high-margin target market prospects. Set clear quarterly Rocks for your sales seat dedicated to client acquisition outside of that single major account.
- Do not attempt to fix concentration by firing or neglecting the large account. Instead, aggressively grow the rest of the business around it so that their percentage of total revenue naturally dilutes over twenty-four to thirty-six months.

When a buyer sees that a legacy top account is governed by institutional systems and managed by a dedicated team, your concentration becomes an asset of proven client retention rather than a fatal liability.
