One of our largest accounts accounts for thirty-five percent of our annual gross margin. How do we protect our business valuation on our exit runway without firing our best client?

Question

A thirty-five percent customer concentration is an immediate red flag in M&A due diligence. Strategic and financial buyers know that losing that single account could wipe out your entire EBITDA and leave the company unable to service its debt. The standard buyer reaction is to slash your multiple, demand an extensive contingent earnout, or walk away completely.

You do not fix customer concentration by firing the client or throttling their business. You fix it by aggressively building around them. Use your V/TO® to set specific revenue targets that dilute that client's percentage of total revenue down below fifteen percent over your exit runway. If your total gross margin grows from five million to twelve million dollars, that account naturally drops from thirty-five percent down to fourteen percent of your mix.

At the same time, institutionalize and fortify that client relationship to make it completely transferable. Multi-thread your operational connections across the account. If your CEO or founder is the primary contact, systematically hand off account stewardship to an account director and an operations manager. Secure a multi-year master services agreement with clear renewal terms, price escalations, and termination penalties.

When you enter the market, present this client not as a hidden hazard, but as a long-tenured, contractually secured proof of your firm's enterprise capability. If the buyer sees a multi-year contract, multi-layered points of contact, and an expanding book of other clients, your concentration risk becomes an operational asset.
