While our largest account accounts for only eighteen percent of total top-line revenue, they generate thirty-four percent of our company gross margin. How will an institutional buyer evaluate this gross profit concentration, and how do we defend our multiple?

Question

Tyler Smith · Accepted Answer

Sophisticated buyers do not stop at revenue concentration; they evaluate gross margin and EBITDA concentration. An account that represents eighteen percent of revenue but thirty-four percent of gross profit presents an outsized vulnerability. In financial diligence, the buyer will conclude that losing this single client would erase more than half of your enterprise free cash flow, prompting them to haircut your EBITDA multiple or demand aggressive earnouts.

To defend your multiple, you must present a multi-layered defense anchored in operational stickiness and pricing sustainability. Show that this account's high margins are not an anomaly of unrepeated price gouging, but the result of delivering specialized, proprietary value with high switching costs. Present contract documentation demonstrating multi-year commitments, automated renewal language, and intellectual property integration.

Operationally, show multi-threaded engagement on your Accountability Chart. Prove to the buyer that client communication, account management, and strategic roadmapping are run by dedicated leaders through structured quarterly reviews, completely independent of the business owners.

Complement this by highlighting customer acquisition momentum on your EOS Scorecard. Show that your new business pipeline has healthy gross margins across recent wins, proving that the account in question is a template for your target market rather than a historical accident. If the buyer still pushes for a discount, convert the disputed margin into a short-term seller note rather than taking an outright enterprise value cut.
