Why buyers price it so hard
A buyer assumes your largest customer leaves the month after close, because for them it might: the relationship is with you, the renewal conversation was yours, and the goodwill is not in the codebase. So they either drop the headline number or hold part of it back until the account renews under their name.
Where the threshold sits
| Largest customer | How a buyer reads it | Adjustment |
|---|---|---|
| Under 20% of revenue | A strength. Say the number early. | None |
| 20–30% | Noted, priced lightly, raised in diligence. | −7% |
| 30–40% | A named red flag in every advisor's checklist. | −14% |
| Above 40% | Structure changes: expect an earn-out. | −22% |
A ValuePulse model rule, not a published figure. Advisors name concentration above 30% as a red flag, but no source we could verify puts a number on the discount at this size — so we publish ours here for you to argue with.
The fix, in order of what actually works
- 01Grow the rest of the book. Slower, and the only fix that raises the price rather than defending it.
- 02Get a signed multi-year renewal with a notice period. A contracted account is discounted far less than a month-to-month one, and this is achievable in weeks.
- 03Move the relationship off yourself: shared inbox, documented account history, a second name they know. Buyers check whether the customer knows anyone but you.
- 04Where it is genuinely true, split a large customer into separate contracts by entity or business unit. Never dress up one account as several — diligence finds it and the deal does not survive it.
Timing matters more than effort here. Any of these done before you open a conversation shows up in the price. The same fix offered mid-diligence reads as a concession, and the buyer has already repriced.
