Customer concentration: Customer concentration is the share of a business total revenue that comes from its largest single customer or handful of customers, and it is one of the biggest risk factors a buyer weighs when pricing an acquisition.
How much is too much
Buyers generally start flagging concentration risk when one customer exceeds about 15 to 20 percent of revenue, and get seriously concerned above 30 percent. The reason is simple: if losing a single account would gut the business, the buyer is exposed to a risk they cannot control, so they lower the multiple or add contingencies to the deal. The more concentrated the revenue, the more the price is discounted.
How to reduce the discount
The durable fix is diversification: grow the smaller accounts and add new ones so no single customer dominates. Where concentration cannot be reduced before a sale, long-term contracts, deep multi-person relationships, and a documented history of retention all reduce how much a buyer discounts for it. An operator-buyer who understands the industry can sometimes underwrite concentration a passive financial buyer will not touch.
Frequently asked questions
How much customer concentration is too much when selling a business?
Buyers typically begin flagging risk when a single customer exceeds about 15 to 20 percent of revenue, and treat above 30 percent as a serious concern. Higher concentration means a lower multiple, because losing one account could threaten the whole business.
Does customer concentration lower my business value?
Yes. Concentration is a risk a buyer cannot fully control, so they price it in by lowering the multiple or adding deal contingencies. Reducing concentration, or locking in long-term contracts, is one of the higher-return things you can do before a sale.
How do I reduce customer concentration before selling?
Grow your smaller accounts and add new customers so no single client dominates revenue, and where you cannot diversify quickly, secure long-term contracts and broaden the relationships beyond one contact. Both reduce how much a buyer discounts for the risk.
