When Many Customers Suddenly Become One
How customer acquisitions can transform diversification into concentration
A Customer Base That Looked Diversified
I encountered a service business with relationships among numerous independently operated customers. For confidentiality, the industry and identifying circumstances have been generalized.
The company had a good reputation and ongoing relationships with many customers. No single operating location seemed to represent an unusually large share of revenue.
But a larger organization had already acquired a number of those customers. Their individual locations remained, while management and administrative functions were beginning to be centralized. I could see this becoming a serious issue.
The First Risk: Many Customers Become One
Before consolidation, losing one independently owned customer might have been manageable. After acquisition, a corporate-level decision could affect many locations at once.
The service company hadn't lost customers or changed its own sales strategy. But the ultimate control of purchasing decisions was increasingly concentrated.
A business can become heavily dependent on one customer without making a single additional sale to that customer.
The Second Risk: A Small Expense Becomes a Large One
The service expense had been relatively insignificant to each individual business. Owners or managers were satisfied and saw little reason to solicit bids.
Across the consolidated group, that same expense became a meaningful combined purchasing category. Centralized management might seek alternative quotes, negotiate volume discounts, standardize vendors, or bring work in-house.
Consolidation increased both the consequences of losing the business and the likelihood that the relationship would be reevaluated. Those two risks reinforce one another.
Why Buyers Should Care
Twenty accounts on a sales report might represent twenty independent purchasing decisions—or twenty locations controlled by one corporation. They are not equivalent.
A buyer needs to know who ultimately controls customers, whether purchasing is being centralized, and whether risks have emerged that are not yet visible in historical revenue.
A Related Risk: Industry Concentration
Even without common ownership, customers operating in the same industry can be affected together by economic, regulatory, or technological changes. A product or service can become obsolete across an entire customer segment.
Customer diversification therefore requires looking beyond account names to ownership, decision-making authority, and shared industry exposures.
The Lesson
Owners should watch for customer acquisitions, purchasing centralization, new bidding requirements, and the share of revenue ultimately controlled by a single group.
Customer concentration isn't determined solely by how many names appear on your customer list. It's also determined by who controls the decisions behind those names.
