Most manufacturers would love to land a customer that represents 40%, 50%, or even 60% of their revenue. At first glance, it feels like success. The machines stay busy, production becomes more predictable, and revenue looks strong. It can take years to build that kind of relationship, and it’s something to be proud of.
But over the years, working with more than 25 manufacturers, I’ve learned that what looks like a strength on paper can quietly become one of the biggest strategic risks a company faces.
Customer concentration isn’t just a sales issue. It’s a business risk issue.
One of the first things I look at when I begin working with a manufacturer is where their revenue comes from. If a significant percentage is tied to one account, I don’t immediately see a problem. I see a conversation that needs to happen.
What would happen if that customer was acquired? What if they consolidated suppliers? What if a new procurement leader came in with a mandate to rebid every contract? What if they shifted production to another facility or experienced a downturn in their own business?
None of those decisions have anything to do with your performance. You may continue delivering exceptional quality, meeting every deadline, and providing outstanding service. Yet your business could still take a significant hit because of decisions being made in someone else’s boardroom.
I’ve seen it happen. That’s why I believe customer diversification isn’t just a sales strategy; it’s a growth strategy and a risk management strategy rolled into one.
This doesn’t mean treating your largest customers any differently. In fact, your best customers deserve exceptional service and attention. The goal isn’t to replace them. The goal is to make sure your company’s future isn’t dependent on a single relationship, no matter how strong it is today.
Ironically, many manufacturers wait until they lose a major customer before investing in business development. By then, they’re trying to replace revenue under pressure. That’s one of the hardest times to make strategic decisions because everything becomes reactive.
The better approach is to build your pipeline while business is strong. Continue deepening relationships with existing customers by looking for opportunities to expand your share of wallet, but at the same time, invest in reaching new markets, new industries, and new customers. Diversification isn’t about abandoning what’s working. It’s about ensuring that one customer doesn’t have the power to determine the future of your business.
The manufacturers that tend to weather economic uncertainty the best aren’t always the biggest or the fastest growing. They’re the ones that have built a balanced customer portfolio. When one market slows, another picks up. When one customer reduces spending, others continue to grow. They have options.
To me, that’s what sustainable growth looks like. It’s not simply about increasing revenue. It’s about building a business that’s resilient enough to withstand the changes none of us can predict.
So here’s my question for you. If your largest customer called tomorrow and told you they were cutting their business in half, what would your growth strategy be?
