Receivables Strategy

The Hidden Risk in Customer Concentration

Your top customer represents 35% of your sales. That's success, right? Until that customer files bankruptcy and you lose a third of your annual revenue overnight. This is the concentration trap—and it's more common than you might think.

What Concentration Risk Looks Like

Concentration risk occurs when a significant portion of your business is dependent on a small number of customers. This can manifest in several ways:

  • Single customer concentration: One customer represents 20%+ of revenue
  • Industry concentration: Most customers operate in the same sector
  • Geographic concentration: Customers are clustered in one region
  • Product concentration: One product line drives most sales

The Math That Breaks Businesses

Let's say you have $5M in annual revenue with 15% net profit margin ($750K). Your top customer is 40% of sales ($2M), with $300K in outstanding receivables.

That customer files bankruptcy. You recover 15 cents on the dollar.

Result: $255K loss = 34% of your annual profit wiped out.

Why We Underestimate Concentration Risk

Big customers feel safe. They're reliable, they've been around for years, and they're creditworthy—until they're not. The problem is that past performance doesn't guarantee future results, especially in challenging economic conditions.

There's also a psychological component: we don't want to rock the boat with our biggest accounts. So we extend terms, increase credit limits, and increase exposure without proper analysis.

How to Manage Concentration Risk

Know Your Numbers

Track not just sales concentration, but receivables concentration separately. These often differ significantly.

Diversify Strategically

Actively pursue new customers in different industries or regions to reduce dependence.

Insure Concentrated Accounts

Credit insurance is especially valuable for concentrated exposures—transfer the risk you're least able to absorb.

Monitor Constantly

Set up alerts for changes in your top customers' credit profiles or financial health.

When to Act

If any single customer represents more than 15-20% of your receivables, that's a signal to review your risk management strategy. The goal isn't to eliminate large customers—it's to make sure their failure doesn't threaten your business.
