Customer concentration risk can have a significant impact on businesses, particularly those with a limited customer base. According to a study, 75% of companies with a highly concentrated customer base are more likely to experience financial difficulties.
Having a small number of large customers can create a dependence on them, making it difficult for the business to survive if any of these customers leave. This is evident in the case of a company that lost 30% of its revenue when a major client switched to a competitor.
Businesses with a high concentration of customers may also struggle to diversify their revenue streams, making them more vulnerable to economic downturns. For instance, a company that relies heavily on a few key customers may find it challenging to adapt to changes in the market or economy.
To mitigate this risk, businesses can take steps to diversify their customer base, such as targeting new markets or expanding their product offerings.

What is Customer Concentration Risk?

Customer concentration risk is a serious issue that can cause businesses to struggle or even fail. It's the risk a company faces when a large part of its revenue comes from a single or small group of customers. If you lose a key customer, you could lose a substantial portion of your revenue.
A single customer accounting for more than 15% of sales can make your business very unpredictable. The top five customers accounting for more than 25% of sales is also a significant risk. Dependence on a few major customers makes your business vulnerable.
Losing a major customer can lead to a sudden drop in revenue. This is a serious issue that can cause businesses to struggle or even fail. It's like having too many eggs in one basket, which sounds cliché but it's true in this case.
Prospering businesses maintain a diverse customer base to protect themselves from a potentially big loss from one client. By spreading your risk among multiple customers, the loss of one will not hit you as hard.
Measuring and Monitoring

Measuring and monitoring customer concentration risk is a crucial step in managing this risk. You can start by checking your sales report to identify the customer who earned you the most revenue in the last year.
A simple yet effective formula is to divide the sales from your largest customer by your total sales. For example, if your biggest client contributed $200,000 to your total yearly sales of $1,000,000, your customer concentration risk is 20%.
Regularly evaluating your customer concentration risk is essential, as risks can change over time based on shifts in your customer base and revenue distribution. Routine checks allow you to keep tabs on these changes.
To calculate customer concentration risk, you can follow these steps: Determine the revenue contribution per customer, divide the revenue contribution per customer by total revenue, convert the output from decimal notation to percentage form (multiply by 100), and perform sensitivity analysis (i.e., impact on revenue from the loss of a customer).

A customer concentration risk of 20% might be manageable, but if it reaches 40% or more, it could spell significant trouble. Industry concentration risk is another vital aspect to consider, as a large chunk of your profit coming from a single industry can lead to serious consequences.
Here's a simple way to check your customer concentration:
- Check your sales report to identify the customer who earned you the most revenue in the last year.
- Identify the amount of revenue that customer earned during that year.
- Divide that amount by your business's total revenue for that year.
- Multiply that number by 100 to complete the calculation.
Remember, the larger the concentration level, the more robust and advanced the analysis and risk management techniques should be.
Strategies for Handling
To handle customer concentration risk, it's crucial to diversify your customer base. This means seeking out a variety of clients of different sizes, rather than relying on one or a few big customers.
Focusing too much on big customers can backfire, as smaller clients may feel neglected and leave. This can leave your company depending too heavily on a few big accounts, giving them more bargaining power and potentially forcing you to lower prices and reduce profit margins.
Strategic planning and industry positioning are key to attracting a diverse range of customers. Analyze your market, understand the needs of different customer segments, and position your products or services to meet these needs. This can be a major benefit in reducing customer concentration risk.
Here are some strategies to help you get started:
- Diversification of Customer Base: Expand your customer base through targeted marketing, exploring new markets, and developing new products or services.
- Strengthening Relationships: Build strong, long-term relationships with existing customers to increase loyalty and reduce the risk of sudden revenue loss.
- Contractual Safeguards: Establish long-term contracts with key customers to provide revenue stability and reduce the risk of sudden customer loss.
- Liquidity: Maintain healthy cash reserves and diversify income streams to buffer against the financial impact of losing a major customer.
- Risk Management Practices: Periodically monitor customer concentration risk and implement contingency plans to prepare for potential disruption.
Rating System
A risk rating system is a crucial tool for managing concentration risk in your loan portfolio. It should be objective and sensitive to changes in borrower and/or loan characteristics.
Your risk rating system should be validated via an independent review function to ensure its accuracy. This review function is essential for maintaining a safe and sound business practice.
Examiners will review your documentation of the original and ongoing due diligence to ensure it's consistent with safe and sound business practices. This means keeping thorough records of your system's validation and review.
If you don't have an internal rating system, you shouldn't rely on the originating institution's system without completing timely and thorough due diligence. This due diligence is necessary to ensure the accuracy and reliability of the system.

Scenario and Sensitivity Analysis
Scenario and sensitivity analysis are crucial tools for credit unions to assess their portfolio's vulnerability to changing economic conditions.
Credit unions should perform these analyses on a routine basis to quantify the impact on asset quality, earnings, and net worth. They should also consider the susceptibility of portfolio segments with common risk characteristics to market fluctuations.
Examples of common risk characteristics include loan type, investment type, collateral type, geographic area, and individual or associational groups of borrowers. These characteristics can have a significant impact on a credit union's portfolio.
For instance, a concentration in HELOC mortgages can be particularly vulnerable to a rise in unemployment and a decline in house market values. This can lead to a significant risk to earnings due to interest rate resets and associated payment shock.
In contrast, a concentration in 30-year, fixed-rate mortgages may be more susceptible to liquidity and interest rate risks in a rising rate environment. This can cause earnings to deteriorate as members seek higher dividend rates to maintain their deposits.
The analyses should be multi-faceted to explore the effect of single and multiple simultaneous negative events on the portfolio. This will help credit unions to better prepare for potential risks and make informed decisions about their investments.

Strategies for Handling

Diversifying your customer base is key to reducing the impact of losing a single customer. This can be achieved by seeking out a variety of clients of different sizes and analyzing your market to understand the needs of different customer segments.
Strategic planning and industry positioning are crucial to attract a diverse range of customers. By positioning your products or services to meet the needs of different customer segments, you can increase your chances of attracting new customers and reducing your reliance on a few big accounts.
Having a high customer concentration can lower your company's value and make it harder to secure financing. This is because potential buyers or investors see customer concentration as a risk.
Don't rely on one or a few big customers. Instead, focus on building strong, long-term relationships with existing customers to increase loyalty and reduce the risk of sudden revenue loss.
To mitigate customer concentration risk, companies can employ several strategies, including:
- Diversification of Customer Base
- Strengthening Relationships
- Contractual Safeguards

Maintaining healthy cash reserves and diversifying income streams can help buffer against the financial impact of losing a major customer. This can provide a cushion against periods of underperformance.
Professional advice can be invaluable when dealing with businesses with high customer concentration. Industry experts can offer valuable insights into how to mitigate risks associated with customer concentration and guide you through the intricacies of managing these risks.
A well-prepared transition plan can be a lifesaver when it comes to maintaining customer relationships post-purchase. This can ensure that key customers stay on board even after the business changes hands.
