Customer and supplier concentration refers to how much a business relies on a limited number of clients or vendors. High concentration can create financial and operational risks. Understanding the related metrics and applying diversification strategies helps in maintaining business stability.
The Customer Concentration Ratio assesses how much of a company’s total revenue depends on its major customers. A high ratio indicates that a few clients generate a significant portion of total sales — a sign of potential vulnerability if any of them reduce or terminate their relationship.
For example, if a manufacturer earns 60% of its revenue from its main three customers, a single contract loss could heavily impact operations and cash flow. In contrast, a lower ratio suggests a more stable and diversified revenue base.
Key insight:
Customer concentration doesn’t always signal weakness — in niche B2B markets, strong, long-term partnerships with major clients can ensure consistent revenues. However, dependency should be balanced with diversification to safeguard financial health.
The Supplier Concentration Ratio measures reliance on a limited number of suppliers for key inputs, raw materials, or services. A high ratio implies operational risk — disruptions from one supplier could halt production or raise costs.
For instance, an electronics firm sourcing 70% of its components from a single vendor faces high exposure to that supplier’s pricing, delivery, and financial stability.
Why it matters:
A diversified supplier network enhances supply chain resilience, reduces negotiation pressure, and helps maintain stable production even in volatile market conditions.
These ratios quantify how concentrated or diversified a company’s customer and supplier bases are:
Customer Concentration Ratio = (Revenue from Major N Customers ÷ Total Revenue) × 100
Supplier Concentration Ratio = (Purchases from Major N Suppliers ÷ Total Purchases) × 100
Example:
If your top five customers account for ₹80 crore of your ₹200 crore total revenue,
then Customer Concentration = (80 ÷ 200) × 100 = 40%.
A concentration above 40–50% often signals elevated risk, though acceptable levels vary by industry.
Interpretation:
A lower ratio implies healthy diversification. However, companies must evaluate these ratios alongside industry norms — in sectors like defense or aviation, working with a few strategic partners is common.
Supplier metrics often go beyond simple percentages. Analysts track:
Major 5 Supplier Share (% of total purchases)
Dependency Index (weighted by criticality and availability)
Geographic Spread (domestic vs international sourcing)
These indicators help identify potential bottlenecks in procurement, cost volatility, or exposure to geopolitical risks. Companies with balanced sourcing strategies tend to achieve stronger operational continuity and negotiating leverage.
Customer diversification is a critical risk management strategy. Relying heavily on a few large customers can lead to revenue volatility, delayed payments, and reduced bargaining power.
A well-diversified base spreads business risk, improves creditworthiness, and attracts investors who value predictable cash flows. It also enhances business resilience during economic downturns or market shifts.
Benefits of customer diversification:
Stabilises revenue and cash flow
Reduces exposure to client-specific risks
Strengthens negotiation power in pricing
Improves brand perception and market reach
Building a balanced portfolio of customers and suppliers is key to long-term sustainability. The process requires proactive expansion and relationship management:
Explore new markets, industries, or regions to reduce reliance on existing clients. For example, an Indian exporter heavily dependent on the U.S. could expand into Southeast Asia to hedge against regional slowdowns.
Use multi-sourcing to secure alternate suppliers for critical inputs. Establish long-term contracts and performance clauses to ensure quality and delivery reliability.
Maintain consistent communication with major customers and suppliers. Collaborative forecasting and joint planning improve transparency and reduce surprises.
Track delivery timelines, defect rates, and pricing stability to identify potential risks early. Diversify before a single supplier becomes irreplaceable.
Use CRM and ERP tools to monitor revenue concentration trends and simulate “loss of major customer” scenarios for stress testing.
The Customer & Supplier Concentration Ratios provide vital insight into a company’s financial resilience, operational stability, and creditworthiness.
A business with balanced relationships is equipped to navigate disruptions and maintain steady performance.
Key takeaways:
A high concentration ratio signals dependency risk, while moderate ratios suggest balance.
Diversification enhances liquidity, valuation stability, and long-term competitiveness.
Regular monitoring of concentration trends helps anticipate potential threats before they materialize.
Strategic supplier and customer management fosters sustainability and investor confidence.

Supplier concentration is measured using the formula (Purchases from Major N Suppliers ÷ Total Purchases) × 100. It indicates how much a company’s procurement depends on a small group of suppliers, highlighting potential supply chain risks.
High customer or supplier concentration increases both operational and credit risk. It can lead to tighter lending terms, lower credit ratings, and reduced market valuation, as dependency on a few counterparties raises vulnerability to disruptions.
Efficiency and diversification must be balanced to manage risk without raising costs excessively. A well-diversified business can maintain flexibility and resilience while still benefiting from economies of scale in procurement and operations.
A business is typically viewed as highly concentrated if more than 50% of its revenue or purchases come from its main three customers or suppliers. Such dependency increases exposure to financial or operational instability if any key partner fails.
Technology can support concentration risk management by using analytics to detect dependency spikes, automate supplier evaluations, and simulate potential disruptions. These tools enable early intervention and enhanced strategic planning for supply continuity.
