Concentration Risk: 3 Customers = 40% of Revenue (Fragile Business)
B2B manufacturer SGD 10M annual revenue: top 3 customers = SGD 4M (40%). Lose 1 customer = SGD 3.33M revenue, -10% impact. Business at risk if customer consolidates (merger, relocation) or disputes. Concentration risk: unacceptable. Target: top 3 customers <30% of revenue (each <10%). Action: identify 10 similar-size new customers over 2 years, grow revenue from SGD 10M to SGD 15M such that top 3 = 30% of new base. Reduce risk, smoother growth.
Measuring Concentration#
Calculate % of revenue from top N customers. If top 3 = 40% of revenue, concentration risk high. If top 10 = 60% of revenue, concentration moderate. If top 20 = 70% of revenue, concentration low (healthy). Rule: no single customer >15% of revenue, no top 3 >40%, no top 5 >60%.
Why Concentration Matters#
(1) Lose major customer = crisis (10-20% revenue drop overnight). (2) Customer negotiation power: "Give me 20% discount or I leave" = you must accept (can't afford to lose them). (3) Valuation: acquirer of concentrated business discounts valuation (higher risk).
(1) Identify ideal customer profile (size, industry, margin).
De-Concentration Strategy#
(1) Identify ideal customer profile (size, industry, margin). (2) Target similar-size new customers (avoid mega-customers that become concentrated again). (3) Grow revenue such that each customer represents smaller %: if top customer = 15% of current SGD 10M = SGD 1.5M. If you grow revenue to SGD 20M without losing customer, customer = 7.5% (better diversified). (4) Gradual: 2-3 year de-concentration target.

AskBiz Concentration Analysis#
Tracks revenue by customer, identifies concentration. "Top 3 customers: 40% of revenue (red flag). Top 10: 65% (moderate). Gini coefficient: 0.65 (high inequality). Industry benchmark: 0.40 (lower concentration = healthier). Target: reduce to 0.45 over 2 years. Strategy: grow revenue 50% (current SGD 10M → SGD 15M) while maintaining top 3 customers. Top 3 will drop to 27% of new revenue (healthier). New customer acquisition: 10 medium-size customers (SGD 0.5M each) = SGD 5M new revenue."

People also ask
Should I refuse large customer to avoid concentration?
Not entirely. Accept 1-2 large customers (say 15% each), but ensure top 3 don't exceed 40%. Balance: growth (take large customers) + stability (diversify ongoing).
How do I retain large customers while growing others?
Don't raise prices on them (keep loyal). Invest in relationship (dedicated account manager). Diversify their buying (sell more product types). Make them sticky (integration, switching cost).
