Customer concentration

The /reports/customer-concentration endpoint analyzes revenue concentration across your customer base. It shows how MRR is distributed among your top customers (Pareto analysis), helping identify revenue concentration risk.

💡 Use case: Assess revenue concentration risk, identify your most valuable customers, understand if you're over-dependent on a few large accounts.

GET /reports/customer-concentration

Returns Pareto analysis of revenue distribution and concentration metrics.

Notes

Currency values: All monetary values are returned in cents/smallest currency unit. Divide by 100 for display in most currencies.

Pareto principle: Typically 80% of revenue comes from 20% of customers
Top 10 detail: The top 10 customers are listed individually, then grouped (11-20, 21-50, etc.)
Concentration risk: High concentration (e.g., top 5 customers = 50%+ of MRR) indicates risk
Median vs average: Large difference suggests high concentration
Use cases: Investor due diligence, risk assessment, account management prioritization
