What is Revenue Concentration?

Revenue concentration measures how much of your total revenue depends on one client. If Client A represents 45% of monthly revenue, your concentration for that client is 45%.

High concentration is common in early-stage businesses but creates fragility. A delayed payment, churned contract, or renegotiated deal from a large client can destabilize payroll and runway overnight.

Concentration risk is nonlinear. Moving from 20% to 40% concentration more than doubles your exposure. Above 50%, a single client delay can threaten operations regardless of overall profitability.

Why it matters

Profitable businesses fail when one large client pays late or leaves. Concentration risk does not appear on a standard P&L until the problem arrives.

Tracking concentration per client lets you diversify proactively, set internal payment alerts, and negotiate terms before dependency becomes existential.

Example

Three clients generate $80K monthly revenue: Client A $44K (55%), Client B $24K (30%), Client C $12K (15%). Client A pays Net-45 but historically takes 58 days. A two-week delay on Client A alone threatens payroll.
