Your highest-billing client generates 4 percent of your profit
Revenue per client tells you almost nothing. Profit per client tells you which relationships to grow and which to walk away from.
Most owners chase revenue. The clients who pay the most often demand the most support, the most rework, and the most unbilled hours. Profit per client is the number that tells the truth.
What this looks like
Sarah runs a boutique consultancy. Her largest client billed 180,000 a year — more than any other. When she switched to the Customer Profitability view in Incremenza, she saw their actual profit contribution was 7,200. Hidden under that number: 340 hours of unbilled support, scope creep across three engagements, and a pricing structure she had not updated since 2022. She repriced the contract. The client agreed to a 38 percent rate increase. Composite scenario based on common patterns.
