Pricing Mechanics
Margin Leakage
The gradual, often invisible erosion of project profitability caused by underpricing, scope creep, uncontrolled discounts, and inefficient delivery — typically amounting to 15-25% of annual margin.
Definition
Margin leakage is the gap between the margin a firm should achieve based on its rates and the margin it actually realizes. PMI's Pulse of the Profession 2024 found that 52% of projects experience scope creep with an average 27% cost overrun. Ignition's 2025 survey reported that 57% of agencies lose between €1k and €5k per month specifically to unbilled scope creep work.
There are four primary sources of margin leakage: (1) pricing leakage — setting prices too low relative to delivered value; (2) scope leakage — delivering work beyond the agreed scope without billing for it; (3) discount leakage — unsystematic discounting that erodes average deal value; and (4) delivery leakage — inefficient processes that consume more hours than estimated.
Margin leakage compounds invisibly. A firm that loses 2% per month across all four sources is losing approximately 22% of annual margin — without any single event being large enough to trigger an alarm. Pricing architecture audits exist to make these leaks visible and quantifiable.

Hourly Rate Trap
The structural limitation where billing by the hour caps a firm's revenue at the number of billable hours available, creating an implicit ceiling on income regardless of value delivered.
