Contingent agencies are the right starting point: no fixed cost, immediate reach, pay on success. But the model has a ceiling. Past a certain volume, the per-hire cost and quality variance eat the savings. This is the guide for spotting that ceiling before it costs you a quarter of growth.
Signal 1: Your Hiring Is Steady, Not Spiky
Contingent agencies are built for unpredictable, spiky hiring. The success-only fee funds their availability. When your hiring becomes steady, say ten or more hires per quarter consistently, you are paying the spike premium on volume where a fixed-cost model would be cheaper. The break-even shifts past roughly fifteen hires a year.
Signal 2: Cost Per Hire Is Climbing
Agency fees compound fast at volume. Five hires at 20% of ₹40L is ₹40L in fees. Twenty hires is ₹160L. An embedded RPO running at a monthly retainer can deliver those twenty hires at a fraction. When you run the math and the RPO option is cheaper at your current volume, the signal is already there.
