What each customer cost before tripwire revenue
150 tripwire buyers × ₹499 × 60% margin
Real cost per customer after tripwire revenue
Backend profit + tripwire profit − ad cost
(Tripwire + backend revenue) ÷ ad spend
Tripwire isn't pulling its weight. Either it's too cheap, take-rate is low, or margin is thin. Either fix the offer or treat ads as standalone profit math.
