Flat commissions ignore the one metric that matters: partner-sourced LTV

A recurring partner-program failure is paying every partner the same percentage regardless of the lifetime value they bring. Two partners can both deliver a $1,000 first-month contract; one cohort churns at 4% monthly and the other at 1%. The flat model pays them identically while their actual contribution to the book differs by multiples.

The mechanics:
— Partner channels vary enormously in downstream retention. Integration and ecosystem partners tend to produce stickier accounts (the switching cost of an embedded integration is real).
— Content and coupon partners often skew toward price-sensitive buyers with higher churn.

The fix — tier on cohort quality, not gross volume:
— Track partner-sourced cohorts separately and compute retained revenue at month 12, not signups.
— Introduce a quality multiplier: a clawback on early churn plus a loyalty bonus on accounts retained past the payback period.
— Use net revenue retention by partner as the headline KPI, not new logos.

Caveat: small partners produce noisy cohorts. Require a minimum sample (often 30+ accounts) before applying multipliers, or you will penalize variance, not quality.

Implications: a program optimized for signup volume and a program optimized for retained value will, within a year, recruit visibly different partner rosters.
