<b>Do partner-sourced customers retain better? The NRR question</b>

Net revenue retention (NRR) — expansion minus churn on an existing cohort — is the metric SaaS investors weight most heavily. A persistent question in channel research: do partner-sourced customers retain differently from direct-sourced ones?

<b>The case for better retention.</b> Partners — especially implementation and reseller partners — provide ongoing service that increases switching costs and product adoption. Per several vendor disclosures, partner-attached accounts often show NRR several points above direct accounts, attributed to deeper integration and a local relationship that absorbs friction.

<b>The selection-bias counterargument.</b> Partners may simply select better-fit customers, or larger accounts that retain better regardless of source. The retention difference could reflect who partners choose, not what partners do. Without random assignment — which no program runs — causation stays unproven.

<b>The churn-risk concentration.</b> A countervailing risk: if the partner relationship sours or the partner churns, the end customer may follow. Partner-attached retention can be higher in steady state but more correlated in failure — a fat-tail risk single-vendor NRR figures hide.

<b>Trade-off:</b> partner attachment buys retention at the cost of concentration risk and a margin share that lowers per-account profitability even as it raises lifetime value.

<b>Open questions:</b> is the NRR premium a service effect or a selection effect? Resolving it would require comparing partner and direct cohorts matched on size and fit — an analysis most programs have the data for but rarely run.
