# trial.converted

> Fired when a trialing customer converts to a paid subscription before the trial ends.

## When this fires

A customer on a trial changes plan before the trial runs out. The trial ends immediately, the full new plan price is charged (no proration credit — trials are free), and the subscription becomes `active`.

`subscription.plan_changed` fires alongside this event with the charge details. Use `trial.converted` for conversion analytics and lifecycle messaging; use `subscription.plan_changed` for entitlement updates.

Trials that simply run out fire `trial.expired` instead — that is the natural trial-to-paid transition.
