# Apply Current Plan Terms

Move a subscriber onto the plan's current price and cadence.

Subscriptions bill from the terms captured when they started, so repricing a
plan never moves an existing subscriber. This is the only way a repricing
reaches someone already subscribed, and it is always deliberate.

The new terms take effect **from the next period**. The period they have
already paid for is left alone.

<Note>
  If the cadence changed, the billing cycle re-anchors at the current period end.
  A subscriber moved from monthly to annual bills a year after their current
  period ends.
