The billing anchor is now its own field. In Manage Plan, the Billing period section shows the interval and an editable next reset date. Editing it moves every future renewal, usage reset, and credit grant, and the subscription preview itemizes the proration: remaining time on the base fee, seats paid in advance, and credits granted for the partial period, counted in credits rather than dollars.

Custom plan finalization has the same control. Anchor to the activation date, or pick a custom date so the first period runs from activation to the anchor with a prorated first invoice. Deals that need co-terming or a calendar renewal date, such as renewing on January 1, no longer need a workaround.

The company's Subscription tab shows the anchor read-only. Everything here is available through the API, including the proration preview.
