Put one or more locations on a plan partway through a billing period, charged pro rata for the remainder. The locations are on the plan from now until the end of the month; the first charge is prorated and applied to next month's invoice. Each location's previous plan is closed, and the plan also becomes the plan of the account the locations belong to.

Prerequisites: the locations' ids (store_ids) and a plan_id set up for your partner.

Authentication: Partner or Account token. plan_id must be one of your partner's plans, and every location must be inside your own account tree; otherwise 422.

Rate limit: none.
