Charges the prorated difference for the remainder of the current period, moves every site the subscription entitles, and supersedes the subscription onto the new plan version — keeping the existing period window, so the customer's renewal date does not move and they are not handed a free extra period. ⛔ A plan change SUPERSEDES rather than mutates, because a subscription pins the exact version it was sold so that a later catalogue edit cannot rewrite what a live subscriber pays. subscription_id in the response is therefore a new id and a client holding the old one must replace it. ⭐⭐ slots_before and slots_after are read back from the subscription rows, not derived from the plan that was asked for. A plan change that answers 200 and silently does not take effect is the worst outcome on this path, and a status code cannot tell that apart from one that worked. Mid-period money. A larger plan is charged the difference now — the customer asked for more room today, and applying it at the next renewal is the buy-flow dead end in another costume. A smaller plan returns the unused difference as account credit, not a card refund: it is instant, it cannot be unavailable, it is idempotent, and it is spendable on their next order. ⛔ Account credit carries no VAT credit note; a proration credit spans the current period's invoice rather than reversing it. ⛔ expected_total_minor is a money guard, not a convenience. It is the figure the customer was actually shown, and the change is refused 422 when the freshly-computed quote differs. Every other refusal is 422 as well, with nothing charged and nothing changed: a plan on another product line, the plan they are already on, a plan that has been re-priced since the page loaded, account usage above what a smaller plan allows, a card decline. ⛔ The downgrade guard is account-wide and there is no override. The same check_downgrade the site endpoint and the staff tariff endpoint call: sites, mailboxes, mailbox storage and disk across the org's subtree. Staff have an audited override because they sometimes genuinely need to move an over-limit account; a customer overriding their own quota check is not an override, it is no check. Repeating an identical request is the recovery and it is safe. Every step is idempotent on a key anchored to the subscription being left, so an attempt that died part-way is finished rather than duplicated: one order, one charge, one credit, one supersede. 404 for a subscription in another tenant as well as for one that does not exist. 503 when the driver behind an entitled site cannot move a package between types at all — our gap, not theirs. Requires billing.payment.manage — it charges a card, so the key that gates paying is the key that gates committing to a payment.
