# Plan changes and overage

How upgrades, downgrades, proration and overage billing work

Owners and the Billing role can upgrade from the Billing page. Downgrading to Free is Owner only. Three rules govern every change:

* Upgrades take effect immediately on successful payment. Downgrades take effect at the start of the next billing cycle.
* Charges are prorated, allowances are not. On upgrade you get the full new plan allowance, with usage already consumed carried over.
* A Free to paid upgrade resets the billing cycle to the upgrade date. A paid to paid change keeps your existing billing date.

### Upgrading

**From Free.** You are charged the full plan price, your billing cycle restarts on the upgrade date, the usage counter resets to zero and all new limits apply immediately.

**From Growth to Pro.** You are charged the prorated difference for the days remaining in the cycle, and your billing date stays the same. Usage consumed so far carries over and counts against the new 1.5B allowance. Any overage already accrued on Growth is billed at the Growth rate on the upgrade invoice.

Example: Your cycle runs 1 to 31 July, you have used 380M CU on Growth and upgrade to Pro on 17 July.

<table><thead><tr><th width="549.76953125">Line</th><th>Amount</th></tr></thead><tbody><tr><td>Pro, 17 to 31 July ($199 x 15/31)</td><td>$96.29</td></tr><tr><td>Credit for unused Growth ($49 x 15/31)</td><td>-$23.71</td></tr><tr><td>Overage under Growth (80M x $0.35 per 1M)</td><td>$28.00</td></tr><tr><td>Charged on 17 July</td><td>$100.58</td></tr></tbody></table>

After the upgrade, 1,120M CU of the Pro allowance remains for the cycle, and $199 is charged on the usual billing date for the next cycle.

### Downgrading

A downgrade is scheduled for your next cycle boundary and can be cancelled any time before then. Until the boundary you keep full current plan access. A reminder email arrives one day before it takes effect.

* If your active apps exceed the target plan's limit at the boundary, all endpoints suspend until you disable enough apps. Nothing is deleted; you choose what to keep.
* On a downgrade to Free, members other than the Owner are frozen and teams and alerts are deactivated. Everything is preserved and restored if you upgrade again.

### Overage billing

On Growth and Pro, usage beyond your monthly allowance is billed at your plan's overage rate on the invoice issued at the end of the cycle. Your renewal invoice therefore shows the next cycle's subscription in advance and the finished cycle's overage in arrears, each labeled with the period it covers. Set an [overage alert](/rpc/platform-guide/alerts.md) to hear about it before the invoice does.

### If a payment fails

Nothing changes on the day a payment fails: endpoints keep running and everyone keeps access. The Owner, Admins and Billing are emailed, with a reminder and a dashboard banner on day 3.

If the payment is still unresolved after 7 days, the organization locks: endpoints stop, members other than the Owner and Billing lose access, and everything is preserved. Paying the outstanding invoice restores service immediately, with no reconfiguration needed.
