## **Credit Rollover & Top-Ups**

Eligible subscribers can carry unused monthly credits into the next billing period instead of losing them at renewal.

**Eligibility**<br />Rollover is available on Basic and above (Basic, Max, Scale, Scale2x, Scale4x, Business, Teams).

**How it works**<br />Your total credit balance is capped at **3× your monthly allowance**(current month + up to 2× in rollover).Changes to you plan may impact existing credits.

* **Downgrade:** Balance is immediately reduced to the new plan’s cap. Any excess credits are forfeited.
* **Upgrade:** No change to existing credits.
* **Cancellation:** All remaining credits are forfeited at the end of the billing period.

Top-up credits (available only to existing Teams/Business customers and Scale 4x users) carry over if unused.

## How to Get More Credits

Individual credit top-ups are not available for standard plans. Your options are:

* **Upgrade your plan** — Moving to the next plan level increases your monthly credit allotment
* **View your current usage** — Go to **Account Settings** to see how many credits you've used and how many remain
* **View credits history (iOS)** — On iOS, you can view a detailed history of your credits usage to see exactly how your credits have been spent
