## Billing

**What are AI credits?**

Credits are how Wonderly measures AI usage. They are only consumed when AI takes an action. Using the other features available in your Wonderly account won't consume any AI credits.

Credits are granted upfront at the start of each billing period. On a monthly plan, you receive 10,000 credits at the start of every month. On an annual plan, you receive 120,000 credits upfront for the full year.

Unused credits do not carry over. At the start of each new billing period, your allocation resets to the corresponding amount for your plan. Any credits left from the previous period are not transferred.

For most service businesses, 10,000 credits a month is enough to cover day-to-day AI activity.
