# BillingTotals

> Billing regularly introduces new features and UI changes to Clerk's components. If you'd like to remain on a specific version of Clerk's components or SDK, you can follow the steps in the [pinning](https://clerk.com/docs/pinning.md?sdk=vue) documentation.

The `BillingTotals` type represents a granular breakdown of the total amount that will be charged, either during
checkout or at renewal.
