# BillingSubscriptionItemResource

> Billing is currently in Beta and its APIs are experimental and may undergo breaking changes. To mitigate potential disruptions, we recommend [pinning](https://clerk.com/docs/pinning.md?sdk=expo) your SDK and `clerk-js` package versions.

The `BillingSubscriptionItemResource` type represents an item in a subscription.
