# Backend BillingPlan object > 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) your SDK and `clerk-js` package versions. The `BillingPlan` object is similar to the [BillingPlanResource](https://clerk.com/docs/reference/types/billing-plan-resource.md) object as it holds information about a Plan, as well as methods for managing it. However, the `BillingPlan` object is different in that it is used in the [Backend API](https://clerk.com/docs/reference/backend-api/tag/billing/GET/billing/plans){{ target: '_blank' }} and is not directly accessible from the Frontend API. ## Properties | Name | Type | Description | | ---------------- | -------------------------- | -------------------------------------------------------------- | | id | string | The unique identifier for the Plan. | | name | string | The Plan's name. | | slug | string | The URL-friendly identifier of the Plan. | | description | string | null | The Plan's description. | | isDefault | boolean | Whether the Plan is the default Plan. | | isRecurring | boolean | Whether the Plan is recurring. | | hasBaseFee | boolean | Whether the Plan has a base fee. | | publiclyVisible | boolean | Whether the Plan is displayed in the component. | | fee | BillingMoneyAmount | null | The monthly fee. | | annualFee | BillingMoneyAmount | null | The annual fee. | | annualMonthlyFee | BillingMoneyAmount | null | The annual fee on a monthly basis. | | forPayerType | 'user' | 'org' | The type of payer. | | features | Feature[] | The Features the Plan offers. | | avatarUrl | string | null | The URL of the Plan's avatar image. | | freeTrialDays | number | null | The number of free trial days. | | freeTrialEnabled | boolean | Whether free trial is enabled. | --- ## Sitemap [Overview of all docs pages](https://clerk.com/docs/llms.txt)
