 We have two versions of the New Relic One pricing model: 
 
-* **Our primary New Relic One pricing version.** This version is also known as "New Relic One with core users." It was released January 12, 2022. Organizations on this version have access to a third user type: the [core user](/docs/accounts/accounts-billing/new-relic-one-user-management/user-type), and their [billable user rules](#user-count) are different than the "New Relic One without core users" version's rules.
-* **The "New Relic One without core users" version.** If your New Relic organization existed prior to January 12, 2022, and hasn't switched to the newer version, this is your version. Organizations on this version can add only basic users and full platform users; they don't have access to core users. This pricing version will be increasingly deprecated over time. See the [billable user rules for this version](#non-core).

 Tips for determining which version you're on: 
 * If your organization has core users or has the ability to add core users, you're on our primary version. If you can only add basic users and full platform users, you're on the "New Relic One without core users" version. You can view your users by going to the [**User management** UI](/docs/accounts/accounts-billing/new-relic-one-user-management/user-management-ui-and-tasks/#where). 
 * Another way to determine your version is by going to the [**Manage your plan** UI](/docs/accounts/accounts-billing/new-relic-one-pricing-billing/billing-ui). If you see "New Relic One - Users", that means you're on the "New Relic One without core users" version.  
 
 For more about the differences between these versions, see [Core users release](/docs/accounts/accounts-billing/new-relic-one-pricing-billing/core-users-release).

 To determine an organization's count of billable users in a calendar month, we count the users during that month who had a **billable user type** of either full platform user or core user. A user’s **billable user type** is defined as the highest user type at which a user was set during a calendar month. We use UTC timezone to define the start and end of a calendar month. 
 
 For an example of how this works in practice: If a user is set as a full platform user at any point during a calendar month, their billable user type for that month is "full platform user," and won't change, even if they downgrade later that month. This is the case even if that user is changed to a full platform user only briefly.

 When a New Relic organization first starts being billed, their billable user count is pro-rated based on when during the month they started. If an organization cancels their subscription, prorating is also applied for their last month.

-The following rules apply only for organizations on the [version of New Relic One pricing without core users](#pricing-versions): 
-
 * **How billable users are determined.** For a calendar month, an organization is billed based on a calculation of the number of full platform users for that month. 
 * **Prorating in first and last month.** The count of billable users is prorated based on when a New Relic organization starts their subscription, or based on when a user becomes a full platform user (added as a full platform user or converted to one).
 * **Users are billable when provisioned.** A user counts as billable the moment they are set to a billable user type in New Relic. This applies regardless of whether that user has ever logged into or used New Relic. 
 * **User count based on email address.** If there are multiple user records in an organization that have the same email address, for billing purposes that would count as a single user.
 * **Caveat for our original user model.** If your organization has users on our [original user model](/docs/accounts/original-accounts-billing/original-users-roles/overview-user-models): If a user is set as a basic user in one account in the organization and as a billable user in another account, the billable user status takes precedence.
