Seat management is currently available to Owners and Primary Owners of Enterprise plans on annual invoiced contracts.
As an Enterprise plan customer on an annual invoiced contract, you can flexibly manage and add seats to your organization beyond your initial contract allocation. This article explains how seat and member management works, including what to expect regarding billing, with single sign-on configured.
If your organization hasn’t configured SSO yet, see Setting up Single Sign-On on the Enterprise plan.
If you’re managing members and seats on an Enterprise organization without SSO, see Managing members and seats on Team and Enterprise plans (without SSO enabled).
Understanding Seat Management
You can add seats beyond your initial contract allocation at any time.
New seats are billed at your contract's existing per-user price.
While seats cannot be removed from your total allocation, you can reassign them to different team members.
You can upgrade standard seats to premium seats, which include access to Claude Code and increased usage limits.
How Billing Works
You'll receive an invoice immediately when new seats are added.
Each new seat is prorated for the remainder of your annual term.
For auto-renewal contracts, your renewal will include the total number of seats in use at the end of your term.
How to add seats
Log in to your Owner or Primary Owner account.
Go to your Billing Settings.
Click the pencil icon under Seats.
Make any necessary seat increases or upgrades.
Review your increase carefully before confirming your purchase.
Click "Upgrade" to finalize your changes.
Seat Types
Owners and Primary Owners can purchase two different types of seats to allocate to organization members:
Standard seats include all the core Enterprise plan features.
Premium seats include the core features mentioned above, as well as access to Claude Code and more usage.
Billing Example
Here's how billing works when adding seats:
If you start with 100 standard seats on January 1 and:
Add five more standard seats on March 1.
Upgrade 10 standard seats to premium seats on March 1.
You will receive an invoice immediately for:
The five additional standard seats (billed for 10 months remaining in the term).
The 10 seat upgrades from standard to premium (billed for the difference per seat for 10 months remaining).
How do I add a member to my team?
This depends on your organization’s provisioning method; the process is different for manual, Just-in-Time, and SCIM.
Manual
Admins and above can follow these steps to add members to an Enterprise organization:
Navigate to Settings > Members and click “Add member."
Enter the person’s email address (it must use one of your organization’s verified domains) and set the role and permissions for the member.
This will send an email to the person inviting them to join the team.
This email invitation will expire after 21 days, so you will need to re-invite the member if they don't use the invitation within that time period.
Note: When the Anthropic team provisions an Enterprise organization and invites the Primary Owner, the 21-day expiration period applies to that initial invitation.
JIT and SCIM
Note: An Owner or Primary Owner must add seats before new users can sign in via SSO. We recommend monitoring your seat usage and adding seats proactively to ensure uninterrupted access for your team.
Just in time (JIT): Members assigned to your organization’s Anthropic Identity Provider app will have accounts created for them the first time they log in using the assigned email address. Note that JIT provisioning requires you to have unclaimed seats available to add new users. At this time, it’s not possible to assign seat tiers using JIT with Advanced Group Mappings. Provisioning users with JIT will automatically allocate unclaimed seat tiers to them as they log in, so Admins and above can manually reallocate seats in Settings > Members.
SCIM: Members assigned to your organization’s Anthropic Identity Provider app will have accounts created automatically. Note that SCIM provisioning requires you to have unclaimed seats available for new user addition. At this time, it’s not possible to assign seat tiers using SCIM with Advanced Group Mappings. Provisioning users via this method will automatically allocate seat tiers, so Admins and above can manually reallocate seats in Settings > Members if needed.
