How to automate Carta user provisioning, and what it actually costs

Summary and recommendation

Carta offers SCIM provisioning, but only through their Okta connector and requires the Scale plan (starting at $67,200-$112,000/year for 500+ stakeholders). While Okta integration supports Group Linking, Schema Discovery, and Attribute Writeback, this leaves organizations using other identity providers like Entra ID, Google Workspace, or OneLogin without native provisioning options. For a platform managing highly sensitive equity data across finance teams, legal, executives, HR, and employees, this creates a significant gap in user lifecycle automation.

The enterprise pricing barrier compounds the problem. Most growing companies need SCIM automation well before they reach the Scale plan's stakeholder thresholds, yet they're forced to manually manage user provisioning for one of their most security-critical applications. This manual process increases the risk of orphaned accounts with access to confidential cap table data and creates administrative overhead for IT teams managing role-based access that varies by vesting schedules and equity positions.

The strategic alternative

Carta has no native SCIM. Automate offboarding, user access reviews, and license workflows across every app, including the ones without APIs. We maintain the integration layer underneath. You focus on judgment, not plumbing.

The cost of not automating

Without SCIM (or an alternative like Stitchflow), your IT team manages Carta accounts manually. Here's what that costs:

The Carta pricing problem

Carta gates SCIM provisioning behind premium plans, forcing significant cost increases for basic user management.

What this means in practice

For a company with 100 stakeholders on Growth ($16,000/year), adding SSO requires upgrading to Scale at $67,200/year minimum - a 320% price increase just to enable basic identity management.

The stakeholder threshold creates an artificial floor: even if you only need SSO for 10 administrators, you're paying for 500+ stakeholder capacity because that's where SSO becomes available.

Additional constraints

Okta dependency
SCIM provisioning only works through Okta's connector, leaving Entra ID and Google Workspace users without automated provisioning
Enterprise sales requirement
Scale and Enterprise plans require contacting Carta's sales team - no self-service upgrade path
No transparent Enterprise pricing
Custom pricing means lengthy negotiations for larger deployments
Multi-year commitment pressure
Discounts (8-15%) only available on 3-year terms, increasing total commitment

Summary of challenges

  • Carta does not provide native SCIM at any price tier
  • Organizations must rely on third-party tools or manual provisioning
  • Our research shows teams manually provisioning this app spend significant hidden costs annually

What Carta actually offers for identity

SAML SSO (Scale plan required)

Carta supports federated SSO starting at the Scale plan ($67,200-$112,000/year):

ProtocolSAML 2.0, OIDC
Supported IdPsOkta, Azure AD, Rippling, generic SAML/OIDC
JIT Provisioning✓ Yes

Update users✓ Yes
Deactivate users✓ Yes
Group push✓ Yes (Group Linking)
Attribute writeback✓ Yes

Major limitation: SCIM provisioning only works with Okta. Teams using Azure AD, Google Workspace, or OneLogin get SSO but no automated provisioning.

What's missing for multi-IdP environments

The Scale plan pricing ($67K-$112K annually) includes extensive equity management features like 409A valuations, advanced reporting, and multi-entity support. For IT teams that simply need SCIM across multiple identity providers, roughly 90% of these features are irrelevant to access management needs.

More critically, Carta's SCIM connector only works with Okta, leaving Azure AD and Google Workspace customers without automated user lifecycle management despite paying enterprise-tier pricing.

What IT admins are saying

Community sentiment on Carta's provisioning reveals frustration with plan restrictions and limited automation:

  • Scale plan required for SSO, forcing costly upgrades just for basic identity features
  • SCIM provisioning only available through Okta connector, excluding other identity providers
  • Enterprise features require custom pricing conversations with no transparent costs
  • Manual user management persists despite premium pricing

Enterprise pricing not transparent

Community feedback on Vendr, reflecting the common complaint about Carta's opaque enterprise pricing model that forces lengthy sales conversations for SCIM capabilities.

The recurring theme

Carta gates essential identity management features behind expensive plans, forcing organizations to pay $67K+ annually or manage users manually. Even then, SCIM provisioning is limited to Okta users only.

The decision

Your SituationRecommendation
Small startup (<25 stakeholders)Manual management acceptable on Launch plan
Growing company with basic SSO needsUpgrade to Scale plan for native SSO
Enterprise using Okta for provisioningUse Okta's SCIM connector if already invested
Multi-IdP environment or non-Okta usersUse Stitchflow: works with any IdP at predictable cost
Scale plan budget concerns ($67K+ annually)Use Stitchflow: build complete workflows across every app in less than a week (~2 hours of your time).

The bottom line

Carta offers SCIM provisioning through Okta's connector, but only after committing to their expensive Scale plan ($67K+ annually). For equity management teams that need provisioning automation without the hefty price tag or Okta lock-in, Stitchflow delivers the same automation capabilities at a fraction of the cost.

B2B Revenue Intelligence / ABM

ProvisioningNot Supported
Manual Cost$11,754/yr

6sense, the B2B revenue intelligence platform, has paused SCIM provisioning for new customers until Q4 2026. While existing customers with SCIM enabled can continue using it, new implementations are limited to JIT (Just-In-Time) provisioning through SAML SSO. This creates a significant gap for IT teams managing revenue intelligence access, as JIT only creates users on first login and provides minimal attribute mapping (email, first name, last name only). For an enterprise platform with typical pricing of $55,000-$130,000 annually, the absence of automated user lifecycle management is a substantial limitation. The lack of SCIM until Q4 2026 forces IT teams into manual provisioning workflows for a platform handling sensitive revenue data. While SAML SSO handles authentication, it doesn't address user lifecycle events like role changes, department transfers, or offboarding. This creates compliance risks in revenue teams where access to prospect data and sales intelligence must be tightly controlled. The nearly two-year wait for SCIM restoration means organizations implementing 6sense today face manual user management for the foreseeable future.

ActiveCampaign

No SCIM

Marketing Automation / Email

ProvisioningNot Supported
Manual Cost$11,754/yr

ActiveCampaign, the marketing automation platform, does not offer native SCIM provisioning on any plan. While the Enterprise plan ($145+/month) includes SAML 2.0 SSO with just-in-time (JIT) provisioning, this only creates user accounts on first login—there's no automated deprovisioning when employees leave or change roles. New SSO users are automatically added to a generic "SSO Users" group with configurable permissions, but IT teams have no way to programmatically manage user lifecycles or enforce granular access controls based on department or role changes. This creates a significant gap for marketing teams that need to manage access to customer data and campaign tools. When employees leave the company or change departments, their ActiveCampaign access must be manually revoked, creating compliance risks and potential data exposure. The lack of automated deprovisioning means former employees could theoretically retain access to sensitive marketing data and customer information until someone manually removes them from the platform.

No SCIM

Payments / Fintech

ProvisioningNot Supported
Manual Cost$11,754/yr

Adyen offers SCIM 2.0 provisioning, but only through Okta's integration—there's no native SCIM endpoint. This creates a significant vendor lock-in scenario where your provisioning capabilities are entirely dependent on using Okta as your identity provider. Teams using Azure Entra, Google Workspace, or OneLogin are left with manual user management despite Adyen supporting SAML SSO with these platforms. The Okta integration itself requires maintaining a company account (not just a merchant account) and keeping at least one non-SSO admin for troubleshooting, adding operational complexity. For payment platforms handling sensitive financial data, this provisioning gap creates serious compliance risks. Your finance team, payment operations staff, and developers need timely access to process transactions and manage risk controls, but without automated provisioning, you're stuck with manual onboarding that can delay critical payment operations. The requirement to maintain non-SSO admin accounts also creates a security backdoor that compliance auditors will flag.
