Namely SCIM guide

BambooHR does not support inbound SCIM provisioning on any plan. While BambooHR integrates with identity providers like Okta and Entra ID, it functions as the HR source of truth that provisions users TO other systems, not the other way around. This means your IdP cannot automatically create, update, or deactivate user accounts in BambooHR based on HR events or group membership changes. BambooHR offers SAML 2.0 SSO with JIT provisioning, but this only handles authentication for users who already exist in the system. This creates a significant operational gap for IT teams managing employee lifecycle automation. While BambooHR can push employee data to your IdP when HR makes changes, there's no way to automate the reverse flow - provisioning new users into BambooHR itself still requires manual account creation or CSV imports. For organizations where BambooHR isn't the primary HR system of record, this means maintaining dual data entry processes and accepting the compliance risks that come with manual provisioning workflows.

Personio, the HR information system for 10-5,000 employee companies, does not offer SCIM provisioning capabilities. Instead, Personio functions as an HR source system that syncs employee data one-way to identity providers like Okta and Microsoft Entra ID through custom API integrations. While these integrations automate employee onboarding and offboarding by pushing HR data to your IdP every 30 minutes, they don't provide the bidirectional SCIM provisioning that IT teams need to manage user access within Personio itself. Additionally, Personio only supports native SSO via OIDC (not SAML), requiring third-party bridges like JumpCloud for SAML-based SSO workflows. This creates a fundamental gap for IT teams managing Personio access. While your IdP can receive employee data from Personio, you still need manual processes to provision user accounts, assign roles, and manage permissions within Personio when employees join, change roles, or leave. For multi-entity organizations or companies requiring granular access controls, this manual overhead becomes particularly problematic, especially given Personio's Enterprise-tier pricing that averages ~$47,000 annually.

8x8 supports SCIM 2.0 for automated user provisioning, but only on their quote-based X Series plans (previously $24-44/user/month range before they moved to custom pricing). While SCIM can create, update, and deactivate users, it has critical gaps that create ongoing manual overhead: license assignment must be done manually after every user is provisioned, users can't be deleted (only deactivated), and provisioned users don't automatically appear in the Company Directory. For IT teams managing a unified communications platform that typically covers all employees, these limitations defeat much of SCIM's purpose. You're still manually touching every user account to assign licenses and ensure directory visibility. The lack of user deletion support also creates compliance headaches when employees leave - accounts accumulate as "deactivated" rather than being properly removed.
