Gusto SCIM guide

Paychex Flex, the HR and payroll platform, does not offer native SCIM provisioning on any plan. While Paychex provides SAML 2.0 SSO integration with identity providers, this creates an unusual challenge: as an HR system, Paychex is typically the source of employee data that provisions other applications, not the destination. However, for organizations using Paychex alongside other IdP-managed applications, manual user management becomes necessary. Okta does offer a provisioning connector with Schema Discovery and Attribute Writeback capabilities, but this requires Okta Enterprise and doesn't address integration with other identity providers. This positioning creates a gap for IT teams managing hybrid identity environments. When Paychex serves as your HR system of record but you need to provision users into Paychex from your primary IdP (perhaps for contractor access or cross-system synchronization), you're forced into manual processes or expensive third-party middleware solutions like RoboMQ Hire2Retire. The lack of standardized SCIM support means each IdP integration requires custom configuration and ongoing maintenance.

Paycom, the HR and payroll platform for mid-market companies (50-750 employees), does not offer native SCIM provisioning on any plan. While Paycom supports SAML 2.0 SSO integration with major identity providers, user provisioning requires third-party middleware solutions like RoboMQ Hire2Retire or Aquera Sync Bridge. This creates a complex integration architecture where IT teams must manage and maintain additional middleware components just to automate basic user lifecycle operations. The lack of native SCIM support is particularly problematic given Paycom's role as an HR source system. As employee data changes in Paycom—new hires, role changes, terminations—these updates don't automatically propagate to connected applications without custom middleware. This forces IT teams to either manually sync user accounts across systems or invest in expensive third-party solutions that add complexity and potential failure points to their identity infrastructure.

Paylocity offers native SCIM provisioning that's included with all plans starting at $22-32/employee/month. The implementation is solid for an HR platform—supporting user creation, attribute updates, and deactivation across major identity providers like Okta, Entra, and OneLogin. However, there are operational friction points that complicate deployment: SCIM usernames are restricted to 8-20 characters, users must have both username and work email populated in the HR module before provisioning works, and Okta customers must contact Paylocity support directly to enable SAML 2.0 before SCIM can function. These seemingly minor requirements create real deployment headaches. The username length restriction can break existing naming conventions, the HR module data prerequisite means provisioning fails silently if employee records aren't properly configured, and the Okta support dependency adds weeks to what should be a straightforward integration. For IT teams managing multiple provisioning integrations, these platform-specific quirks multiply administrative overhead.
