Build vs Buy: Enterprise SSO for Manufacturing and Supply Chain SaaS Platforms

Enterprise SSO built in house typically requires an estimated $150,000 to $300,000, 8 to 16 weeks of work by two to three engineers, and $75,000 to $120,000 in annual maintenance, with three-year costs potentially reaching $1.3 million to $2.07 million when support and delayed product work are included. The decision is especially significant for manufacturing software because it often serves many small, differently configured tenants, may require on-premises or air-gapped deployments, and must support evidence requirements under CMMC and NIST SP 800-171 for account identification, multifactor authentication, and access-control logging. While implementing SAML, OIDC, and SCIM is technically feasible, ongoing responsibilities include certificate rotation, provider-specific compatibility issues, security updates, provisioning reconciliation, audit exports, and customer support. Building is presented as most appropriate when identity is a core product differentiator, when hard air-gap requirements rule out hosted services, or when contracts prohibit third-party identity processing; self-hosted platforms such as Keycloak may fit these cases but shift costs to operations. For organizations that buy identity services, the key considerations are connection-based pricing, deployment location, auditable event records, compatibility with customers’ identity providers, and the cost of migrating existing integrations.
