Enterprise SSO has always come with a tax — on your team's time, on your per-connection bill, or both. FusionAuth 1.65.0 cuts the SSO tax.
Here's a pattern I've seen repeated across B2B SaaS companies at every stage.
You close your first enterprise deal. It's proof you've built something enterprises actually want. Six weeks later, their IT admin emails your dev ops team about SSO. Your engineering team handles it. By "handles it," I mean a ticket, a back-and-forth, an admin session, and a misconfiguration that doesn't surface until someone tries to log in for the first time.
Three weeks. One customer.
Now you've got four more enterprise deals in the pipeline, and every one of them will follow the same story.
The math breaks faster than you think#
Close the deal. Get the SSO request. Handle the configuration. Find the misconfiguration in production. Fix it.
One customer: manageable.
Five customers: a cost your engineering manager is quietly absorbing.
Twenty customers: a line item your CFO is going to notice and your CTO is going to have to answer for.
This isn't a technical problem. Your product works. Your auth stack works. The problem is that the wrong team owns the process. Your engineers are doing IT work for your customers' companies because those customers have no self-service path. Every enterprise deal you close makes the problem worse.
That's the case your CTO needs to hear. Not 'this is annoying' - but 'this is a scaling problem and FusionAuth 1.65.0 fixes it'.
There's also a pricing problem — depending on how you're solving it#
If you've been evaluating other platforms to solve this, you've likely seen two pricing models in the market — and both have the same problem.
Some charge per SSO connection. $125 per connection per month to start. Twenty enterprise customers: $2,375 per month with price scaling, just for the self-service SSO layer, before you've written a line of product code. That number grows with every deal you close.
Others cap enterprise connections at the plan level rather than charging per connection. Three connections on one tier, five on the next. Your sixth enterprise customer forces a jump to their top tier and a sales conversation. If you started on a lower-cost track and added enterprise buyers, you've already hit their pricing trap — minimum pricing jumps of 4x or more, for the same MAU cap.
The mechanism differs. The outcome is the same: unpredictable costs that multiply as you scale.
Most teams accept this as a cost of doing enterprise business. You shouldn't, because it isn't.
What's Coming In FusionAuth 1.65.0#
Tenant Manager now includes a complete self-service SSO configuration flow.
Your enterprise customer's IT admin logs in, selects and configures their identity provider, and tests their configuration. Once it works, they enable it themselves. No ticket. No back-and-forth with your team.
Customers can configure this flow with either SAML v2 or OIDC. For OIDC, the discovery endpoint auto-populates configuration from the issuer URL. Most modern providers — Okta, Entra, Google Workspace — resolve with a single field.
You keep control of the guardrails. You set which IdP types each tenant can access and define the linking strategies. Your customers work within those guardrails without engineering tickets and calls.
The test is what actually matters#
The most common SSO escalations I've seen have been caused by misconfigurations. Settings that looked correct but failed when someone tried to log in.
Self-service SSO in FusionAuth 1.65.0 makes IdP configuration easy to test against a real identity provider before you deploy to production. If the configuration doesn't work, FusionAuth shows an error log that helps your customer debug their configuration without contacting your engineers.
Your team never even knows it happens because your customer handled it themselves.
Your CTO cares about outcomes: customers get to production faster and your engineers stop absorbing the cost of someone else's IT work.
Pricing and architecture: two advantages that don't change#
Self-service SSO in Tenant Manager cuts both the operational and pricing taxes. FusionAuth has two platform advantages that make it the stronger choice at enterprise scale: pricing that stays flat as you grow, and an architecture your competitors can't offer.
FusionAuth platform licensing covers all SSO connections. No per-connection charge. No plan-tier forcing. The cost stays flat as your enterprise customer base grows. For 20 enterprise customers, that's $2,375 per month you're not paying.
And FusionAuth is the only commercial CIAM platform in this category with a single-tenant deployment option in any cloud region of your choice – including self-hosted. Every major alternative is multi-tenant cloud-only. If you're selling into financial services, healthcare, or government, or into EU markets where data sovereignty is a contractual requirement, isolated single-tenancy is a requirement only FusionAuth can meet. Those deals are yours to close.
What to do now#
As you're evaluating FusionAuth, ask to see Tenant Manager SSO in your demo. The full flow - configuration, test, enable - runs in under 15 minutes against a real IdP. That's what you bring back to your CTO.
Already on FusionAuth? In the Admin UI, navigate to Tenants, open your tenant configuration, and find the SSO settings. Point your enterprise customers at Tenant Manager from there.
