Enterprise readiness, B2B SaaS CIAM, and Self-Serve SSO/SCIM are the same problem

Moving upmarket is usually described as a go-to-market decision.

Paycux engineering

Moving upmarket is usually described as a go-to-market decision. It arrives as an engineering one: a list of requirements attached to a contract, with a date.

This piece walks through how we think about it at Paycux, what we have changed our minds about, and where the sharp edges are.

How the providers actually compare on inbound SCIM

How the providers actually compare on inbound SCIM deserves its own treatment. Price the work honestly. A quarter spent building identity plumbing is a quarter not spent on the product the customer actually chose you for, and that trade should be made deliberately rather than by default.

The cost is not the first integration; it is the long tail. Providers disagree in small ways, certificates expire, tenants move, and each one becomes something you own indefinitely.

Why this matters more than it sounds

Why this matters more than it sounds deserves its own treatment. The cost is not the first integration; it is the long tail. Providers disagree in small ways, certificates expire, tenants move, and each one becomes something you own indefinitely.

The requirements look arbitrary until you map each one to a failure the buyer has already lived through. Single sign-on exists because someone left and kept access. Provisioning exists because a contractor's account outlived their contract.

  • Map each requirement to the failure it prevents
  • Count the long tail, not the first integration
  • Decide who owns the plumbing for the next three years
  • Make the buy-versus-build trade explicitly

See how Paycux lines up against your own path

See how Paycux lines up against your own path is where this gets concrete. The cost is not the first integration; it is the long tail. Providers disagree in small ways, certificates expire, tenants move, and each one becomes something you own indefinitely.

Where this leaves us

If there is one thing worth taking away, it is that the expensive decisions are the ones made implicitly. Making them on purpose costs an afternoon.

If you are working through the same problem and want to compare notes, the docs cover the mechanics and the console shows the behaviour on your own data.

Everything here, already built

Sign-in, enterprise SSO, directory provisioning, roles and an audit trail behind one API. Start with the quickstart and have a working sign-in this afternoon.
