Onboarding estates accumulate. A flow built for one product gets reused for a second it does not fit. A control added after an audit stays forever because nobody knows what removing it would cost. The result works, roughly, and nobody can say why it works the way it does.
What an unmapped estate like this costs you today is operational time, the manual step nobody signed up to own, and regulatory exposure, the fines that follow when the shadow flow finally surfaces in an audit. Engineering time is the smaller cost, a side effect once the flow is actually mapped. We sell the work to find out what is happening, and a plan that gets you ready, executable with or without us.
