Monitor Japan Post (EMS / Yu-Pack) delivery performance, SLA risk and cost per order, and catch carrier problems before customers feel them.

No changes are made without the configured approval policy. Read-only operations do not modify the connected system; schedules, access scopes, API usage and data handling remain governed by Vortex IQ controls.
