Choose what changed and when. Sponsoro identifies the relevant reporting workflow, calculates the working-day deadline where possible, and shows what to do next.
Event-aware
Sponsored-worker circumstance changes are generally reportable within 10 working days. Organisation changes are generally subject to a 20-working-day window — but the event itself matters. Sponsoro checks the event before choosing the clock.
