It knows the paperwork a New Zealand van runs on
COF, EWOF, gas certificate, RUC and self-containment are tracked for every van, each against the thing it actually turns on: an expiry date, or the odometer reading. You set how many days ahead each warning starts. The dashboard lists every van with something coming up, overdue first, so a certificate gets booked in a quiet week rather than on the morning a customer is waiting, and a booking warns you when the hire could run past the RUC you have paid.
