What is a fleet's most important tax KPI?

The share of fill-ups with a valid CFDI. The healthy band is above 98%; fleets with manual processes hover between 80% and 90% without knowing it.

What counts as an anomalous fill-up?

A fill-up exceeding tank capacity, two fill-ups within two hours, off-hours fueling, or fueling outside the operating zone.
