Fleet management software tracks trucks. It doesn't route them.

Most fleet management software is built around a GPS feed: where is each truck right now, how fast is it going, has it idled too long. That's genuinely useful for maintenance schedules, fuel reporting, and knowing which driver to call when a customer complains. It answers "where is my fleet," which is a different question from "where should my fleet go."

The gap shows up the moment order volume grows past what a planner can eyeball. A GPS dashboard will happily show you three trucks driving past each other on overlapping routes, because tracking software has no opinion about which truck should have taken which stop in the first place. That decision, capacity-aware, time-window-aware route assignment, sits upstream of tracking, and most fleet management platforms simply don't attempt it.

The two problems are complementary, not competing: routing decides the plan before drivers leave the depot, tracking confirms what actually happened once they're on the road. A fleet running good route optimization and no live tracking is flying blind on execution. A fleet running excellent GPS tracking and no route optimization is meticulously documenting an inefficient day.
