LogisticsReal-Time GPSEnterprise Platform

Hardware-Free
Fleet Tracking Platform

A complete fleet tracking and dispatch platform for operators managing large fleets — live logistics activity, route-matched assignments and proof of delivery, running entirely on the iPhone and Android devices drivers already carry. No Garmin units, no telematics boxes, no per-device licensing.

The Challenge

Tracking that cost more than it saved.

Fleet operators were tied to dedicated tracker hardware — purchase, licensing, installation and maintenance on every truck, plus a separate app for drivers to manage their actual work. Two systems, two costs, and a hardware dependency that broke the moment a unit failed in the field.

The Solution

The phone in the cab is the tracker.

Custom native background-fetch services keep a one-to-one live link between driver and platform from the moment an assignment is accepted — surviving app kills. The same app handles jobs, ETAs and proof of delivery, so tracking and work happen in one place, with zero extra hardware.

How it works

order to proof of delivery.

01

Order created

A vendor or administrator raises a purchase order and rolls it out to the network.

02

Route-matched

Fleet managers assign directly, or a proprietary matching algorithm offers the job to drivers along the route to accept.

03

Live tracked

Breadcrumbs, heading, ETA, speed-limit crossings and fatigue prediction stream in real time for the whole trip.

04

Proof captured

The driver closes the job with a photo or an electronic receiver signature — configurable per purchase order.

Inside the product

every truck, every second.

Keep tracking alive

Vantra tracks your device only while an assignment is in progress — never on your own time.

Location while on a job
Starts when you accept, stops when you deliver.
Restart after app close
If the app is killed mid-job, the handoff service brings tracking back.
Route trimmed after delivery
Only the clean delivery path is kept on record.

two hard problems.

Real-time data that spikes without warning.

Live telemetry is expensive, and fleet load swings hard by hour and season. Rather than sizing servers for the peak, we moved the utility layer to fully serverless functions that scale at the per-invocation level — no upgrade or downgrade cycle, and cost that tracks actual movement.

Tracking that survives the app being killed.

Background fetch had to be reliable and self-reviving. Every driver signs a consent document, and a native handoff service reinstates tracking after each app kill whenever an assignment is in progress. Built natively via exit strategies, then bridged into React Native.

Track the driver, not the assignment.

Instead of opening a tracking stream per job, the platform tracks the driver continuously and, on completion, distils a clean breadcrumb path as that assignment's delivery record — then compacts the raw route. One stream, accurate history, and storage costs kept near flat as the fleet grows.

Outcomes

less hardware, more control.

$0.75

operational cost per truck per month, down from roughly $110 on tracker hardware and licensing.

End-to-end

control of the delivery lifecycle with zero third-party hardware in the loop.

Real-time

fleet management with breadcrumb optimisation that cuts storage cost and sharpens reporting.
