Overview
The project
in context.
Fill'er removes the need to visit traditional gas stations by bringing fuel trucks directly to office parks, job sites, and fleet yards. StartxLabs built the mobile refueling application, automated price locking at time of order, and route optimization for fuel delivery drivers.

The challenge
What was
blocking progress.
Commercial fleets lose valuable operational hours sending drivers to gas stations during work shifts.
01
Vehicle pin location required exact parking spot tagging with license plate identification
02
Fuel delivery trucks needed hazardous material route compliance and dispatch queuing
03
Real-time fuel price lock at time of order reservation
04
Commercial fleet managers needed multi-vehicle scheduled refueling orders
Our solution
