Overview
ZoomedXL Courier helps independent contractors find on-demand delivery work—sedans to cargo vans—with route offers, GPS check-in/out, manifest uploads, and same-day payment workflows.
Business problem
Gig couriers need reliable access to local routes, clear job details, and fast payouts without rigid schedules.
Solution
A dual-platform courier app that surfaces route assignments in real time, supports flexible scheduling, and streamlines proof-of-delivery and location workflows.
