CLARITY & COMMERCIAL TERMS

Frequently asked questions

How does the mobile app handle multi-day cross-country trips with no cellular reception?

Every manifest, route map, and delivery instruction is pre-cached to an encrypted local SQLite database before the driver departs. Status updates and signatures commit locally and queue in a persistent journal that syncs automatically when signal is restored.

Can drivers use personal low-cost Android phones or do they need dedicated rugged hardware?

Our React Native architecture is optimized for low-memory devices (sub-2GB RAM) and runs smoothly across both inexpensive Android smartphones and specialized rugged vehicle-mounted tablets.

How do you prevent data conflicts if a dispatcher reassigns a load while a driver is offline?

We use deterministic vector-clock reconciliation rules on the server. If a conflict occurs, the system preserves both states and flags the event in the dispatcher console with full timestamps.

How quickly are billing invoices triggered after delivery confirmation?

As demonstrated in our TransApex Logistics implementation, digital PoD synchronization reduced average billing turnaround from 6.2 business days down to 1.3 business days.
