The Problem
Managing port costs is broken
Manual processes, invisible overcharges, and zero benchmarking across every port call, every voyage.
No Transparency
Port costs close last. Overcharges go undetected. No real-time view of what a port call actually costs until weeks after the voyage ends.
Avg $700
lost per port call
No Benchmark
You don't know if your agent rates are competitive. Negotiation is based on assumptions, not market data.
50,000+
port calls benchmarked
Manual Overload
200-page tariff documents. Spreadsheets. Email chains. DA checking done manually or not done at all.
60-70%
of DA time is rework
