Port Cost Estimator
Know what every port call costs before the voyage.
Know what a port call will cost before you fix. Enter the vessel, port, activity, and cargo, and get a full cost breakdown by charge type, in USD, in minutes. Estimates come from HarborLab’s own tariff algorithms, based on the vessel’s dimensions and live tariff data from agents worldwide, not a rough quote.
Features: Basic and Advanced modes · Breakdown by charge category · Benchmarked against 40,000+ real port calls
· Feeds your voyage P&L before the fixture is signed
Husbandry Estimator
Start knowing what husbandry should cost.

Budget crew changes, spares, launches, and attendances with confidence. Every husbandry service is defined the same way across every agent, so you compare like with like, and it predicts cost per service and per vessel type in +1,400 ports.

Features:
· Crew changes, spares and supplies, superintendent visits, inspections, surveys, cash to master
· Per-service prediction
· Basic and Advanced modes
DA Management
Every charge verified. Before you pay it.
HarborLab AI checks every line of every PDA and FDA against the tariff, comparable port calls and your agreed rates. It corrects wrong parameters, flags anything out of line with the reason, and drafts one query to the agent covering every overpriced port and husbandry item. Your team reviews the exceptions and approves.

Features: 

· DA Assistant

· Tariff and market checks

· AI Negotiator

· 17 cost-saving categories

· Invoice validation

· Bulk approval

· Full voyage context on one screen

· AI document scanning

Claims
Claims ready when the vessel sails.

Start your laytime and demurrage claim with a Statement of Facts nobody can dispute. Master and agent capture events in one live, digital record and sign it electronically, so the timeline is complete and consistent before the vessel leaves port.

Features:

· Digital Statement of Facts

· Master and agent sign-off

· Required events checked before signature

· Full audit trail

· Laytime and demurrage calculation

Payments
Pay approved DAs without leaving the platform.
Settle approved DAs directly from HarborLab through our Ebury integration. The exchange rate is shown upfront, and the agent’s bank details are checked against the invoice before any payment goes out.

Features:

· Direct settlement

· Ebury integration

· Transparent FX
