For Commercial Managers
Know what every voyage costs.
Before it starts.
Port disbursements are 8–15% of total voyage costs and the least predictable variable. HarborLab gives commercial teams real-time DA visibility and pre-voyage cost estimates — before the P&L closes.
Port Cost Estimator
Know port costs before the fixture is signed.
Accurate port call cost estimates across 1,000+ ports. Feed them into your voyage P&L before the voyage starts. No more surprises when the final DA arrives weeks later.
DA Validation - Charterer DAs
When DAs are your liability, every overcharge hits your P&L.
HarborLab validates every line item on charterer DAs — against live port tariffs and contracted rates. Overcharges flagged before payment. Dispute emails drafted automatically. Your team approves, not re-does the work.
Questions we hear
We've used our provider for years and they do a good job.
That may well be true. HarborLab doesn't replace your agents. It shows you, line by line, how each DA compares with the tariff and with real port calls in that port, so you can see where the numbers stand.
Switching would disrupt our voyage cycle.
Nothing switches overnight. You keep your agents and your current workflow, and DAs keep arriving the way they do today. HarborLab adds the checks and the market data on top, with onboarding support from our team.
Port costs are a small part of our voyage cost.
They're 8–15% of total voyage costs, and the least predictable part. Small enough to ignore, large enough to hurt.
How do I know your AI is more accurate than human review?
Every flag comes with its reasoning: the quoted amount, the expected amount, the benchmark range and the comparable port calls behind it. Your team sees why, decides and approves. Nothing is approved without them.
We already have real-time visibility in our TMS.
Your TMS shows what was submitted. HarborLab shows whether what was submitted was correct.
This sounds like outsourcing.
With outsourcing, you hand over the work and get a result. With HarborLab, you see every action in real time, choose the agents and can step in on any case. You own the process; we operate it.
