The problem

Where the time and money actually go.

Free-time rules, terminal events, appointments, holds, invoices, and communications are fragmented; valid disputes expire while teams assemble proof.

Who feels it

Logistics analysts, AP/AR, port and drayage operations

Trigger to act: Detention/demurrage expense is rising, invoice support is weak, port congestion creates exceptions, or a freight-audit provider wants a new recovery product.

Outcome & ROI

The result you can model before you sign.

Illustrative, replace with your data
$14,000
per month, illustrative

Illustrative only: $350,000 annual detention/demurrage spend × 4% additional validated recovery = $14,000 annual recovery. Back-test against closed invoices before setting commercial expectations.

The outcome, plainly: Reconstruct container and appointment timelines, test charges against contracts and evidence, and prepare review-ready disputes.

How it works

Inputs in. A cited, review-ready result out. Your expert decides.

A Document AI + workflow agent. Every material fact is grounded in an allowed source and returned with its identifier, no invented data.

The human gate

AI-Native, not autonomous. Judgment stays with your people.

The machine does the work; the human’s role narrows to the one thing that matters, judgment. That constraint is what makes it safe to deploy.

Non-negotiable human gate

An experienced analyst approves contractual interpretation, dispute amount, and carrier/terminal communication; legal claims route to counsel.

What it will never do
No legal conclusion
No automatic nonpayment
No assumption that every operational delay is disputable
No fabricated appointment or hold evidence
The scorecard

A scorecard, not a demo. We baseline what breaks in production.

Every deployment ships with an evaluation suite. These are the numbers we baseline before launch and monitor after.

This implementation

Fixed-scope, tuned to your systems and rules, grounded in your data, with the human gate and audit trail built in from day one. A price you own, not a subscription you rent.

✓ Fixed price, not a seat subscription ✓ Grounded in your data & rules ✓ Human approval on consequential actions ✓ Auditable decision trace
Systems & integrations

It plugs into the stack you already run.

No rip-and-replace. Access is scoped to the minimum data necessary, isolated per tenant, and fully logged.

Pricing

Transparent by design. The build price buys the workflow and the proof.

A fixed implementation fee plus a monthly bill that scales with volume and governance. No hidden seats.

Why this is safe to try
01Baseline first. We measure your current numbers before we build anything.
02Fixed scope, fixed price. One process in the pilot. No open-ended engagement.
03Expand only if the scorecard earns it. You see the measured result before committing to production.
04Your people stay in control. The human gate means nothing consequential happens without a person’s approval.
FAQ

Questions serious buyers ask.

Does the AI act on its own?

No. An experienced analyst approves contractual interpretation, dispute amount, and carrier/terminal communication; legal claims route to counsel. The system drafts and recommends; a human approves every consequential action. Explicitly excluded: No legal conclusion; no automatic nonpayment; no assumption that every operational delay is disputable; no fabricated appointment or hold evidence.

How do you stop it inventing facts?

Every material claim is grounded in an allowed source record and returned with its source identifier. The system separates observed facts, model inference, and missing information, and routes to a human whenever confidence is low, evidence conflicts, or an adverse outcome is possible.

What does it cost to run each month?

A usage bill of roughly $850–5,500 per month (10,000 to 40,000 document pages per month; OCR/form extraction, model verification, storage and workflow compute), plus a $2,200 per month managed retainer for evaluation, monitoring and maintenance. Your existing platform licenses are separate and already yours. Exact figures are confirmed during scoping.

Do we need a ChatGPT or Claude subscription?

No consumer ChatGPT or Claude subscription is required for the production workflow. The client needs an approved API/cloud billing account. Workspace seats are optional for internal prototyping and administrator access.

How is this different from Veson Nautical?

Tools like Veson Nautical, Cargoes/DP World tools, and Trax are broad platforms you adapt to. This is a fixed-scope implementation tuned to your systems and rules, grounded in your data, with the human gate and audit trail built in, and a transparent price instead of a seat subscription.

How long until it is live, and how do we prove it works?

We baseline the spend-audited rate first, then measure against that baseline. You see the scorecard before expanding scope: the evaluation suite ships with the system, not as an afterthought.
