VeloIQ™ Yard & Demurrage Sentinel — Detention Cost Caught Before It's Billed

Every trailer's dwell time tracked from gate-in to gate-out, checked automatically against its carrier's free-time allowance. A yard visit is flagged the moment it crosses 75% of its free time — not discovered when the detention invoice arrives. Dock door assignments, gate events mapped to ANSI X12 EDI 214, and detention charges mapped to EDI 210 — all in one operational view.

A guided tour of Yard & Demurrage Sentinel

Every user journey, the dashboard, and the AI Management Console — walked end to end.

From the gate camera to the carrier's detention invoice — one platform

A single platform for yard operations teams — connecting yards, dock doors, carriers, drivers, trailers, gate events, yard visits, and detention charges across the whole facility.

🚛

Who it’s for

Warehouse Operations Directors, Yard Managers, and Logistics Controllers.

⚙️

Unlimited-user operations layer

Gate security and yard jockeys log arrivals, departures, dock door assignments, and trailer states — unlimited users, no per-seat cost, no ERP/TMS overhaul required.

🧠

AI analytics for the decision-maker

The Logistics Controller queries trailer dwell time, detention risk, and carrier cost exposure in plain English.

Every module a yard operations team needs, pre-built

Purpose-built data models, workflows, and views — generated by the VeloIQ™ framework and refined for the vertical.

Yard & Dock Doors

Distribution-center yards identified by GS1 GLN, with dock doors tracked by type, status, and maximum trailer length.

Carriers & Drivers

Trucking carriers with SCAC codes and default free-time allowances, plus the drivers who check trailers in and out at the gate.

GS1 SSCC Trailers & Gate Events

Trailers identified by 18-digit Serial Shipping Container Code, with every gate crossing mapped to a standard ANSI X12 EDI 214 status code.

Detention Risk Auto-Escalation

Every yard visit is checked automatically against its carrier's free-time allowance — flagged approaching_limit at 75% of free time and detention_accruing once it's exceeded.

Dock Door Assignment

Trailer-to-dock-door assignments for loading, unloading, drop, and hook operations, tracked from assignment to release.

EDI 210 Detention Billing

Detention/demurrage charges computed automatically from accrued minutes and hourly rate, with high-value charges auto-invoiced.

Deployable on day one

VeloIQ™ Yard & Demurrage Sentinel ships as a complete, working application — not a template you still have to build.

📦

Pre-bundled & seeded

Arrives with realistic sample data (2 yards, 12 dock doors, 6 carriers, 10 drivers, 14 trailers, 19 gate events, 14 yard visits) plus a clean production-ready database. Explore instantly, then switch when you go live.

💬

Pre-configured NL analytics

5 pre-configured NL chats with 28 sample sentences — yard operations, detention & carriers, and dock & facility utilization (native), plus detention-risk and gate-throughput AI assistants (agentic).

Runs out of the box

One veloiq run and the full application is live: REST API, React frontend, admin back-office, and AI console — all on your own infrastructure.

Tested & verifiable

Automated smoke, regression, and licensing suites ship with the app, including checks that every yard visit's detention minutes match its dwell time and free-time allowance, and that auto-invoicing actually fired.

Turn yard visibility into a durable margin advantage

Measurable outcomes for every role — from the gate guard to the Logistics Controller.

⏱️

Detention caught before it's billed

Every yard visit is flagged the moment it reaches 75% of its free-time allowance — a call to move the trailer, not a surprise invoice next month.

💰

No more manual detention math

Detention minutes and accrued charge amount are computed automatically from dwell time, free-time allowance, and hourly rate.

🚦

High-value charges bill themselves

Any detention charge reaching $500 auto-invoices the moment it's computed — the back office never has to notice on their own.

🚪

Dock door bottlenecks visible

Every dock door's status and assignment history sits in the same system as the trailers waiting for it.

📋

ROI in one CSV upload

Prospects can upload a month of past detention invoices via the Data Import Engine to see immediately where money was leaked.

🛡️

The yard's digital bodyguard

IQVigilant's Exception Management watches for trailers approaching their free-time limit, with a 1-user free-tier license included.
