Intermodal drayage operations face one of the most complex billing environments in freight transportation. A single container move can generate separate invoices from the ocean carrier (demurrage), the chassis pool provider (per diem), the rail ramp or marine terminal (storage), and the motor carrier's own line-haul or drayage tariff. When these charges are split across multiple parties and governed by different free-time clocks, manual reconciliation becomes error-prone and expensive.
Strong Tower Consulting designs and implements dispute resolution engines that automatically reconcile these overlapping rule sets. The systems ingest real-world gate events, model contract tariffs, and generate dispute packages that recover revenue while reducing administrative overhead.
Core Components of an Effective Dispute Resolution Engine
A production-grade intermodal chassis and demurrage engine contains four tightly integrated modules:
- Event Ingestion Layer - Real-time or batch ingestion of gate transactions from rail ramps, marine terminals, and chassis pool operators. Data arrives via EDI 214, API feeds, or flat-file extracts.
- Tariff Rules Engine - Declarative modeling of each steamship line's Last Free Day (LFD), per diem, and storage rules. Rules are versioned by contract and effective date.
- Reconciliation Engine - Compares actual dwell times against allowed free time, accounting for weekends, holidays, and force-majeure clauses. Flags variances and calculates recoverable amounts.
- Dispute Workflow & Ledger - Generates formatted dispute packages (PDF + EDI 210 or custom API payload), tracks status, and maintains a recovery ledger that feeds directly into driver settlement and accounts receivable systems.
Operational Data Comparison: Manual vs Automated Reconciliation
| Metric | Manual Process | Automated Engine | Typical Improvement |
|---|---|---|---|
| Containers reviewed per month | 800-1,200 | 12,000+ | 10x volume capacity |
| Average time per dispute package | 38 minutes | 11 seconds | 99% reduction |
| Per diem & storage recovery rate | 21% | 67% | +46 percentage points |
| Monthly recovered revenue (5000 moves/mo) | $18,400 | $94,700 | 5.1x increase |
| Administrative FTE required | 2.3 | 0.4 | 83% labor reduction |
Integration with Existing TMS Platforms
Our architectures are deliberately TMS-agnostic. Whether your operation runs McLeod LoadMaster, TMW Systems, Truckmate, or a custom SQL-based dispatch system, the dispute engine reads directly from the operational database. Key integration points include:
- EDI 204 inbound load tenders and 214 status updates
- Driver settlement and escrow accounting tables
- Fuel surcharge and accessorial billing modules
- SQL Server views that correlate order, leg, and equipment movement records
- Real-time API hooks for ELD and telematics dwell timestamps
This deep integration allows the engine to automatically adjust driver pay when per diem or demurrage is successfully disputed and recovered, maintaining accurate settlement ledgers without double-entry.
Port/Rail Ramp Gate Event Verification Workflow
The highest-value disputes require irrefutable proof of gate events. The system automatically correlates:
- Chassis pool interchange (in/out) timestamps
- Rail ramp or terminal gate transaction logs
- Ocean carrier Last Free Day calculations
- GPS-derived dwell time at the facility (when available)
When a mismatch is detected, the engine assembles a dispute package containing the supporting timestamps, rule citations, and calculated overcharge. The package is transmitted via the steamship line's preferred channel (web portal upload, EDI, or API) and tracked until resolution.
Implementation Considerations for Motor Carriers and Drayage Fleets
Successful deployments require careful attention to data quality. Common prerequisites include clean chassis unit numbering, consistent gate event logging, and documented contracts with each ocean carrier and chassis pool. Strong Tower Consulting performs a systems assessment that maps current data flows, identifies gaps, and produces a phased implementation roadmap.
Because Strong Tower Consulting, LLC and Exspeedite LLC are separately organized sister companies under common ownership, carriers receive independent technology architecture advice without pressure to purchase software. Our only product is better decisions.
Frequently Asked Questions
How does an intermodal chassis per diem dispute engine reconcile Last Free Day rules with actual gate events?
The engine ingests ocean carrier tariff rules via EDI or API, models them in a rules engine, then matches them against actual in-gate and out-gate timestamps from the rail ramp or port terminal. Discrepancies are flagged automatically and formatted into dispute packages for the steamship line.
What data sources are required for a terminal storage and demurrage dispute resolution system?
Core sources include: chassis pool interchange records (typically 214 or proprietary API), rail ramp gate transaction logs, ocean carrier Last Free Day and free time rules, and internal load status from the TMS (Truckmate, McLeod, or TMW). Additional value comes from GPS dwell timestamps and driver settlement records.
Can this technology integrate with existing trucking TMS platforms?
Yes. Strong Tower Consulting designs dispute engines that read directly from SQL Server schemas used by McLeod, TMW, and Truckmate. EDI 204, 214, and 210 transactions are parsed and correlated with chassis and demurrage events to automate recovery ledgers and driver settlement adjustments.
What is the typical ROI timeline for an automated intermodal dispute resolution engine?
Most intermodal carriers and drayage fleets see positive ROI within 4-6 months. The largest gains come from recovered per diem and storage charges that were previously written off, plus dramatic reduction in administrative labor required to manually reconcile split billing.
Strong Tower Consulting has been helping motor carriers, freight brokers, and private fleets optimize their technology stack since 2008. Founded in Minnesota by Scott Elliott, the firm brings more than 18 years of independent systems architecture experience to every engagement.
If your intermodal or drayage operation is losing margin to unrecovered per diem, demurrage, or terminal storage charges, an independent assessment is the logical first step.
