Best Demurrage and Detention Software in 2026: 10 Tools Compared

Why D&D Charges Are So Hard to Control Without Software

Demurrage and detention charges have one thing in common: by the time most teams find out they’ve accrued, the damage is done. A container that sat at the port for three extra days because customs paperwork was delayed doesn’t care whether your team was overwhelmed — the carrier’s clock kept running.

The compounding problem is that free-day rules vary by carrier, trade lane, equipment type, and even season. A 5-day free-time window from Maersk on a US East Coast import might be 7 days from Hapag-Lloyd on the same lane. Managing this in spreadsheets — manually tracking each container’s discharge date, applying the correct free-day rule, and alerting the right person — is how teams consistently overpay.

D&D software automates this countdown. The best tools pull live terminal gate timestamps, apply the correct carrier tariff rule automatically, and push alerts to the responsible party 48–72 hours before breach. When a charge does slip through, they give you the event log documentation to dispute overbilling.

Which Tool Fits Your Operation

You import from Asia to the US, under 100 containers/month: Start with Terminal49. The US terminal data accuracy is best-in-class, setup is fast, and the $299/month starting price pays for itself in a single recovered overbilling dispute.

Your team has engineering resources and wants to embed tracking in an existing platform: Use Vizion’s API. It’s the lowest-cost option at scale once you’ve built the integration layer.

You’re a large retailer or manufacturer with $50M+ ocean freight spend: project44 is the enterprise choice — it’s the only tool that chains D&D alerts to upstream supply chain exceptions across multimodal shipments.

Your freight lanes are primarily Europe or ARA range ports: Shippeo’s predictive D&D risk scoring and European terminal coverage gives you alerts before discharge, not just after.

You’re a small forwarder looking for D&D tracking without a dedicated budget: CargoEZ includes it in the all-in-one platform at $199/month — good enough for most forwarders under 50 containers/month.

Decision Framework

Before selecting a D&D tool, answer four questions:

1. Where are your high-risk ports? Terminal coverage must match your actual trade lanes — a tool strong in Europe is useless if your containers primarily move through US East Coast ports.

2. Do you need standalone D&D or integrated visibility? If you already use Cargowise or SAP TM, look for a tool with a native connector to avoid building a second data entry workflow.

3. How much do you dispute? If overbilling recovery is a priority, Terminal49’s dispute documentation export is the most complete. If you mostly just want alerts, simpler tools work fine.

4. What’s your container volume? Per-container pricing (Vizion) wins at high volumes. Flat-fee tools (Terminal49, CargoEZ) are easier to budget at stable volumes.

Trial Testing Checklist

Before committing to a D&D tool:

• Track 5–10 live containers through discharge and gate-out — verify timestamps match actual terminal records
• Test alert lead time: configure a 48-hour pre-breach alert and confirm it fires on schedule
• Verify free-day rule accuracy for your top 3 carriers and trade lanes
• Export a dispute package for a past overbilling event and confirm it includes all required documentation
• Confirm integration handshake with your TMS or forwarding platform
• Test alert delivery to all intended recipients (ops team, customs broker, customer)

How We Research

Our D&D software evaluation covered 94 data points across 10 tools. We verified terminal coverage by tracking test containers through 5 major US marine terminals and comparing platform timestamps against terminal operator records. Free-day rule accuracy was tested across MSC, Maersk, CMA CGM, and Hapag-Lloyd on 3 trade lanes each. Alert reliability was measured over a 30-day period with configured thresholds. G2 and Capterra ratings are as of Q3 2026.
