Multi-modal tracking from origin pickup to door delivery, with proactive exception alerts and shareable read-only links. You see where it is, why it's late, and what we're doing about it — without opening a ticket.
The map below is an illustrative view of one customer's active fleet. Vessel and flight positions update every 15 minutes from AIS, ADS-B and carrier APIs; container-level milestones update within 2 minutes of the carrier event.
Sample — 42 active shipments
Every dot is one shipment, colored by mode (ocean, air, truck). Click through and you get the full milestone timeline, documents, and the named ops person on that record. The red dot on the Red Sea track in this sample is flagging a one-day schedule slip against the contracted ETA — the alert has already fired to the shipper's buyer by the time you see it on the map.
Shareable read-only links expire on a per-link basis (7 days default, configurable) and carry a watermark with the viewer's name when they log in. Useful for end customers, retail compliance teams, or your finance department — without giving them a seat in the portal.
Most tracking tools fire an alert for every event and call it "visibility". We fire on the five exception types that change your plan, and we tell you what we're doing before the alert hits your inbox.
Berth wait, yard dwell or chassis shortage at the destination port. We reroute the container to a nearby terminal or pre-position chassis from our pool the day the signal turns. Alert includes the expected added days and the revised LFD.
CBP exam, FDA hold, or OGA review. Our brokerage desk receives the hold notice directly and starts the response before you see the alert. The alert names the hold type, the exam location, and the expected turnaround.
Typhoon in the South China Sea, ice at the Halifax approach, atmospheric rivers on the LA coast. Alert includes the revised vessel ETA, the affected downstream container moves, and options (roll vs wait) where they exist.
Driver no-show, appointment declined, or LFD-driven re-dispatch. We re-book within 4 hours through our drayage pool and surface the new pickup time in the alert, not a followup email.
BL not surrendered, CI missing a line, packing list inconsistent with invoice. The alert identifies the specific document and the specific field, and routes a signature or upload request to the responsible party.
Tracking only works if the data is plumbed correctly. Here's the full map of signals we ingest and how they reach the shipment record.
Direct integrations with Maersk, MSC, CMA CGM, Hapag-Lloyd, ONE on ocean; Lufthansa Cargo, Cargolux, EVA and integrators on air. Container and AWB events arrive within minutes of the carrier publishing them.
Vessel AIS and aircraft ADS-B feeds supplement carrier events with live positioning — so the map stays accurate even when a carrier's event queue is backed up.
Truck GPS and ELD events from our trucking network. First-mile pickup, arrival at port, drayage leg and final-mile delivery — each a timestamped event on the shipment.
Track at the container, the AWB, the BOL, or the line-item. One PO split across two containers shows up as two linked shipments; one container carrying three BLs shows up as three. No lost lineage.
Email, Slack, Microsoft Teams and webhooks, each with per-channel filters and quiet hours. Your ops team can silence routine events while your buyer still gets every exception.
Read-only tracking links for external parties — end customers, retailer compliance, your finance AR team — with expiry, watermark and scope controls. No new portal seats required.
Rolling-12-month ETA accuracy across the zentralk network, reported as the share of shipments arriving within a stated band of the most recent published ETA. Numbers below are an illustrative snapshot — your account's own accuracy is visible in the portal.
| Ocean FCL · door-to-door |
Within 48 hours of latest ETA: ~82%. Within 5 days: ~96%. Most variance lives in the drayage leg (LFD, chassis) and destination customs hold, not the sailing itself. Sample Rolling 12-month figure for the zentralk network on contracted alliance lanes. |
|---|---|
| Ocean LCL · CFS-to-door |
Within 48 hours: ~68%. Within 5 days: ~91%. Consol receipt and deconsol at destination add variance; ETA discipline is why our LCL desk reserves on flown master bills, not co-load spot. Sample Illustrative — individual account accuracy shown in the portal. |
| Air express · door-to-door |
Within 12 hours: ~88%. Within 24 hours: ~97%. Main variance is gateway customs exam, not the flight itself. Sample |
| Air standard · door-to-door |
Within 24 hours: ~78%. Within 48 hours: ~93%. Consolidation cut-offs and deconsol at destination add a day of variance on roughly one flight in four. Sample |
| Trucking · FTL |
Within 4 hours of appointment: ~91% on lanes under 1,000 miles; ~78% on team-driver expedited lanes over 1,000 miles. Sample |
| Cross-border · US ↔ MX ↔ CA |
Within 12 hours of appointment: ~74%. Border clearance variance (broker queues, ACE/ACI edge cases) is the biggest driver. Alert fires within the hour a clearance delay is identified. Sample |
Sample Figures above are rolling-12-month network averages for illustration only. Your own account's ETA-accuracy by mode is reported in the platform under Reports · Network Performance.
A tracking event without the PO, the document and the invoice attached is half the picture. The other three modules tie it together.
POs, line items and change orders — handed off to freight, one record.
Documents & InvoicesOne folder per shipment.BOLs, CIs and customs filings attached to the same record.
API & IntegrationsPipe it to your stack.Webhooks on every tracking event, HMAC-signed, idempotent.
