Orders & Bookings

Create POs and book freight from one place.

Whether we source the goods or you do, every PO lives in the portal. Convert it to a freight booking in a click — ocean, air or truck — with quotes attached. Line-item splits, change orders and multi-supplier POs are all first-class concepts, not spreadsheet workarounds.

  • Create POs against a supplier or upload from your ERP
  • Request and compare freight quotes by mode and lane
  • Book the winning quote and watch it become a live shipment
  • Role-based approvals so your head of sourcing sees the PO first

Live Tracking

See every milestone the moment it happens.

Vessel positions, flight legs, container milestones, customs status, drayage and final delivery — pushed in real time with exception alerts to the right person. We fire on the five exception types that actually change your plan, not on every event.

  • Live vessel and flight ETAs from carrier APIs, AIS and ADS-B
  • Milestone timeline (Booked → Loaded → Sailing → Cleared → Delivered)
  • Exception alerts via email, Slack, Teams or webhook
  • Shareable read-only links for buyers and end customers

Documents & Invoices

Every document attached to its shipment.

Bills of lading, commercial invoices, packing lists, COOs, customs entries and freight invoices — auto-attached to the right shipment, version-controlled, and searchable. Retention set to the longest applicable jurisdiction, so your audit trail outlasts any single compliance cycle.

  • Auto-pull docs from carriers, brokers and suppliers
  • One consolidated freight invoice per shipment or per month
  • Export to CSV, Excel or your ERP via API
  • Full audit trail with timestamps, user actions and diff view

API & Integrations

Wire your stack to your shipments.

A REST API, webhooks, EDI, and pre-built connectors for the storefronts, ERPs and accounting tools our clients actually use — Shopify, WooCommerce, Amazon, NetSuite, QuickBooks, Dynamics 365. Where a connector doesn't exist, the webhook fills the gap.

  • REST API with OpenAPI 3.1 spec, versioned with 12-month deprecation
  • Webhooks on every state change, HMAC-signed, 30-day replay
  • EDI gateway for X12 (850/855/856/810/940-945/997) and EDIFACT
  • OAuth 2.0 authorization + API-key server-to-server auth
