Seazone — International Freight & Shipping Management Platform

Seazone is a full-stack SaaS platform built for international freight forwarding and shipment logistics. It provides an end-to-end solution for managing sea shipments — from booking and customs clearance to real-time tracking and financial settlement.

What it does

- Shipment Management — customers can create, group, and track shipments through the full lifecycle, from origin to destination.

- Customs & Tax Engine — automated customs duty and tax calculations using HS codes, supporting multiple unit types (weight, count, percentage), with per-item consumer spending fees and financial tax breakdowns.

- Multi-Currency & Multi-Language — full i18n support with dynamic translations and live currency management, making the platform usable across international markets.

- Notification System — real-time push notifications (Firebase FCM) and email alerts for shipment status changes, tracking updates, and customs events.

- Admin Dashboard — a management interface for admins to handle users, countries, currencies, page content, financial taxes, support tickets, and audit logs.

- Customer Mobile App — a companion app (iOS & Android) with push notifications, shipment tracking, and account management.
