Shohnaat Logistics — Enterprise Multi-Tenant Courier SaaS

Shohnaat Logistics is an enterprise-grade, multi-tenant parcel courier and freight management SaaS platform engineered for 10-year architectural longevity and zero-loss financial integrity. Built with a unified Next.js web application and a modular Node.js/Express service layer, the platform orchestrates multi-branch sorting hubs, automated merchant fulfillment, and mobile field rider dispatch workflows. To guarantee absolute financial auditability across nationwide delivery operations, Shohnaat implements a bank-grade double-entry accounting ledger where every Cash-On-Delivery (COD) collection, hub transfer, rider commission, and merchant payout requires mathematically balanced debit and credit entries. High-throughput parcel status transitions, automated tracking webhooks, and event notifications are processed asynchronously using dedicated Redis 7 and BullMQ worker queues, while the entire production ecosystem is containerized and coordinated via Docker Compose on PostgreSQL 16+.
