Rang Bangladesh Omnichannel Topology :: 25+ Physical Outlets & eCommerce Live Sync

/ ARCHITECTURAL OVERVIEW

The Challenge: Eliminating Stock Desynchronization Across 25+ Outlets

As one of Bangladesh’s leading cultural fashion retail brands, Rang Bangladesh operates over 25 retail outlets across Dhaka, Chittagong, Sylhet, and other major divisions, alongside a high-traffic online store. During peak festival shopping seasons (Eid-ul-Fitr, Durga Puja, Pohela Boishakh), thousands of shoppers purchase items simultaneously in physical stores and online. Previous systems suffered from stock drift, overselling, and slow billing queues.

Core Architectural Capabilities

Offline-First POS Resilience

If branch internet fails, POS registers seamlessly buffer sales in local SQLite and automatically flush transactions upon reconnect.

Live eCommerce Stock Locking

Central PostgreSQL cluster with atomic locks prevents web shoppers from purchasing the last garment if being rung up in an outlet.

Multi-Branch Stock Requisitions

Stores can instantly check nearby outlet inventory and arrange customer transfers with digital gate-pass tracking.

Automated Accounting & Tax Ledger

Every retail and web invoice automatically feeds into general ledger, VAT-11/11Ga compliance registers, and net margin reports.

Long-Term Guardian Custody Guaranteed

CareITLab does not deliver static files and abandon your organization. Every platform we build is backed by direct code-level guardianship, proactive security patching, and ongoing performance tuning under our strict SLA frameworks.
