Case Study: Replacing Phone Call Orders with a Custom B2B Distributor Portal
How Prajin Dezaa engineered a production-grade digital platform for JKI Orders, delivering immediate operational efficiency and international customer inquiries.
The Challenge & Business Problem
Wholesale distributors placed orders through manual phone calls and disorganized WhatsApp messages. This led to frequent dispatch tracking errors, delays in sending GST invoices, and difficult reconciliation of customer payment ledgers.
The Engineering Solution

Core Features Delivered
- Simplified customer authentication using mobile number and secure 4-digit PIN
- 1-tap repeat order functionality based on past buying history
- Real-time warehouse dispatch status tracking and transport LR number logging
- Automated GST invoice generation and printable statement ledgers
- Installable PWA and standalone Android APK for field operators
