Rangdhanu POS is a multi-tenant SaaS platform that lets retail businesses run their whole operation from one system. Each shop gets its own isolated database, branding and settings. The platform owner manages shops, subscriptions, billing and permissions from a central admin panel.
The cashier gets a fast billing screen with barcode scanning, hold sale, quotations, refunds and printable receipts. The owner gets live dashboards, stock and expiry alerts, profit and loss, a balance sheet, and a per-salesman performance view. Because the system includes proper double-entry accounting (chart of accounts, journal entries, general ledger, trial balance), the numbers in the reports are accounting-grade rather than estimates.
The product ships as a web app, a desktop app and an Android app from a single codebase. Changes made on one device are pushed to the others in real time.
What Problems Does It Solve?
Problem retail shops face | How Rangdhanu POS solves it |
|---|---|
Slow billing and long queues | Barcode scanning, quick product search, keyboard shortcuts, hold-and-resume sales |
Stock mismatches and "out of stock" surprises | Real-time inventory, low-stock alerts, stock adjustment and full stock history |
Expired or dead stock losses | Product expiry tracking and expiry alerts |
Hard to manage several branches | Branch and warehouse management, stock transfer, branch stock requests, stock by location |
Customer dues tracked on paper | Customer ledger, due balance, due payments, outstanding reports |
No idea of real profit | Profit & Loss, balance sheet, trial balance, expense tracking |
Staff mistakes and theft | Role-based permissions (7 roles), activity log, attendance, salesman performance |
Customers don't come back | Loyalty points, gift cards, membership, SMS notifications |
Manual, error-prone reports | One-click reports with Excel and PDF export (Bangla supported) |
Software stops when internet is slow | Desktop and Android shells, plus a real-time sync design |
Data loss and shop onboarding | Database backup, restore and move tools, plus automated shop provisioning |
Agencies and vendors need to sell it as a service | Built-in subscriptions, billing, free-month grants and per-shop management |
