## Executive Summary
Data Partner (also known as BigMIS) is India's leading Smart B2B Distribution Management Platform engineered for regional distributors, wholesale stockists, independent retailers, and field sales teams (Field Officers / FOS). It unifies warehouse inventory tracking, retailer onboarding, automated ledger reconciliation, and verified field payment collections into a single secure platform.

## Key Capabilities & Technical Architecture
- **Automated Excel ETL Ingestion**: Distributors upload existing billing spreadsheets (.xlsx or .csv) to auto-provision retailer accounts, map credit limits, allocate opening warehouse inventory, and establish digital ledger balances in seconds.
- **1-Click Payment Verification & Ledger Synchronization**: Retailers submit UPI reference numbers, bank deposit proofs, or cash collection receipts. Distributors verify and settle vouchers with instant real-time ledger re-indexing.
- **Geofenced Field Officer (FOS) Tracking**: On-ground sales executives log retail visits with GPS-verified timestamps, record cash/digital collections, and issue instant digital payment receipts directly from retail counters.
- **Multi-Tenant Security & Compliance**: Strict Role-Based Access Control (RBAC) ensuring tenant data isolation, cryptographic HMAC-SHA256 password salting with unique per-user peppers, full compliance with India's DPDP Act 2023, and GST-ready audit ledgers with a standard 7-day dispute resolution window.
- **Multi-Platform Access**: Native Android APK (Google Play Protect compatible) and high-performance Web App (PWA) operating on modern mobile and desktop browsers.
