Jewellery Shop ERP System

An enterprise-grade platform managing inventory, live gold rates, old gold exchange, and complete jewellery business accounting.

The Story

Jewellery retail runs on numbers that shift by the hour — gold rates, purity, making charges, wastage — and every sale, exchange, and pawn transaction has to reconcile against them instantly. I built a desktop and Android ERP that ties live gold rate feeds directly into billing, valuation, and accounting, so Mahadev Jewellers could stop calculating fine weight by hand.

By linking the store's physical counters to a central ledger, inventory changes are audited in real time. The custom calculation engine seamlessly resolves fine-weight conversion rates, ensuring consistent, error-free accounting throughout high-volume retail seasons.

Chapter 03

A unified ledger serving sales counters, owners, and bookkeepers.

Sales Staff

Billing & Sales Returns

Operates billing screens, records metal weights, handles direct sales returns, and prints clean invoices.

THE PAIN

Recalculating fine metal weights and making charges manually per transaction.

Owner & Management

Dashboard & Valuation

Monitors store valuations, tracks old-gold pawn accounts, checks sales analytics, and sets standard configurations.

THE PAIN

No single unified view of purchases, old-gold exchanges, and girvi liabilities together.

Accounts Team

GST & Multi-payment Reconciliation

Reviews financial ledger reports, files tax returns, and balances daily cash drawer registries.

THE PAIN

Manual ledger entries required across cash, card, and exchange transactions.

How It Was Built

Technical Approach

The ERP system is built on a fast, offline-capable database synchronization layer that connects local desktop counters with an Android dashboard app. Valuation engines calculate multi-karat gold weights, wastage, and making charges atomically on every transaction to prevent ledger drift.

Inventory Management

Item-wise barcode tracking and purity tags (18K, 22K, 24K) to manage active store weights.

Purchase & Sales Management

Fast invoice generation with multi-mode payment splitting (Cash, Card, UPI, and Metal Exchange).

Old Gold Exchange

Calculates fine weight values for old gold trade-ins, deducting trade values from active sales invoices.

Girvi (Pawn) Management

Tracks mortgaged ornaments, records principal values, monitors monthly interest accruals, and handles pawn releases.

Jewellery Valuation

Combines live rate, fine weight, wastage, and making charges instantly to calculate ornament values.

GST & Accounting

Auto-generates tax ledgers, updates store cash books, and formats compliance reports for easy GST filing.

Chapter 05

The Challenge

"The core problem was valuation accuracy — every item's value depends on live gold rate, purity, and weight simultaneously."

Because gold rate feeds shift constantly, sales staff manually recalculating bills during peak hours caused significant delays and bookkeeping errors.

To solve this, I designed a high-speed local calculation engine that subscribes to live rate web-hooks. It locks active rates at the exact millisecond of checkout. This prevented concurrency bottlenecks on desktop terminals and ensured cash registers balance perfectly every evening.
