Overview
Devi Jewellers operates a high-turnover retail showroom serving hundreds of families for bridal, gold, and silver purchases. In luxury jewellery, transactions demand absolute precision — from weight-based pricing and making charges to hallmarking certification tracking.
As transaction volume expanded past ₹16,00,000+ in sales, generic off-the-shelf software failed to handle specific retail jewelry requirements: real-time biometric staff verification, held orders during customer deliberation, split payment tenders, and instant Day-Book reconciliation.
Business Need
Devi Jewellers commissioned BigBytech to engineer an end-to-end, high-performance web software application that could operate on showroom desktops and tablets with sub-second responsiveness.
The Challenges We Solved
Overcoming the traditional bottlenecks of jewellery showroom retail, staff management, and tax reconciliation.
High-Value Jewellery Inventory Sensitivity
Managing thousands of distinct gold, silver, and gemstone ornaments required foolproof item-level tracking with gross weight, net weight, making charges, and hallmarking certificates.
Staff Attendance & Biometric Disconnect
Showroom floor staff attendance was logged manually, disconnected from payroll, creating attendance disputes and lacking live punch status from hardware machines.
Counter Queue Bottlenecks During Auspicious Muhurats
During Dhanteras, Akshaya Tritiya, and wedding seasons, customer queues surged. Billing delays with held bills and split payments slowed checkout to over 2 minutes per bill.
Split Payments & Dynamic Advance Deposits
Customers frequently paid using mixed tenders (cash, UPI, credit card, exchange old gold weight), causing daily cash register reconciliations to take hours after store closure.
GSTR-1 & Regulatory Compliance Overhead
Generating accurate GST tax invoices with HSN codes, TCS thresholds, and state tax partitions required cumbersome manual calculations prone to audit errors.
Security & Staff Workspace Access Control
Needed strict role-based permission gates so floor sales staff, cashier operators, and senior store accountants each had access only to their authorized financial data.
The Delivered Solution
A specialized operational ERP bridging high-speed counter POS, hardware IoT biometric attendance, and automated regulatory reporting.
Sub-Second POS Billing & Quick POS Mode
Engineered a rapid point-of-sale interface featuring instant optical barcode scanning, held orders management, split payment processing, and hotkey checkout in under 20 seconds.
Golens AM-03E Biometric Attendance Sync
Developed a real-time WebSocket listener that directly connects Golens AM-03E biometric fingerprint devices to the staff workspace, auto-syncing employee punch activity and monthly attendance.
Live Day-Book & Cash Drawer Reconciliation
Automated end-of-day store closures with an integrated Day-Book module tracking total cash in drawer, UPI settlements, card receipts, and supplier payouts with zero discrepancies.
Real-Time Jewellery Stock & Low-Stock Alerts
Unified 2,300+ jewellery products into an atomic inventory engine with automated minimum threshold alerts, SKU barcoding, and supplier purchase order pipelines.
One-Click GSTR-1, Sales & Profit Telemetry
Implemented automated sales reports, purchase GST breakdowns, profit margins, EBITDA indicators, and instant Excel exports compliant with regulatory jewellery taxation standards.
