Jewellery retail has unique operational needs that generic POS systems like Marg or Vyapar fail to handle — real-time gold rate updates, making charges per design, wastage tracking, and HUID-based hallmark certificate management. We built a custom system for Nakshit Jewels and documented the decisions here.
1 Why Standard POS Systems Fail for Jewellery
Generic POS systems are built around a simple model: fixed-price item → quantity → total. Jewellery pricing doesn't work this way. The price of a 22-carat gold necklace depends on: live gold rate (updated hourly), weight in grams, making charges (flat or percentage), wastage percentage, stone charges, and GST (3% on gold, 5% on making charges — taxed differently).
None of the popular Indian POS tools — Marg, Vyapar, Retail POS Plus — handle this correctly. Shopkeepers end up maintaining a parallel Excel sheet for jewellery billing, which creates reconciliation nightmares and compliance risks.
- Gold rate must be updatable hourly — linked to IBJA or MCX rate feed
- Making charges differ per design category — not a flat percentage across all items
- Wastage percentage varies by purity (22K vs 18K) and manufacturing process
- Stone charges (diamonds, rubies) are priced independently, not by weight
- GST is applied differently on gold value vs making charges — standard POS gets this wrong
2 HUID Hallmarking Integration: A Mandatory Compliance Requirement
Since June 2021, BIS hallmarking with HUID (Hallmark Unique ID) is mandatory for all gold jewellery sold in India. Every piece must have a 6-character alphanumeric HUID that is registered on the BIS Care portal and printed on the invoice.
For a jewellery retailer with 5,000+ SKUs, managing HUID records in Excel is a compliance time-bomb. Our custom system maintains a HUID register linked to each inventory item. When an item is sold, the HUID is automatically printed on the bill and logged in the compliance record. Unsold items can be batch-verified against BIS records.
- huid_register table: item_id, huid_code, purity, weight, assay_centre, registration_date
- HUID printed automatically on sales invoices and delivery receipts
- Batch HUID verification against BIS Care API for stock audits
- HUID transfer logging when items are sent to goldsmith for modification
- Compliance report: all HUIDs sold in a date range, exportable for BIS submission
3 Customer KYC and Old Gold Exchange (OGE) Management
Jewellery businesses handle large cash and gold transactions that require KYC under PMLA (Prevention of Money Laundering Act). Any transaction above ₹50,000 requires PAN card collection. Transactions above ₹2 lakhs in cash are prohibited.
Old Gold Exchange — where customers sell old jewellery against new purchase — requires weight measurement, purity assessment, and accurate pricing. Our system manages OGE as a separate module: incoming old gold is weighed, purity tested (melting wastage estimated), net value calculated at current gold rate, and applied as credit against the new purchase invoice.
- Customer KYC module: PAN, Aadhaar, address — mandatory for transactions > ₹50,000
- Payment mode enforcement: cash transactions blocked above ₹1,99,999
- Old Gold Exchange: weight entry, estimated purity, gold rate, net credit calculation
- OGE items tracked until melted/returned — full custody chain maintained
- Form 60/61 generation for customers without PAN — auto-filled from KYC data
4 Repair & Order Tracking: The Workshop Module
Beyond billing, jewellery retailers operate a repair and custom-order workshop. Customers bring items for sizing, stone setting, polishing, or custom design work. Each job requires tracking: item description, current condition, requested work, target completion date, advance payment, and final delivery.
Our workshop module assigns each job a unique job card with barcode. The item is tagged physically with the barcode label. Status updates (received → in work → quality check → ready for delivery) trigger WhatsApp notifications to the customer automatically.
- Job card: customer, item description, photo upload, requested work, estimated delivery
- Barcode tagging: physical label on item linked to digital job card
- Status updates via WhatsApp: 'Your ring is ready for collection' template message
- Advance payment tracking: partial payment at intake, balance at delivery
- Goldsmith assignment and estimated material consumption logged per job
Key Takeaways
- Jewellery POS requires live gold rate integration, HUID compliance, and differential GST — standard tools fail
- HUID hallmark register is mandatory compliance — must be linked to every inventory item
- Old Gold Exchange module needs purity assessment, weight tracking, and credit against purchase
- Customer KYC is legally mandatory for transactions above ₹50,000 under PMLA
- Workshop job card module with WhatsApp status notifications significantly improves customer experience
