Jewellery Shop Software: Weight, Purity & HUID Hallmarking Guide (2026)

Running a jewellery shop in India is unlike running any other retail business. You don't sell a fixed-price product off a shelf — you sell metal by weight, at a purity, with making charges and wastage layered on top, and a gold rate that can move before the customer even finishes browsing. Add old-gold exchange, karigar (goldsmith) metal accounts, mandatory HUID hallmarking and 3% GST, and it becomes clear why generic billing tools simply cannot keep up.

This guide explains what jewellery shop software actually needs to do in 2026, how each piece works, what it costs, and how to choose a system that fits a real showroom rather than a spreadsheet dream.

Why jewellers need purpose-built software

Most off-the-shelf billing apps assume a product has one price. Jewellery doesn't. A single ring's value is calculated live from the gold rate, its net weight, its purity, making charges, wastage and stones — and the number changes daily. A generic tool forces staff to compute this by hand and type in a final figure, which is slow, error-prone and impossible to audit. Purpose-built jewellery software encodes these rules once, so the counter staff simply weigh the item, pick the purity, and the correct price appears.

Beyond billing, jewellers carry inventory that is measured in grams, not units, and that inventory is often out with karigars, on approval, or in the melting pot. Tracking metal accurately — by weight and purity — is the core problem generic software was never built to solve.

Stock by weight and purity (karat)

The foundation of any jewellery ERP is metal tracking. Every item is recorded with gross weight, net weight (after deducting stones), and purity — 24K, 22K, 18K, 14K for gold, plus separate handling for silver, platinum and diamonds. Good software converts between purities using fineness, so you always know your true fine-metal position regardless of how the stock is described on the tag.

This matters because your real asset is fine gold. A shop might hold thousands of pieces, but at any moment the owner needs to answer one question: how many grams of pure gold do I own, and where is it? Software that maintains stock by weight and purity answers that instantly — separating counter stock, karigar-issued metal, approval stock and scrap.

Making charges and wastage

Making charges (the labour cost of crafting a piece) can be charged in several ways, and your software should support all of them because different items and different customers are priced differently:

• Fixed rupee amount per piece — common for standard, machine-made items
• Per-gram rate — most common for plain gold ornaments
• Percentage of the metal value — used for premium or designer pieces
• Wastage percentage — an additional metal weight added to account for loss during crafting

The system should apply these automatically per item or item-group, show them transparently on the invoice, and let you override at the counter for negotiation — while still keeping the audit trail of what was quoted versus what was billed.

Old-gold exchange and valuation

Exchange of old ornaments is central to Indian jewellery retail. When a customer brings in old gold, the software should weigh it, deduct for stones and impurity (or record a touch/purity test result), value it at the current buy rate, and adjust that value against the new purchase in the same bill. The exchanged metal then flows into your scrap or refining account rather than being treated as a cash discount.

Karigar / goldsmith metal accounts

Most jewellers issue raw gold to karigars (goldsmiths) who return finished ornaments. This is effectively a metal loan, and it must be tracked by weight and purity — not money. The software maintains a running metal account per karigar: gold issued, ornaments received, wastage allowed, and the outstanding metal balance. It should also record making charges payable to each karigar so labour settlement and metal settlement are both accurate.

Without this, shops rely on paper chits and memory, which leads to disputes and quiet metal leakage. A karigar ledger that shows exactly how many grams are out and with whom is one of the highest-value features in a jewellery ERP.

HUID and mandatory BIS hallmarking

Since the phased rollout that began in June 2021, hallmarking of gold jewellery with a six-digit alphanumeric HUID (Hallmark Unique Identification) is mandatory across notified districts in India, enforced by the Bureau of Indian Standards (BIS). In practice this means jewellers can only sell hallmarked gold jewellery carrying the BIS mark, the purity/fineness grade, and the unique HUID.

Good jewellery software supports this end to end: storing the HUID against each piece, printing it on tags and invoices, and letting staff look up or scan the HUID at the point of sale. It keeps your billing consistent with what is physically stamped on the ornament, which matters both for customer trust and for any BIS inspection. Always verify current hallmarking rules and notified areas on the official BIS portal, since the scope has expanded over time.

Gold-saving schemes

Monthly gold-saving schemes are a major footfall driver. Customers pay a fixed instalment each month and redeem the accumulated value (often with a bonus instalment) against jewellery at maturity. The software should manage scheme enrolment, track instalments and receipts, calculate the maturity benefit, and convert the final value into a purchase — all without manual registers. Clean scheme accounting also keeps you on the right side of the deposit rules that govern such plans.

Barcode, RFID and tagging

Barcode or RFID tags let staff pull up an item's weight, purity, making charge and HUID in one scan. This speeds up billing, reduces manual entry errors, and makes physical stock-taking far faster — a scanner sweep reconciles the showroom against the system instead of a multi-day manual count.

GST on jewellery

Gold jewellery in India attracts GST at 3%, and making charges are generally taxed as well. Jewellery software should compute GST correctly on the metal value and making charges, generate GST-compliant invoices with HSN codes, and produce the reports your accountant needs for filing. Confirm the applicable rates and any updates on the official GST portal, as rates and rules can change.

Multi-showroom operations

If you run more than one branch, the software should consolidate stock, sales, schemes and karigar accounts across showrooms while still letting each branch operate independently. Owners get a single view of fine-metal position and cash across the business, and stock can be transferred between branches with proper weight-and-purity records.

Key features and the benefit each delivers

What it costs and how to choose

Wizix Jewellery ERP starts from ₹49,999. The final figure depends on how many showrooms you run, whether you need barcode/RFID hardware, the number of users, and any custom workflows specific to your business. We'd rather scope it honestly than quote a headline number that changes later — so the starting price is a genuine floor, not a teaser.

When you evaluate any jewellery software, judge it against how you actually operate, not a feature checklist. Ask these questions in order:

1. 1Does it track stock by weight and purity, not just by piece?
2. 2Can it handle old-gold exchange as metal, keeping your gram-level books balanced?
3. 3Does it maintain proper karigar metal accounts with wastage?
4. 4Does it store and print HUID, and produce compliant hallmarked invoices?
5. 5Does it compute 3% GST and generate filing-ready reports?
6. 6If you plan to grow, does it support multiple showrooms cleanly?
7. 7Is the support local and responsive, and is your data yours to keep?

In jewellery, the software's real job isn't to print a bill — it's to always know how many grams of fine gold you own and where every gram is.
