Jewelry ERP that understands weight, purity and stones
Jewellery is one of the hardest industries for generic ERP. A ring is not just a product with a price — it is a quantity of metal at a specific purity, priced on today's rate, plus stones with their own weights and grades, plus making charges, plus wastage. Stock must be tracked by piece and by weight, and metal given to artisans must be reconciled to the gram.

Context
ERP in jewelry
We implement jewellery ERP with these concepts built in, so pricing, inventory and job work reflect how the trade actually works.
01Operational challenges
What usually breaks before the ERP project starts
01
Weight-based inventory
Stock valued by gross weight, net metal weight and purity, not just piece count.
02
Daily metal rate pricing
Prices recalculated as gold and silver rates move, often more than once a day.
03
Karigar and job-work reconciliation
Metal issued to goldsmiths and returned as finished items with losses that must be accounted for.
04
Memo and consignment stock
Goods out on approval with retailers or customers, easily lost track of.
02Core flows
How the ERP should handle each part of the business
- Sales flow
- Selling price calculated from metal weight × current rate × purity, plus stone value, making charges and taxes. Old gold exchange accepted against new purchases. Wholesale sales by weight; retail by tagged piece.
- Procurement
- Bullion, findings and stones purchased by weight and quality; certified diamonds tracked with certificate numbers.
- Inventory
- Each tagged piece has gross weight, net weight, purity, stone details and barcode. Loose metal and stones tracked by weight and lot.
- Warehouse
- Vault and showroom locations; strict counting with weight verification; transfers between branches by tag.
- Manufacturing
- Design-based production orders; metal and stones issued to karigars or departments (casting, setting, polishing); returns weighed with loss tracked by stage.
- Accounting
- Metal accounts maintained in weight as well as value; making charges and wastage costed; inventory revaluation for metal price movements where policy requires.
- CRM
- Customer purchase history, preferences, anniversaries and saving schemes for retail jewellers.
03Industry workflows
Workflows specific to jewelry
01
Rate-based pricing
Metal rates updated centrally, recalculating tag prices and quotes.
02
Karigar issue and receipt
Metal issued by weight, items received back with net weight and allowable loss checked.
03
Memo (approval) stock
Goods sent on memo tracked by customer, with conversion to sale or return.
04
Repairs and custom orders
Customer items received for repair or remodel tracked with photos, weights and job status.
04 — Reporting
Reports that should come out of the system, not a spreadsheet
- Metal balance by purity, location and karigar
- Stock by weight, piece and value
- Loss/wastage by karigar and process
- Memo stock outstanding by customer
- Sales margin including making charges
- Aged stock by design
05 — Compliance
Compliance considerations
Hallmarking requirements, certified diamond documentation, anti-money-laundering obligations for high-value cash sales, and tax rules on metal and making charges vary by country. Recording certificates and customer identity where required supports compliance.
Regulatory requirements vary by jurisdiction. We configure the system to support your obligations; confirm specific rules with your auditor or compliance advisor.
06 — Integrations
Systems the ERP needs to talk to
Metal rate feeds, barcode and RFID tag printers, weighing scales, eCommerce for online catalogues, and certificate lab databases are common integrations.
07AI opportunities
Where AI is genuinely useful here
Practical uses that sit on top of clean ERP data. None of them replace getting the core transactions right first.
01
Certificate capture
Read diamond certificates and record grading details against stones.
02
Design search
Find similar designs in the catalogue from a customer photo for custom orders.
03
Customer engagement
Draft personalised messages for anniversaries and scheme reminders.
08ERP modules
Modules a typical deployment includes
- M01Inventory (Weight & Purity)
- M02Sales & POS
- M03Manufacturing
- M04Subcontracting

09Roadmap
Implementation roadmap
- 01
Item and weight model
Define how metal, purity, stones and tags are represented.
- 02
Pricing and sales
Rate-based pricing, POS and wholesale flows.
- 03
Manufacturing and karigar
Job work issue/receipt with loss control.
- 04
Memo, repair and channels
Consignment, repairs and online catalogue.
10Common mistakes
Mistakes we see repeatedly
01
Piece-only inventory
Ignoring weight and purity makes valuation and reconciliation impossible.
02
Manual rate updates per item
Rates must update centrally, not tag by tag.
03
Loose control of job work
Without weight reconciliation at each return, losses go unnoticed.
04
Generic ERP without extension
Most platforms need extension for jewellery-specific logic; plan for it.

FAQ
Frequently asked questions
Can the ERP price jewellery from the daily gold rate?
Yes, with pricing logic that combines current metal rates, net weight, purity, stones and making charges. On most platforms this requires a tailored extension.
Can we track stock by both pieces and weight?
Yes. Tagged items carry weights and purity, while loose metal and stones are tracked by weight.
How is karigar job work handled?
Metal issued by weight is tracked against each karigar, and finished items returned are reconciled with allowable loss.
Do you support memo stock?
Yes, memo or consignment flows track goods out on approval by customer until sold or returned.
