Metal that walks back in
Old jewellery arrives untagged, unweighed and of unknown purity, often against a purchase the customer wants to complete in the next ten minutes. It deserves a proper document, not a discount line.
Write it down before it leaves the customer's hand
The first minute is where old-gold disputes are won or lost. JewellerGen makes a receipt out of it.
- Item by item — description, count, gross weight, stone weight, net weight and declared purity.
- Photographs taken on the tablet and attached to the intake, before anything is cut or melted.
- Hallmark type recorded where there is one, so a BIS-marked piece is not tested as scrap.
- Printed receipt the customer signs, with your terms on it.
- Two routes — inside a sale as an exchange, or as a standalone purchase when they only came to sell.
Purity is a measurement, not an opinion
Declared purity is what the customer believes. Tested fineness is what you pay on, and the gap between them is where the money is.
XRF
Non-destructive, per item or per lot. The reading can be captured from the instrument and signed onto the lot rather than typed in from a screen across the room.
Touchstone & acid
Entered as a tested fineness with the method recorded, so a later query knows how the number was arrived at.
Karat meter
Same treatment: a reading, an instrument, a person and a time — attached to the lot it belongs to.
Fine weight × your buy rate, less what you deduct
Simple arithmetic, done the same way every time, shown to the customer in full. The deduction is your policy — per customer category, with an override that records who allowed it.
There is also the question the customer actually asks, which is the other way round: "what will this take off the necklace?" JewellerGen solves that backwards from a target, so the salesperson is not doing algebra on a calculator while somebody watches.
- Deduction as a percentage, defaulted per customer category and overridable with an approval.
- Charges — melting, testing, handling — with tax applied to the charge where it is due.
- Match-to-invoice reverse solve against a target exchange credit.
- Buy rate from your board, stamped onto the document like any other rate.
Illustrative figures.
Paying for it
Cash or bank
With the cash-limit warning applied and a voucher PDF produced either way.
Metal credit
Grams held to the customer's account, drawn down against a future purchase, with a statement.
Exchange
Set against the sale on the same bill, while remaining a purchase document in its own right.
TDS where it applies
194Q on qualifying purchases from a resident seller, with financial-year running totals per deductee and a 26Q-shaped report.
Resell it, melt it, or send it to the refinery
What happens to the metal afterwards is where the weight either reconciles or quietly does not.
- Resell as-is — re-tag the piece, put it on a counter, and it re-enters stock with its provenance intact.
- Melt into a scrap lot — weight in, weight out, loss percentage recorded per batch.
- Fire assay — per-lot fine weight from the assay result rather than the field test.
- Refinery consignment — a full lifecycle: sent, received, assayed, settled, with what came back reconciled against what went out.
- Old-gold register — everything taken in, by metal and by period, for the day somebody asks.
Weight has to close
Melting is the one operation where metal legitimately disappears. That makes it the one place a loss percentage has to be recorded against every batch and reviewed, not averaged away at the year end.
The document you least want edited quietly
Edit window
After settlement, changes are only possible inside a window you set — and after it, only by reversal.
Reversal needs approval
Unwinding a settled buyback is an approved action with a reason, never a delete.
Threshold alerts
A buyback above your value threshold, or one raised outside trading hours, notifies the owner as it happens.
