Every bar, melt and issue in fine weight
The Metal Book follows gold and silver from the bullion dealer to the karigar and back. Purchases, alloying, melting, issue and receipt are recorded in gross, net and fine weight, so your metal balance is one number you can trust on any day of the month.

From bullion dealer to bench, without a gap
Bullion purchase
Record bars and grain by dealer, bar number, purity certificate and rate. Fine weight is calculated on entry.
Alloying
Set your alloy recipes for 22K, 18K and 14K. The system tells you how much copper and silver to add for a target purity.
Melting register
Each melt shows input, alloy, output and loss, with purity checked against the assay or touchstone result.
Issue and receipt
Metal moves to departments and karigars with a slip. Every receipt reduces the open balance in fine weight.
Scrap, filings and dust
Scrap and filings are weighed back separately. Dust and sweeping lots are tracked until the refiner returns fine metal.
Old gold and exchange
Customer old gold and jewellers' metal on account are kept apart from your own stock, with purity tested on receipt.
One balance, checked every evening
At day end the Metal Book closes in fine weight. Vault plus benches plus refiner plus allowed loss must equal opening stock plus purchases.

Close the day
Every location shows its fine balance. Any difference is visible the same evening, not at month end.
About Metal Book
Works together with
Can we keep our own purity standards?
Yes. Standard purities from 24K999 to 14K585 and 925 silver are included. You can add your own, for example a 22K at 91.8 for a specific customer.
How is customer metal handled?
Metal a jeweller gives you for their order is held in a separate account in their name, issued against their order only, and returned or adjusted in their statement.
Do we need to type weights by hand?
No. Digital scales connected to the bench computer send the weight directly into the slip, which removes typing errors.
Bring your melting register. We will close one day of it with you.
In a 45 minute demo we load your last month of metal issue and receipt, show where every gram went by process and karigar, and leave you with the numbers.
