Metal IQ - Gold & Silver Assay Lab Platform

Assaying precious metal is arithmetic with real money attached. A jeweller brings in an impure piece; the lab takes a sensor reading and a specific gravity measurement, works out how much pure metal is actually present, applies the day's rate, adds a per-gram lab charge and a test fee, and hands back a figure both parties act on.

Done on paper and a calculator, that is slow and easy to get wrong — and there is no record afterwards of what was measured or charged.

It is also not purely metric. The gold trade works in tola, masha and ratti alongside grams, so any tool has to move between both without the operator converting by hand.

On top of the calculation itself, the platform had to be sellable by subscription to labs that pay by bank transfer rather than card, and secure enough for accounts tied to valuable stock.

A calculation engine for metal assay, delivered as a subscription platform with the account security that valuation work needs.

The lab workspace

Separate workspaces for gold, silver and tehlil analysis. The operator selects the contaminant being tested for — zinc, cadmium or copper, or pure — then enters the sensor reading, impure weight, specific gravity and the applied rate, with a carat adjustment control for fine correction in small increments.

The engine returns pure weight, touch, resulting carat and metal density alongside a full financial breakdown: lab charge per gram, total labour, test fee, applied rate and total amount payable.

Traditional and metric units together

Results are expressed in grams and in the units the trade actually uses — tola, masha, ratti and kaat, including ratti-per-tola — so the output is usable without anyone converting by hand.

Records and reporting

Every test is saved as a record that can be reopened, with reporting and charts across the lab's activity rather than results disappearing once the customer leaves.

Subscriptions with manual payment approval

Subscription plans with payments submitted by the customer and approved or rejected by an administrator — built for a market where subscriptions are settled by bank transfer rather than a card gateway.

Account security

Email verification, one-time verification codes with resend, app-based two-factor authentication with its own enrolment and disable flow, active session listing and revocation, and a per-user activity log. Administrators can impersonate an account to support a customer without asking for their password.

An assay that was previously worked out on paper is now a single screen producing purity, weight breakdown and the amount payable together — recorded, reportable and expressed in the units the trade reads.

Because subscriptions, payment approval and account security are part of the platform, it is sold to labs directly rather than installed and forgotten.
