Compliance, without making the customer wait

Buying second-hand from the public means real paperwork. Gem Logic captures all of it on a single screen, on a tablet at the counter.

ID capture

Photograph the customer's ID and store it against the contact and the purchase.

Signatures

Both seller and buyer signatures captured digitally.

Counter labels

Print a label for the package the customer leaves with you.

Quote → approved → paid

Run a clear status flow so it's never ambiguous what stage the purchase is at.

Documents

Attach extra documents to a purchase: police books, supplier transfers, photos of the goods.

Metal purchase report

A dedicated report by family, purity, and weight — filterable by date and customer.

Buy gold the way a modern jeweler should

Try Gem Logic and run buy-back with the same calm and clarity as your sales.
