// how it works

Priced by weight, not by sticker.

Weight, purity, wastage, making charges, stones, margin and tax. The same rules across every product you point it at.

// 01 · THE RATES

Gold and silver, read fresh

Per gram or per troy ounce, refreshed daily or hourly, converted into the currency your store sells in. Every figure carries its source and the time it was fetched.

// 02 · THE BREAKDOWN

Every charge shown, line by line

Metal value, wastage, making charge, stone value, margin, tax and rounding. Open any row and the whole calculation is there, down to the amount your customer sees.

// 03 · THE STOREFRONT

Shoppers see the rate behind the price

A theme app block you add from the theme editor, no code. It shows the live rate and the last sync, and hides itself rather than state a rate that has gone stale.

// safety

Repricing a catalogue from a bad number is expensive to undo.

So the guards sit in front of every write, not after it.

rate-freshness.ts
// 01 · STALE RATES

Blocked, not guessed

A run is refused outright rather than written from a figure that is no longer current.

spike-guard.ts
// 02 · SHARP MOVES

Needs a second source

An unusual jump pauses the run until another feed corroborates it.

history.ts
// 03 · ROLLBACK

One click back

Every run is kept in History and restores each price to exactly what it was.

Frequently asked

Which metals and purities are supported? +
Gold at 24K, 22K, 18K and 14K, and silver at 999, 925, 900 and 800. Platinum is not enabled yet.
How do I update gold prices on Shopify automatically? +
Install KaratSync: Live Gold Prices from the Shopify App Store, tag the products you want priced from the metal rate, give each one its metal weight and purity, and set your formula once: purity, wastage, making charge (fixed, per gram or a percentage), stone value, margin, tax and rounding. KaratSync previews every new price with the full breakdown before anything is written, then keeps the tagged products updated on a schedule. Every run can be rolled back.
Is there a Shopify app that prices jewellery from IBJA gold rates? +
Yes. KaratSync: Live Gold Prices by Codeja Infotech uses India's IBJA benchmark rates first for stores selling in rupees, falling back to MCX and then the spot rate, and shows which source each price was built from.
Where do the rates come from? +
Through metals.dev. For stores selling in Indian rupees, KaratSync uses India's IBJA benchmark rates first, then MCX, then the international spot rate, separately for gold and silver. Stores in other currencies use the spot rate converted into the store currency. KaratSync shows the exact rate, the source and the timestamp behind every calculation, so you can always see what a price was built from.
Which weight do I enter for a product? +
The weight of the metal, not the finished piece. The live rate is multiplied directly by that number, so it should exclude stones, beads, enamel and packaging. A 12g ring holding a 2g diamond has a metal weight of 10g. The stones go in the separate stone value field, which is added as a flat amount and never multiplied by the rate.
Does it touch products I do not want repriced? +
No. A formula only applies to products carrying the tag you point it at, and only when that product has its weight and purity filled in. Everything else is left alone.
Can I stop a product going below a certain price? +
Yes. Set a minimum price on the product itself. It is an amount rather than a percentage, and leaving it blank means no floor.
What happens to my prices if I cancel? +
Nothing. They stay exactly where they are. KaratSync simply stops updating them.
Which currencies does it work in? +
Whatever currency your store sells in. Rates are converted into your store currency before the formula runs, and the app refuses to write if its configured currency and your store currency disagree.
