Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureJewelry made from gold and silver loses money when prices lag behind the metal market. This app calculates the correct selling price for each piece from its weight, purity, and the current spot price, then applies your markup while enforcing a minimum floor price. Merchants review proposed price changes before applying them, and every change is logged so it can be reversed.
MetalRate Sync keeps your product prices in step with live gold, silver, platinum and palladium rates. Set a formula once (purity, making charge, wastage, markup, tax), preview every change, then apply it or let the app sync automatically. Every run is logged with the exact rate used. Set up a whole catalog from a spreadsheet, no SKUs needed.
