Dropshipping catalogues arrive with an RRP that looks official but is not. For some brands it sits far above what the item really sells for, for others below it. Work from that number and you either sell nothing or lose money on every order. BrandsMarketCalc measures the gap. You look up what three real items sell for in each brand, and the app works out the factor and applies it across the catalogue. It never goes below your break-even and never above the supplier's own figure.

• Work out one factor per brand from what three real items sell for
• Shoes, bags and clothing can each carry their own factor within one brand
• Never goes below break-even, with your VAT, fees and shipping included
• Never goes above the supplier's own figure unless the market says otherwise
• Updates a whole brand in one run, and stops the moment you say so
