TradeGecko Intelligence Reports generate data based on the sale of individual variants. At this time, for the sale of Pack Size Variants, reports do not reflect the stock movements associated with individual units, only the top-level pack size variant itself. For example, if you sell ONE pack-sized variant/SKU that consists of 3 individual units, your sales report will reflect this as ONE unit sold. This is because the Pack Size version has its own unique SKU that differs from the SKU of individual unit.
