How was SupplyCaddy planning before Flowlity?

Before Flowlity, SupplyCaddy ran its entire forecasting and replenishment process in Google Sheets, across roughly 250 custom packaging products. Warehouse data was disconnected from the demand sheets, so visibility rarely reached beyond thirty days, and the day-one usage numbers from new customers were often off by 5 to 30%. Planning was a manual, full-time job that grew heavier with every product SupplyCaddy added.
