We are all spending countless hours to create transfers and purchase orders looking through the history and predicting the future, while other almost all software does it already for years. When you create a transfer you should have the option that it should be automatically filled in with the items and qty’s needed based on historical data, for example: check how much I sold of this item on Amazon in the last 30 days, and based on that I wanna have 90 days of stock, or check how much I’ve sold of this item in the last 90 days and based on that I want to create a purchase order for 9 months of stock.
