Forecasting Purchasing: Setting Up A Spreadsheet That Will Allow Me To Look At Previous Orders And Forecast

how I would go about setting up a spreadsheet that will allow me to look at previous orders and forecast what I need to buy. He never got into trouble for ordering too much, but he did get caught on ordering too little. I am thinking something along the lines of the attached. However, if anyone is using something that looks or works better (or those who solve this little problem have done a better looking or working sheet) let me know.

There will be some Vlookups that need to bring in description and price (or some other function if there is a better way to do it). The min need and max need will be populated and brought in by vlookup. The order column should be where the forecasting happens based on previous orders. I am willing to have all the data in the same workbook. The second or third sheet can be used to store data in what ever format that is needed to be done.
