Inventory/Cost control Program

You will create a program that will keep a running tally of inventory. It will need to recognize and convert scanned invoice sheets into workable format. It will take note of product prices from invoice slips and items with fluctuating price it will take the average. At the end of the day I will import my sales from another program so I will know what my cost % is. It will be installed on Desktop and PDA for ease of month end inventory.
