Automatic Quickbooks Inventory Update from FTP

I have 2 inventory files listed on an FTP that I need to track periodically. Here are details you need to know: - Stock updates need to be integrated with Quickbooks Pro 2011 - Stock updates are required every 3 hours. - 1 of the reports has duplicate SKUs (for multiple warehouses) - highest quantity for each SKU must be selected. - Files are compressed in .ZIP format with the containing .TXT file using | as the separator. - Multiple inventory reports with different parameters - customized settings are required (for FTP location and column mapping).
