I have a customer who asked me if its possible to sent data (.csv format) of their inventory periodically using FTP (File Transfer Protocol).
Rather than uploading the listings thru a csv file you can check out Webgility as it has the function of transferring the Inventories to the Online Store (Creating the listings ,Syncing the Inventory Qty and Prices with QuickBooks Quantities or specify a rule to sync.
This should solve the problem.check out for Unify Enterprise software (Webgility).
Thanks for the advice. However the place that I am sending that data to only does so via FTP. Its actually and online classified.
