Flat file feeds are useful when you have many different products that you want to list. You can enter all of your products into an Inventory File Template and upload them all at once instead of locating them on Amazon and listing them individually. The file you create can be retained and used to update quantities, prices and add or delete products. You can learn more about flat file feeds by going to Inventory File Templates.

If you use one of the Inventory File Templates to list your FBA products, there are several fields that must be completed correctly to list your products for Fulfilment by Amazon. If you enter the wrong information, your FBA listings will revert to listing as being fulfilled by merchant.
