Amazon Merchant Transport Utility

Use the Amazon Merchant Transport Utility

The Amazon Merchant Transport Utility (AMTU) is designed to make sending files to Amazon and receiving reports from Amazon as simple as dragging and dropping files into a directory. AMTU runs automatically behind the scenes, uploading files from the relevant directory to Amazon and retrieving the results of the uploads. AMTU can also retrieve order reports from Amazon.

AMTU is available to all sellers and can be used in addition to other methods of exchanging data with Amazon. Starting on April 1, 2020, Amazon will no longer accept contributions submitted using AMTU versions 2.5 or earlier. Users must install version 2.6.1 to continue using AMTU after April 1, 2020. See the AMTU 2.6 User Guide for further details.
