Electronic commerce interface

The electronic commerce interface (ECI) client software is an application that allows businesses with an Australian Business Number (ABN) to communicate with the ATO electronically.

Note: ECI is scheduled to close in December 2019 and the services within ECI are being phased out as they become available on the portal or in SBR-enabled software.
