Client Management is a sub-domain of Obligation Management (OBLMGT). This page contains information and artefacts for Digital Service Providers (DSPs) who have or are interested in developing web services that enable intermediaries to manage their client’s information with the ATO. The services described below are only deployed on the SBR ebMS3 platform.
For ease of use, services have been organised into the following business processes:
- Relationships – Allows an agent or payroll provider to search for a new client, list clients with an existing relationship and add or remove a relationship at the client level, account level and/or specific role level
- Demographic Information – Allows users to list and update addresses, client details, financial institution details, authorised contacts and list associates
- Communication preferences – Allows an agent to set, maintain, view and list communication preferences for their practice and their clients. Allows a business intermediary or business client to view communication preferences
- Client communication – Allows an agent to list and view client communication.

The ATO provides a number of common artefacts and reference documents to support DSPs (such as the ATO Service Registry and the ATO Service Support Versioning Strategy). These can be found here.
