A Single Touch Payroll Solution

Key business requirements brought about by the changes included; reporting of pay events to the ATO via MessageXchange (3rd party gateway, scheduling and automatic uploading of pay events, notification on uploads status between STP service and MessageXchange and storage of transmitted data to MessageXchange for auditing purposes). To facilitate this, the STP service needed to be developed using C# and SQL server with any associated data logged and accessible from multiple databases.

Chamonix was engaged to conduct an analysis of ATO business rules, including assessing the database structure and the subsequent solution design to upload data to MessageXchange and a Dashboard interface to track progress and summary of pay events. We then oversaw the STP solution implementation and ran testing to validate that the data was successfully uploading.

The business wished to use C# as they had the in-house skillset to support and maintain it. MessageXchange (a 3rd party gateway) was selected for the purpose of uploading STP files using REST services. We created an asp web page in order to track, manage and view reports and manually send STP data to MessageXchange. This functionality allows users to select a pay period and trigger the STP process via the Dashboard. All data sent is logged in the database and notifications sent to Finance and IT as required. Some of the challenges that presented included frequent changes to requirements and formats and a low knowledge base given it was the first time the solution was introduced and HCA was among the first lot of recipients. Varying demographic locations also meant scheduling uploads across different time-zones.
