Quick Summary

In Australia, payroll typically starts with gross pay and deducts to get net pay. But for small businesses, reverse-calculating gross from net can be challenging.

This case study shows how a new reverse payroll system developed by iFour solves that problem. It helps you start with the net amount, then reverse-calculate gross values, and work your way up, making things smoother and more accurate.

Plus, it’s automated – so you save time and stay compliant with ATO rules.
