PROJECT OVERVIEW
Manual financial tracking at the end of every month is time-consuming and prone to errors, especially when calculating total sales, expenses, profit/loss, and GST liabilities.
To eliminate manual accounting effort, we developed an Automated Expense Tracker & Monthly Financial Reporting System using n8n.

The goal was to ensure accurate, automated financial visibility without manual calculations.
