πŸš€ What This Workflow Does

This automation helps small business owners track income and expenses effortlessly, turning scattered emails and WhatsApp messages into structured financial data β€” all without manual entry.

Every month, it:
Pulls receipts and invoices from your Gmail and WhatsApp
Uses AI to extract key details (date, vendor, amount, category)
Logs everything into Google Sheets
Generates a monthly cash flow forecast with visual insights
Sends you a clear, concise email report with AI-powered recommendations

No more spreadsheet stress. No more missing receipts. Just financial peace of mind β€” delivered every month.

πŸ’‘ Why It Matters

As a small business owner, your time is too valuable to spend manually logging transactions. This workflow automates the entire finance tracking loop β€” from receipt capture to insight delivery β€” so you can:
Know exactly where your money is going
Spot trends and plan ahead

Start each month with confidence

It's soft tech at its best: simple, elegant, and deeply useful.
