Analyze invoices and predict cash flow with Gemini, Google Sheets, Gmail, and Slack

Description

Analyze invoices and predict cash flow with Gmail, Google Sheets, and Gemini AI

What this workflow does

This workflow automates invoice processing and cash flow prediction by combining Google Gemini AI with form-based invoice capture, fraud detection, and financial reporting.

Submit an invoice through the web form, and the workflow automatically extracts key data using AI, checks for fraud risk, logs everything to Google Sheets, predicts cash flow impact, and notifies your team via Slack and email.

How it works

Invoice capture — Sales or accounting team submits invoice details through a web form (supplier, amount, due date, line items)
AI data extraction — Google Gemini AI analyzes the invoice, extracts structured data, categorizes expenses, and calculates tax amounts
Fraud risk check — Automated rules flag suspicious invoices (unusual amounts, new vendors, duplicate detection) for manual review
Financial database — All processed invoices are automatically logged to Google Sheets with full extracted data and risk scores
Cash flow prediction — A second Gemini AI chain analyzes the invoice in context of payment terms to forecast 30/60/90-day cash flow impact
Team notifications — High-risk invoices trigger Slack alerts; completed financial reports are sent via Gmail
