        "content": "# Workflow Documentation: Finance Monthly Report with AI Insight\n\n## Problem\n\nMany businesses struggle with manual, time-consuming financial reporting processes. This often leads to:\n* Delayed access to critical financial insights.\n* Lack of proactive decision-making due to retrospective data analysis.\n* Inaccurate or inconsistent reports due to human error in data compilation.\n* Underutilization of financial data for strategic planning.\n\n## Solution\n\nThis n8n workflow automates the monthly financial reporting process by:\n1.  **Extracting Data:** Automatically pulls transaction data from Google Sheets.\n2.  **Filtering & Processing:** Filters the data to focus on the previous month's transactions.\n3.  **AI-Powered Insights:** Utilizes OpenAI (GPT-4) to analyze filtered data and generate a summary of income, expenses, along with key financial insights.\n4.  **Automated Delivery:** Compiles the raw data (previous month's transactions) and the AI-generated insights into a well-formatted email and sends it to the designated recipients.\n\nThis ensures timely, accurate, and insightful financial reporting with minimal manual effort.\n\n## For Who\n\nThis workflow is ideal for:\n* **Small to Medium-sized Businesses (SMBs):** Who need regular financial oversight but lack dedicated finance teams or extensive ERP systems.\n* **Startup Founders:** Needing quick and reliable financial summaries to monitor burn rate and performance.\n* **Finance Managers/Accountants:** Looking to automate routine reporting tasks to focus on more strategic analysis.\n* **E-commerce Businesses:** To quickly understand monthly revenue and expenditure trends.\n\n## Scope\n\n* **Input Data Source:** Google Sheets (specifically configured for finance transaction data with 'Date', 'Category', 'Description', 'Amount', 'Type' columns).\n* **AI Model:** OpenAI's GPT-4 (requires an OpenAI API Key).\n* **Output Medium:** Email (via Gmail integration).\n* **Frequency:** Designed to run monthly (configurable via Cron trigger).\n* **Output Content:** Previous month's transaction table, total income, total expense, and 3 AI-generated financial insights.\n\n## How to Set Up\n\n1.  **Import Workflow:** Import this JSON into your n8n instance.\n2.  **Configure Google Sheets Node:**\n    * Connect your Google Sheets account credential.\n    * Update `sheetId` to your specific Google Sheet ID.\n    * Ensure your sheet contains relevant columns (e.g., Date, Category, Description, Amount, Type) in the 'FinanceSummary' tab or adjust the `range` if your sheet name/range differs.\n3.  **Configure OpenAI Node:**\n    * Connect your OpenAI API Key credential.\n    * (Optional) Adjust the prompt for different insights or output formats.\n4.  **Configure Gmail Node:**\n    * Connect your Gmail account credential.\n    * Update `fromEmail` and `toEmail` with your desired sender and recipient addresses.\n5.  **Add Cron Trigger Node:**\n    * Add a `Cron` node as the first step.\n    * Configure it to run on the desired schedule (e.g., 'every month', 'on the 1st day of the month').\n6.  **Activate Workflow:** Save and activate the workflow.\n\n**Important Notes:**\n* Ensure your Google Sheet data format is consistent for accurate filtering and AI analysis.\n* Monitor your OpenAI token usage to manage costs.\n* Consider adding error handling (e.g., sending an alert email if the workflow fails)."
