This n8n workflow automatically fetches monthly financial statements, normalizes the data, performs KPI calculations and trend analysis, detects anomalies, generates AI-powered executive insights and recommendations, creates professional reports, and distributes them to stakeholders while maintaining historical records. Key Insights Consistent data formats from accounting systems (QuickBooks, Xero, etc.) are critical for reliable normalization and analysis. AI-generated insights are only as good as the input data quality — always validate fetched statements and mappings first. Monthly scheduling ensures timely reporting; consider adding manual triggers for ad-hoc runs during testing. Workflow Process Initiate the workflow with the Monthly Schedule Trigger node (runs on the 1st of each month at 8 AM). Fetch current period financial statements (P&L, balance sheet, cash flow) using the accounting API nodes. Fetch previous period data for accurate YoY/MoM comparisons. Merge all statements, normalize formats, validate integrity, and calculate standardized KPIs/metrics using data transformation nodes. Analyze trends, variances, and detect anomalies/unusual patterns. Send cleaned financial data to an AI model (OpenAI/Claude) to generate natural language executive summaries, key insights, and actionable management recommendations. Format and generate professional HTML/PDF reports (with charts/visualizations if configured). Store the report and metrics in a database for historical tracking, post summary to Slack, and email the full report to management/stakeholders. Usage Guide Import the workflow into n8n and configure credentials for your accounting system(s), AI provider, database, Slack webhook, and email (SMTP). Map fields correctly in the normalization/validation nodes to match your source data structure. Test end-to-end with sample/historical financial data before enabling the schedule. Execute manually first via the Execute workflow button to verify each step (especially API fetches and AI output quality). Prerequisites API access to accounting system (QuickBooks, Xero, SAP, or direct database connection) OpenAI or Claude API key for insight generation Database (PostgreSQL, MySQL, etc.) with tables ready for reports and metrics storage SMTP server or email service credentials Slack webhook (optional for notifications) PDF/HTML generation tools (if using external services like WeasyPrint via code node or Make.com-style nodes) Customization Options Adjust the schedule (e.g., quarterly instead of monthly) in the trigger node. Modify the AI prompt in the LLM node to change the style/tone of summaries or add specific focus areas (e.g., cost control, revenue growth). Extend anomaly detection rules or add more KPIs in the analysis section. Change distribution channels (add Teams, Discord, Google Drive upload, etc.) by modifying or adding nodes after report generation. Add conditional branching for high-priority alerts (e.g., if major anomaly detected → immediate notification). An n8n automation workflow template by Oneclick AI Squad.
