Automate Cash Reconciliation with Google Sheets & OpenAI

Eliminate manual cash reconciliation headaches with this intelligent n8n workflow that automatically compares internal balances against custodian or bank balances using Google Sheets and OpenAI analysis. Perfect for finance teams who need to streamline their daily reconciliation processes and catch discrepancies before they become problems.

What This Workflow Does

This automated cash reconciliation system connects to your existing Google Sheets to perform comprehensive balance matching. The workflow fetches internal cash balances from one sheet and custodian balances from another, then intelligently matches records by account_id. When discrepancies are detected, it calculates the exact difference amounts and routes mismatched records through OpenAI for intelligent analysis and explanations. All matched records are automatically logged, while exceptions are flagged for manual review with AI-generated insights.

Key Use Cases

• Daily Cash Reconciliation: Automate the comparison between internal accounting records and bank/custodian statements
• Exception Management: Automatically identify and analyze balance discrepancies with AI-powered explanations
• Audit Trail Creation: Maintain comprehensive logs of all reconciliation activities for compliance purposes
• Finance Team Efficiency: Reduce manual reconciliation work and focus human resources on investigating flagged exceptions

Technical Implementation

Built with proven n8n nodes including Google Sheets integration for data access, merge nodes for balance comparison, and OpenAI integration for intelligent discrepancy analysis. The workflow uses conditional logic (if nodes), data transformation (set and code nodes), and scheduled triggers for automated execution. Simply connect your Google Sheets OAuth2 credentials, point to your internal and custodian balance sheets, ensure proper account_id matching, and configure numeric balance fields (internal_balance and custodian_balance).

This ready-to-deploy solution helps finance teams transition from error-prone manual processes to reliable automated reconciliation, complete with AI-enhanced exception reporting for faster resolution of balance discrepancies.
