It compares each transaction against an approved supplier list to detect unauthorized (maverick) spending. When a violation is found, AI generates corrective recommendations, alerts are sent via Slack and Email, and the incident is logged for tracking. If no action is taken within 2 hours, the workflow escalates the issue to management.\n\n## Setup steps:\nConnect Google Sheets and configure supplier and transaction data sources\nEnsure supplier names are standardized (lowercase, trimmed) for accurate matching\nSet up and authenticate Slack integration for real-time alerts\nConfigure Gmail credentials for detailed email notifications\nVerify all required fields (transaction_id, supplier_name, amount, etc.) exist\nAdjust the schedule trigger time based on business requirements\nTest the workflow with sample data before enabling automation\nActivate the workflow for daily automated execution"
