Automated Invoice Reminder Workflow

This n8n workflow automates the process of sending timely invoice reminders to clients, effectively improving cash flow management. It is triggered daily and retrieves invoice data from a specified Google Sheet. The workflow filters invoices based on their due dates—alerting clients a few days before an invoice is due and following up on overdue payments. Key nodes include scheduling, reading invoice data from Google Sheets, a custom function to determine which invoices need reminders, a conditional check, and Gmail integration to dispatch personalized email reminders. This workflow is ideal for freelancers, small businesses, and agencies seeking to automate receivables and streamline payment collection, ensuring timely client payments while reducing manual effort.
