Automate Invoice Reminders with n8n: Notion, Gmail & Telegram

Streamline your invoice management process and ensure timely client payments with our expertly crafted n8n workflow. Designed to automate the tedious task of invoice follow-up, this workflow seamlessly integrates Notion, Gmail, and Telegram to handle overdue invoices, draft personalized reminders, and keep you informed of payment risks.

What this workflow does

• Every morning at 8:00 AM, this workflow triggers to review your unpaid invoices stored in a Notion database.
• It normalizes key data fields from Notion, determining the overdue status of each invoice.
• For each invoice, it calculates the overdue days and selects the appropriate escalation tier (1, 2, or 3) for the reminder message.
• Utilizing Anthropic Claude, the workflow generates a customized email subject and body based on the escalation tier.
• The crafted reminder is sent to the client via Gmail, and the Notion database is updated to reflect the latest reminder tier dispatched.
• If an invoice reaches the final escalation level, you receive an alert on Telegram, highlighting it as a high-risk payment.
