One n8n AI agent from the Production Agents Pack, free.

Invoice Chaser checks your Google Sheet every morning for overdue, unpaid invoices and writes the reminder into Gmail as a draft. The tone escalates with how late the invoice is: a polite first nudge (1-14 days overdue), a firmer second reminder (15-30 days), and a final notice (31+ days) with your payment link added. Nothing is sent - you open the draft and hit send yourself. It skips invoices marked PAID and anything chased in the last 3 days.

What you get:

• The workflow JSON, import-ready for n8n Cloud or self-hosted (tested on n8n 2.40.6)
• A plain-English spec: what it does, what it needs, and how to set it up in about 5 minutes
• A sheet template with the exact invoice columns it uses

This is 1 of the 8 agents in the full Production Agents Pack ($39): Lead Research, Outreach Drafter, Inbox Triage, Follow-up Engine, Meeting Notes, Content Repurposer, Invoice Chaser, and Agent Monitor. The full pack also includes a deployment guide, the Agent Ops monitoring sheet, and a client proposal one-pager.
