Send tone-adjusted overdue invoice reminders
According to the write-up, the builder ran n8n locally in Docker and assembled a chat-triggered AI agent powered by Gemini (gemini-2.0-flash-lite) with simple memory. It had two tools: a Data Table read (getInvoices) and a Gmail SMTP email sender. The source describes the finished workflow, which runs from one chat command and returns a JSON summary of emails sent.

Why it matters
Money tasks are tedious but high-stakes, which is exactly where a careful agent helps: it does the checking and paperwork while a person keeps the final say. It is one of 65 sightings filed under Finance on Agent Sightings (number 53 by interest), and one of 36 involving n8n.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into n8n or any similar agent and adjust the details to your situation.
Finance task: send tone-adjusted overdue invoice reminders. Tabulate numbers, mark uncertainties, and do not file, pay, or submit until I confirm.
Tip: Keep the agent in 'propose, don't pay' mode: let it gather numbers and draft messages, and approve any payment or account change yourself.
