Turn overdue invoices into drafted follow-ups
Check a spreadsheet on a schedule and have an agent draft invoice reminders based on how late each payment is.
- What they did
- A commenter outlined an n8n setup that ties into a spreadsheet, runs on a schedule, and inspects which invoices still need payment. An AI agent then prepares reminder emails, with the message style adjusted for invoices that are 7, 14, or 30 days late. They also said a person can review the draft before any message leaves the system.
- How it went
- According to the commenter, this reduced the time spent handling each reminder from around 20 minutes to under 3 minutes. It also prevented repeat reminders after a payment was entered. They did not claim any change in collection results.
- Tips
- You’ll need to create the overdue rules and write the base email versions yourself. If you want safety, keep the final send behind a manual approval step.
Try it yourself with n8n
Build an n8n automation that runs every [day/week], checks my invoice list at [spreadsheet link], and identifies records where [status column] shows no payment after the due date. For each match, draft an email to [client email column] using a tone that fits [7 days late], [14 days late], or [30 days late]. Put the draft in [Gmail drafts/a review queue], then wait for my approval before any email is sent. If I reject it, leave it unsent and make no changes until I confirm.
Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
