An import-ready n8n workflow that checks your invoice sheet every morning, picks the right reminder tone by how overdue each invoice is, and sends it — logging every send and pinging you on Telegram. No code. Dry-run mode included.
Every operational detail is already handled — you plug in keys and run.
Runs every morning, scans your invoice sheet, and only acts on unpaid, past-due rows.
Gentle at 1 day, firm at 7, final notice at 14 — the right nudge at the right time.
Every reminder is appended to a log tab, so you have a paper trail and no silent duplicates.
Get one summary each morning of what was sent — see it without opening a dashboard.
Flip one switch and run a full pass with zero emails sent. Your first real run can't embarrass you.
Gmail SMTP + Google Sheets + Telegram are all free. Self-hosted n8n is free too.
Download from Gumroad, drag into your n8n instance. One minute, no node-wiring.
The README points at every field — Google Sheets, Gmail SMTP, Telegram, your sheet id.
Validate on dummy rows, then flip to live. Overdue reminders start going out on schedule.
No. Import the JSON, paste your API keys where the README tells you, and run. The workflow is pre-built — you're configuring, not coding.
Three tones by how overdue the invoice is: a friendly reminder at 1 day, a firmer nudge at 7, and a final notice at 14. All copy is editable in the workflow.
Yes — agencies and freelancers deploy it for clients all the time. One license per deployment; email for bulk arrangements.
Every template ships with dry-run mode on dummy data and a 30-day satisfaction promise. If it doesn't do what the page says, email within 30 days for a full refund.
Import the workflow, plug in your keys, and let overdue invoices chase themselves.
