FAQ

What do I need?

n8n (Cloud or self-hosted), a Google account (Sheets + Gmail) and an OpenAI API key. No coding.

What if a client already paid?

Mark the invoice Paid in the sheet and it's never chased again.

What does it cost to run?

n8n Cloud Starter is €24/mo (€20/mo billed yearly), and self-hosted n8n is free. AI costs are estimated at a fraction of a cent per draft. The guide shows the maths.

Refunds?

14-day refund if you can't get it working.
