Invoice Payment Follow-up Starter

Workflow Preview

Description

Starter n8n workflow for small businesses, freelancers, and agencies that need consistent invoice payment follow-up logic before connecting email, Slack, CRM, accounting, or spreadsheet destinations.\n\nIt accepts a webhook payload with invoice number, customer, amount due, currency, due date, status, and optional payment link. The workflow classifies each invoice as paid, not due yet, due soon, due today, overdue, escalation, or missing due date, then returns a clean follow-up payload with priority, next step, reminder subject, and reminder body.\n\nNo credentials, private endpoints, customer data, payment processor secrets, or accounting-system field IDs are included. Import the JSON into n8n, test with the sample payload, then connect the final payload to your preferred destination nodes.
