Managing late payments is a common challenge for B2B companies. Manual follow-ups can be time-consuming and often lead to delays in receiving payments. Automating this process can save time, improve cash flow, and maintain professional relationships. This guide provides a scenario-based approach to setting up automated late payment notices using n8n, an open-source workflow automation tool.

Understanding the Scenario

Imagine you run a B2B service company. Your clients are expected to pay invoices within 30 days. If a payment is overdue, you want to automatically send a reminder email after 35 days. If the payment remains unpaid after 45 days, you want to escalate the reminder or trigger a different action, such as notifying your accounts team.

Prerequisites

  • An active n8n instance set up and accessible.
  • A database or spreadsheet with client invoices, including due dates and payment statuses.
  • Email credentials configured in n8n for sending notifications.
  • Basic understanding of n8n workflow creation.

Workflow Design Overview

The workflow involves several steps:

  • Fetching overdue invoices from your database.
  • Checking if the invoice is overdue by 35 or 45 days.
  • Sending email notifications based on the overdue period.
  • Logging actions or notifying your team if necessary.

Step-by-Step Workflow Setup

1. Fetch Overdue Invoices

Use a database or spreadsheet node to retrieve invoices where the payment status is unpaid and the due date is older than 35 days from today.

2. Filter for Specific Overdue Periods

Add a function or code node to filter invoices further, identifying those overdue by exactly 35 days or 45 days.

3. Send Reminder Emails

Configure an email node to send personalized reminder emails to clients with overdue invoices. Use data from the invoice record to customize the message.

4. Escalate if Necessary

If invoices are overdue by 45 days, trigger an additional action, such as notifying your accounts team via email or Slack.

Automation Best Practices

Ensure your workflow includes error handling, logging, and testing before deploying it in a live environment. Regularly review and update the workflow to adapt to changes in your invoicing process.

Conclusion

Automating late payment notices with n8n streamlines your accounts receivable process, reduces manual effort, and helps maintain strong client relationships. By following this scenario-based guide, you can create a tailored workflow that fits your business needs and ensures timely payments from your B2B clients.
