Managing credit invoice follow-ups can be time-consuming and prone to errors when done manually. Automating this process helps ensure timely communication with clients and improves cash flow. In this article, we will walk through how to set up an automated system using n8n, an open-source workflow automation tool, and Xero, a popular accounting software.

Prerequisites

  • An active Xero account with access to invoices
  • An n8n instance set up and running (self-hosted or cloud)
  • API credentials for Xero (client ID and secret)
  • Basic knowledge of n8n workflows

Step 1: Connect n8n to Xero

First, you need to connect n8n with your Xero account to access invoice data. In n8n, go to Credentials and create a new credential for Xero. Enter your API client ID and secret, then authorize n8n to access your Xero data.

Create an OAuth2 Credential in n8n

Follow the prompts to authenticate with Xero. Once completed, you will be able to use this credential in your workflows to fetch invoice data.

Step 2: Fetch Overdue Credit Invoices

Set up a workflow in n8n that periodically fetches invoices from Xero. Use the HTTP Request node or the dedicated Xero node to retrieve invoices with specific criteria, such as status 'Overdue' and type 'Credit Note'.

Configure the Fetch Node

Filter invoices where the due date has passed and the invoice remains unpaid. You can add parameters to narrow down to only credit invoices needing follow-up.

Step 3: Automate Follow-up Email Creation

Once overdue credit invoices are identified, create personalized follow-up emails. Use the Set node to compose email content, including client name, invoice number, and amount due.

Design the Email Template

Include a friendly reminder, payment instructions, and a link to the invoice in Xero. Automate the email sending process with the SMTP node or integrate with an email service like SendGrid.

Step 4: Log Follow-up Activities

Track each follow-up attempt by creating a log entry in a Google Sheet or a database. Use the Google Sheets node or HTTP request node to record details such as date, client, invoice number, and follow-up status.

Step 5: Automate Workflow Scheduling

Schedule your n8n workflow to run daily or at your preferred interval. Use the Cron node to trigger the process automatically, ensuring consistent follow-ups without manual intervention.

Conclusion

By integrating n8n with Xero, you can streamline your credit invoice follow-up process, reduce manual effort, and improve cash flow. Regular automation ensures no overdue credit notes are overlooked, enhancing your financial management efficiency.
