Automated QuickBooks Payment Reminders with Dynamic Invoice Tables

This workflow provides a powerful solution for businesses using QuickBooks Online to automate their payment reminder process. It solves the time-consuming and manual task of chasing late payments by creating a fully automated system that ensures every customer with an outstanding balance receives a timely, professional, and consolidated reminder email.

The workflow periodically fetches all unpaid invoices from your QuickBooks account. Its core strength lies in its ability to group multiple outstanding invoices for a single customer into one email, presenting them in a clean, easy-to-read table. This improves clarity for your customers, reduces email clutter, and significantly increases the likelihood of prompt payment.

This template was crafted with care by the team at Prompt-Wizards to help you streamline your finances and build stronger customer relationships through smart automation.

How the Workflow Operates

1. Scheduler: The workflow initiates on a customizable schedule (e.g., every day at 9 AM).
2. Get Unpaid Invoices: It fetches all invoices from your QuickBooks account that have an outstanding balance greater than zero and were created within a specified date range.
3. Get Customer Wise Invoice list: This Code node intelligently processes the list of invoices and groups them by customer name, preparing the data for email generation.
4. Invoice Template: This Code node dynamically generates a beautiful, responsive HTML email for each customer, complete with a personalized greeting, an invoice table, and the total amount due.
5. Send Reminder Email: The final node sends the uniquely crafted email to the customer's billing address on file.

Prerequisites

Before you begin, please ensure you have the following:

• An active n8n instance.
• A QuickBooks Online account with API access.
• An email service (e.g., SMTP, Gmail, Outlook) connected to n8n as credentials.

Step-by-Step Setup Guide

Follow these instructions carefully to configure the workflow for your business in under 5 minutes.

1. Connect Your QuickBooks Account

You must authenticate your QuickBooks account to allow n8n to fetch invoice data.

• Select the Get Unpaid Invoices node.
• In the Credentials section on the right, either select your existing QuickBooks account from the dropdown or click Create New to connect your account.

2. Personalize the Email Template

Personalize the email to match your brand and include your payment information.

1. Open the Invoice Template node.
2. Inside the code editor, find and replace these two placeholder values:

   • Your Company Details: On line 120, find <p>Your Company Name | ... and replace the placeholder text with your real company name and address in the email footer.

3. Configure Your Email Account

You must connect the email account you want to send reminders from.

• Select the Send Reminder Email node.
