Overview
Chasing overdue invoices is one of the most uncomfortable and time-consuming parts of running a service business. This automation handles the entire follow-up sequence — a friendly reminder at 7 days, a firmer notice at 14 days, and a final notice at 30 days. QuickBooks Online has built-in reminder functionality, but this guide shows you how to customize it fully and integrate it with Gmail or Mailchimp for more professional branded communications.

Step-by-step guide (4 steps)
Enable QuickBooks automatic reminders
In QuickBooks Online, go to Account and Settings > Sales > Reminders. Toggle on automatic payment reminders and customize the timing (7 days before due, day of, 7 days after, etc.).
QuickBooks allows up to 3 reminder rules. Set them at: 7 days before due (friendly heads-up), on due date, and 7 days overdue.
Customize your reminder email templates
Click 'Edit' on each reminder to customize the subject line and body. Use a warm but professional tone for early reminders and a firmer tone for 30+ day overdue notices.
Set up Zapier for advanced follow-up (optional)
For more control, use Zapier to trigger off overdue invoices in QuickBooks and route them through Gmail or Mailchimp, giving you full branding control and tracking.
Add a late fee automation (optional)
Use Zapier to automatically add a late fee line item to invoices that hit 30 days overdue — this is a strong incentive for clients to pay on time.
Disclose your late fee policy in your contracts before implementing this.
