That's a great question, Nirali. Thank you for pointing out the issue with the invoice emails. Let's review what's causing this duplication.
The issue you’re encountering could be due to either multiple scheduled invoice reminders or manual sending. In QuickBooks Online, reminders are designed to ensure timely payments, but they can be sent more frequently if settings overlap with manual actions.
Here’s what we can do to resolve this issue:
Check Reminder Settings: First, ensure the invoice reminder settings are not scheduled too frequently. You can review and adjust the schedule by following these steps:
- Go to the Gear icon.
- Under Your Company, select Account and Settings.

- In the left menu, choose Sales.
- Find the section for Reminders and review/edit the schedule to avoid sending multiple reminders within short intervals.

Coordinate with Your Team: Ensure no one sends the invoices manually if automated reminders are already in place. Maintain regular communication with your team to prevent duplication:
- Track when invoices are sent and by whom.
- Assign clear roles and responsibilities regarding the invoicing process.
Check the Audit Log: Use the audit log to see if someone has manually sent the invoice. It can help you identify if any team member has manually sent duplicate invoice emails, enabling you to address the issue and prevent it from recurring. Utilizing the audit log ensures you have a clear view of your invoicing process and enhances accountability within your team.
