You can turn off reminders for a recurring invoice by editing it and unchecking its automatic emails option.
 

Here's how:
1. Use your Gear (⚙️) icon, then go to Recurring Transactions.

2. Find the recurring template and click Edit.
3. In your Options section, untick Automatically send emails.
4. Select Save template.

Now your customer won't get automated notifications and other invoices will stay as they are.
 

You'll be able to find many resources about using QuickBooks in our help article archives.
