how to stop auto reminders for certain customers in Quickbooks?

The Automatic Invoice Reminders feature is an all-or-nothing setting. This means that we're unable to turn it off for just one specific customer profile.

If the invoice has not been sent yet, a quick workaround is to temporarily remove the email address from the customer's account to block the reminder. See this article for a step-by-step guide: Edit customer info in QuickBooks Online.

If the invoice has already been sent, your best bet is to temporarily change the due date. Because reminders are triggered by that exact date, moving it will stop the notification from being sent. Just remember to change the due date back once the invoice is paid to ensure your financial reporting remains accurate.

Don't hesitate to ask follow-up or new inquiries if you need anything else.
