Hi there, all2.
Once you've turned on the Auto invoice reminders feature, it automatically sends reminders to all your customers when their invoices are about to be overdue. The option to manually exclude clients or select specific invoices from the auto-reminders is currently unavailable.
However, I suggest sending a reminder to overdue invoices manually. This way, you can choose a specific invoice from a particular customer.
I attached a screenshot below for visual reference.
For additional information, you can click this article: Automate invoice reminders in QuickBooks Online.

Please know that you're always welcome to post if you have any other concerns. Wishing you and your business continued success.
Further to this, there definitely needs to be the ability / tick box to exclude/ include customers from auto payment reminders. We have some very big customers who are generally good payers, I shudder to think we would send them a reminder whereas we have a lot of smaller customer who are not as good payers who need the prompt.
Hopefully it comes in a future update - soon.
