Hi there, @gene24.
The system sends late notices when the auto-reminder feature is set to email customers after the due date. To stop this from happening, you can adjust the reminder a few days before the due date. I can show you how.
- Open your QuickBooks Online account, then select Account and Settings from the Gear icon.
- Tap on Sales at the left pane, then go to the Reminders section.
- Enable the Automatic invoice reminders, then set the reminder a few days before the due date.
- Hit Save, then Done.
If you wish to turn off the invoice reminders, disable it by clicking the button beside the Automatic invoice reminders section.
To learn more about this feature, feel free to open this article: Automate invoice reminders in QuickBooks Online.
If you're using QuickBooks Online Advanced, you use this link as your guide: Use workflows in QuickBooks Online Advanced to send reminders.
Just in case you need additional help while emailing or printing your forms, you can as well read the instructions from here.
Please let me know how else I can help you succeed with QuickBooks. I've got your back and am always happy to help. Thanks for coming, keep safe!
