I can see the urgency of getting this rectified, and I want to ensure this is taken care of, Chris2023. 

Let's work together to get to the bottom of this. Another solution is let's double check your settings. It's possible that you have an Automatic invoice reminder turned on. When the Automatic invoice reminder is activated, and a due date is set. They will automatically send you email reminders to apply to the new invoices.  

However, if the Automatic invoice reminder is off, I suggest contacting our customer support team. They have the tools to pull up your account safely and help check your settings.  

Here's how: 

1. Go to the Help menu.
2. Choose Contact Us.
3. Enter your concern.
4. Click Let's talk.
5. Select Start messaging or Get a callback.
6. Type in your contact info.

Here's an article that you can read about invoice reminders that send to your customers: Send invoice reminders automatically or manually in QuickBooks Online. 

Let me know if you have other questions or concerns with invoices. I'll be around for you. Take care and have a good one.​​​​​
