Thanks for letting us know, Taylor.

Invoice reminders are automatically sent if this feature is enabled or you've set up recurring transactions. Let's make sure it's turned off to prevent this from happening.

Here's how:

1. Go to the Gear icon.
2. Under Your Company, select Account and settings.
3. Click the Sales tab.
4. Select the Reminders edit pencil icon.
5. Click the Automatic invoice reminders to off.
6. Select Save and then Done.

You can follow the steps below if you use a recurring template. Here's how:

1. Go to the Gear  icon, then select Recurring Transactions.
2. Find the recurring template and click Edit.
3. In your Options section, untick Automatically send emails.
4. Select Save template.

If all the setting is turned off, you may experience some browser-related issue caused by too much cache stored on your browser. To isolate this, open your QuickBooks Online account using an incognito window. Use the following shortcut keys below:

• Google Chrome: press Ctrl + Shift + N 
• Mozilla Firefox and Microsoft Edge: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If this works, let's clean your browser's cache and cookies. If not, you can use another compatible browser. If the issue persists, I recommend contacting our QuickBooks Online Support. They have the tools to pull up your account and submit a ticket for further investigation.

In addition, you can use these links for guidance. These contain instructions on how to personalize and record invoice payments:

I'm always ready to help you if you need further assistance with invoice reminders. Keep safe and enjoy your day.
