Thanks for sharing the details with me, @rhfullerton1.
I can imagine how this issue affects your business. I have some steps we can perform to isolate this issue.
There are times that the browser is full of frequently-accessed pages. Thus, it causes unusual behavior to your QuickBooks Online (QBO) account. To verify, let’s access your account on a private window (incognito).
Using a private window doesn’t store any data. Thus, this helps us determine if this is a browser cache issue. To start, you can follow these keyboard shortcuts depending on the browser you’re using.
Once logging in via a private window, try to check with your customer if they still get email reminders from you. If they haven’t, then I’d recommend clearing your browser's cache. This will delete all data and make your browser to function efficiently.
If the issue persists, try using other supported browsers. That way, we can see and check if this is a browser-integrated issue.
If you're still having the issue after performing the steps above. I’d recommend contacting our Support team. That way, you’ll be added to the list of affected issuers and be notified via email of any news and updates about the issue.
Let me also attach this article that you can read for future reference: Customize invoices, estimates, and sales receipts in QuickBooks Online. This link can walk you through the steps on how to add information to your invoice.
In case you have other concerns or questions about invoices in QBO, you can always get back to me by leaving a reply on this thread. I’ll be around ready to help you. Keep safe
The exact same thing is happening to me. On Saturday a reminder was sent to a customer and I didn't send it and the send reminder notice is at off. And again this morning to a different customer, and the invoice isn't even due yet. Very embarrassing.
Thanks for reaching out to the Community about this, LauraASH.
If you have any other users set up, it's possible they could be sending invoice reminders manually. This is done by finding the transaction and using your ▼ drop-down arrow next to Receive payment to select Send reminder. You'll definitely want to check with any user who has access to this part of your books.
In the event your employees aren't sending them, or you're the only user, you'll want to use the article my colleague provided to contact our Customer Care Team. They'll be able to pull up your account in a secure environment, conduct further research, and create an investigation ticket if necessary.
I've included a resource about managing users that might come in handy moving forward: User types & user permissions
If there's any questions, I'm just a post away. Have a fantastic day!
Exact same thing happening here. In 5 years have never adjusted a setting applying to repeatedly sending invoices to clients and now it is happening unexpectedly and sending invoices every other day.
Thanks for following this thread, HS10.
