Hello there, Chris. I'll add details about turning off transaction numbers on invoices.

As I have checked, there are no current reports about this issue. Sometimes, browsers can become overloaded with frequently accessed page resources such as cache and cookies, leading to unexpected behavior. It could be the reason why you're unable to turn off the transaction numbers on invoices.

To verify, let's open your QuickBooks Online(QBO) account in a private or incognito window to rule out the possibility of a webpage issue. You can use these keyboard shortcuts to save time:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P
• Edge: Ctrl + Shift + N

If everything looks good when using an incognito browser, clear your regular browser's cache. Otherwise, switch to different supported browsers to help narrow down the cause of this behavior.

If the issue continues, I recommend contacting QuickBooks Online Support once more. It's worth noting that they have access to specialized tools and resources that could aid in resolving your concern.

Additionally, you can run various customer reports to monitor your sales and ensure they're accurate. Then, personalize them to focus on specific accounts.
