How do I delete customers? I've changed their email but invoices are still going to old email so I want to reenter everything under new client.

Thanks for notifying us about your current situation in the Community space, @tmuschiatti.

We recognize the urgency of this matter and want to ensure you can get through this as soon as possible and have your invoice sent to your customer's updated email address. Upon checking here on our system, there were no ongoing investigations or cases similar to your situation. It may have something to do with your browser as it accumulates temporary internet files that can affect your browsing experience. 

To rule out the possibility of being in this situation, you can perform browser troubleshooting. But before doing so, you'll want to sign out of your account and then access your company file in an incognito or private browser. You can use these shortcut keys to access an incognito browser:

• Chrome: Ctrl+Shift+N
• Firefox: Ctrl+Shift+P
• Safari: Command+Shift+N

Once you're in, try to edit your customer's email address. If it works and you're able to get through, you can proceed to clear your browser's cache. Refer to this article for the steps: Clear cache and cookies to fix issues when using QuickBooks Online.

You can also use other compatible browsers if the issue persists. Refer to this article to see the list of compatible browsers in QuickBooks Online: Other browsers.

If it persists, we'd recommend contacting our Customer Care Team so they can access your account in a secure environment and conduct further investigation to determine the root cause of this problem. See this page for more details: Contact QuickBooks Self-Employed Support.

Moreover, here are some articles we recommend you checking out to help you manage invoices and ensure your data stays accurate inside the program:
