The Invoice undelivered through email

Hi there,

Glad to have you join the Community. QuickBooks allows you to streamline your work using the powerful features offered in the program. I'll be happy to share more info so you're on the right track.

To get started, I recommend checking the invoice status so you're aware of what's causing the invoice to be undeliverable. You can check this using the steps below:

1. Go to Sales, then Invoice.
2. In the Status column, you’ll see if the invoice is undelivered or sent.
   Note: If you’re in the Invoices tab, you can select the Needs Attention message to see those undelivered invoices.

I also recommend clearing cache and cookies on your browser. Clearing cache and cookies helps with fixing most browser issues. You can do this by following the steps in this article: Clear Cache and Cookies. I encourage you to give this a try on your browser when you get a chance. 

Feel free to let me know what happens. I'll be here in case you have other questions.
