Invoices are no longer being delivered to my clients. I've checked previous comments on this subject, and none of them have fixed the problem. Can anyone help?

I can see the urgency of resolving your concern, chriseacott.

The customer's email service sends a failure or delivery error notification to your email service when your invoices bounced back. Then a notification is added to the transaction stating the email delivery failed if the delivery failure error is sent to us by your email service provider. We can view the list of bounced emails with delivery errors by following the steps below: 

1. Go to the Dashboard on the left panel.
2. Under Tasks, select View the errors. (Note: The View the Errors link lists the emails with delivery errors sent through your email provider's server. In the delivery errors section, the delivery date, type, Ref No., Customer, error and delivery method are found.)

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

Next, sign in to your QuickBooks Online (QBO) account and try sending an invoice to your email or your customer's email address. If it works, we can go back to your regular browser and clear its cache. Clearing your browser's cache helps to troubleshoot and remove any outdated files that are causing the issue. After clearing the cache, our final step is to make sure you restart your browser to help us refresh the page. Alternatively, you can use a different supported browser.

We can also manually download the invoice and send them from outside of the QuickBooks program. I'll show you how.

1. Open the invoice you want to download.
2. Click the Print or Preview at the bottom of the page.
3. Select the Download and choose where you want to save it.
4. Hit Save, then Close to exit the PDF viewer.
