I’ve been using quick books for 3 years never had this issue. I’ll send an invoice to the customers email. But now they do not receive it. It’ll say sent.

I'll provide some guidance on resolving the issue of invoices not being received by your customers in QuickBooks Online (QBO), wasatchroadside.

Upon checking my resources, we have a recent investigation regarding invoices not being delivered to customers despite showing as Sent in QBO. However, this case is already closed as resolved.

If you're still experiencing the issue, I recommend contacting our customer support team. This way, they can arrange a secure screen-sharing session to determine the problem and potentially reopen the investigation if needed.

To do that:

1. Go to the Help icon.
2. Enter a brief description of your concern in the search field.
3. Select Contact Us.
4. Choose between Chat with us and Have us call you.

In the meantime, I recommend downloading the invoice as a PDF and manually sending it to your customers outside the program.

Additionally, you can create templates for recurring invoices in QBO to send them automatically to your customers on a scheduled date.

Keep in touch if you have other questions about sending invoices and we'll respond promptly to answer. Stay safe and have a great rest of the day.
