Thanks for joining the thread, @Barb503. If you’re dealing with undelivered invoices, I’m here to help you sort this out step by step.

An email might not go through if the recipient’s email address is incorrect or there’s a temporary issue with their email server. Ensure each customer account has the correct email address to guarantee timely delivery and payment of invoices.

To resolve the problem, follow these steps:

Check the status of the sent invoice

If you sent the invoice to multiple people, we can’t identify which one failed. So, if the invoice fails for one recipient out of three, the status will read Undeliverable.

Here’s how to check if the invoice wasn’t delivered to your customer:

1. Navigate to Sales, then Invoices.
2. Look under the Status column to see if the invoice was undelivered or sent.
3. If you’re in the Invoices tab, select the Needs Attention message to see those undelivered invoices.

Confirm the customer's email address

If the customer’s email is correct but they didn’t receive the invoice, ask them to check their junk or spam folders. You can also check your email address in QuickBooks Online, as it might be causing the issue.

1. Head to Customers & leads, then Customers.
2. Select the customer who didn’t receive the invoice.
3. Click Edit.
4. Verify the email address and make any necessary edits.
5. Resend the invoice.
