Customers aren't receiving their emailed invoices

You can update your email address and advise your customer to check their junk mail, @BelindaD. Below, I'll detail the steps to address the issue with emailed invoices.

First, if you've recently transferred QuickBooks Desktop data into a QuickBooks Online company, you'll need to update your email address to ensure that the system correctly sends sales forms via email. Here’s how to do that:

1. Sign in to your QuickBooks Online account.
2. Navigate to Settings and choose Account and Settings.
3. In the Company tab, click on Edit under Contact Info.
4. Check each email address and update if necessary.
5. Select Save, then Done.

For additional solutions, refer to this article: Troubleshoot if customers aren't receiving emails from QuickBooks Online.

Moreover, an email may fail to deliver due to an incorrect email address or a temporary issue with the recipient's email server. To resolve this, confirm that the correct email address is associated with the appropriate customer. Here's how:

1. Navigate to the Sales column and click Customers.
2. Choose the customer who didn’t receive the invoice.
3. Select Edit.
4. Check the email address and edit it if needed.
5. Resend the invoice.

Once you have verified that the email address for your customer is accurate, you can suggest that they check their email's junk or spam folder for the invoice.

It's also possible that your email service provider's server doesn't provide a notification when there's a delivery issue with your e-invoices. To view the list of bounced emails with delivery errors, refer to this article: How to view the list of bounced emails with delivery errors. (Although it's a US article, the process is also applicable in the UK region)

I'll also add this resource for insights on how to handle and record invoice payments when you receive payments at a later date: Record invoice payments in QBO.
