Why is customer is missing from customer list, but still shows in sales. I've tried private browser, emptying cache, inactive list and a phone call to QB. Nothing.

Thanks for letting us know about your concern, @ssykes1.

Upon further research, I've found that there's an ongoing investigation about customers not showing in the customer list (INV-56731). Rest assured that our product engineers are currently working on resolving this issue.

That said, I recommend contacting our technical support team to be added to the list of affected users. This way, you'll receive email updates and be notified when a resolution is posted. I've included the steps below to contact our support. 

1. Sign in to your QuickBooks Online company.
2. Click the Help (?) menu.
3. Select either tab to get started:

• Assistant: In the field, enter Talk to a human. If you decide you need further help, type once again Talk to a human.

• Search: Click Contact us at the bottom part. Select Start a chat or Get a callback from the next available expert.

Also, you can check for hidden filters on the customer list. You will see a small link at the top of the page that says clear filter. This way, it will show all the data. Please see the screenshot below:

Additionally, here's an article you can review to learn how to add, edit, delete, or merge customers: Manage customers in QuickBooks Online

You can always reach out to the Community if you need help with QuickBooks. I'll be happy to help you more. Have a nice day.

None of these worked.  Customer service did not help.  Chats won’t work as the go ignored.  This is a problem many are having, how long is this going to take to get resolved? For me, it’s been over a week.  It’s unacceptable.  

Hi @ssykes1,

Welcome to the Community. Let me share some updates about the issue when viewing the customer list in QuickBooks.

The investigation is still open, and our team has not declared a specific time-frame for the complete fix. They're still working on it and conducting a further investigation because of the unusual behavior.

If there's a fix is available, it will be applied automatically to all affected accounts. This is the reason why you need to contact our QuickBooks Support Team.

Once we have an update, our team will send out notification emails. To ensure you get in touch with some successfully, please contact them within the support hours.

Our Customer Support Team is available from 6 AM - 6 PM PT (Monday - Friday) and 6 AM - 3 PM PT (Saturday). It may be the reason why you're unable to get help from the support.

You can also check this article for more details about how you can upload customers from your email, as well as other types of imports you can use in QuickBooks: Import customers or vendors from email contacts to QuickBooks Online.

Please know that I'm just a post away if you have any other questions about the features in QuickBooks. Take care.

Was this issue ever resolved? If so, can you explain how to fix the problem?
