I cannot access the Invoices when opening the programme on the website, but the app is ok. What happened?

I can share some information about those missing invoices in QuickBooks Self-Employed (QBSE), patrickpellin

There's an ongoing issue with missing invoices in QBSE. Our Product Engineering team is already aware of this and is now working on a fix. In the meantime, I suggest contacting our Customer Support Team, so you'll be added to the list of affected users and receive an email notification once we resolve the issue. 

You can reach our Customer Support for QBSE by going to the Assistant menu at the top right of the account. Then, let them add you to Investigation No. 87908.

Here's how to reach them:

1. Go to the Assistant menu from the top bar.
2. Enter Talk to a human and select I still need a human.
3. You'll now be provided with support options that are available at that time.

You can check this article for more information about the different types of support we offer and their availability: Contact QuickBooks Self-Employed Support.

I'm always here if you need further help with your account. Let me know by leaving a reply below. Keep safe, and have a wonderful day!
