Hi there. I recommend reaching out to our Live support team to further check on why your invoices are missing after upgrading from QuickBooks Self-Employed. They can also guide you on the next steps to do.

Follow the steps below:

1. Click the Help (?) icon.
2. Navigate to the Assistant 
3. Enter a question or topic you need help with.
4. Respond until you reach the option to chat with our Live support team.

Be sure to review their support hours to know when agents are available for assistance.

After upgrading your subscription and canceling QuickBooks Self-Employed, your account will remain accessible in view-only mode for one year. However, you won’t be able to make any changes or add new transactions, including closing invoices or marking them as paid.
