I have upgraded to quickbooks online and my historical amd 1 open invoice has not transferred from quickbooks sole trader. Has anyone else encountered this?

Hello there, Derek. The notification you received means that the data is in the system. The reason you can't see those invoices is due to the default view.

To view your historical invoices, navigate to All apps, then select Sales & Get paid > Sales Transactions. Look for the Type tab and select Invoices. For Dates, select All. Once the process is complete, it will display all the migrated invoices.

Regarding your one open invoice, you can confirm and search for it by following the steps above and adding the customer's name in the Customer tab. I will provide a sample screenshot below.

If that invoice does not appear after you search, you can manually create it in QuickBooks.
