Hi there, @cw2pol.
When migrating from QuickBooks Self-Employed (QBSE) to QuickBooks Sole Trader, some transactions may not transfer automatically, particularly those dated before January 1, 2023. As a workaround, you can manually download your QBSE transactions and import them to QuickBooks Sole Trader.
Here’s how:
- In your QBSE account, go to the Transactions menu.
- Use the Type, Account, and Time period dropdowns to display the travel expense transactions.
- Select the Download icon.

To import the transactions to QuickBooks Sole Trader, follow these steps:
- In your QuickBooks Sole Trader account, go to the Gear icon and click Import data.

- Choose Bank Data on the record type dropdown and Import.

- Upload the file you downloaded earlier and Continue.
- Complete the file setup.
- Hit Got it once done.
For more details about importing transactions to QuickBooks manually, you can refer to this resource material: Manually upload transactions into QuickBooks.
