how do I export my details and datsa from my self-emp[lyed account to my sole trader account?

You can export transactions by running financial reports from the Reports menu or download them directly from the Transactions menu, @AJW14. Let's get into the details.

You can automatically or manually switch from QuickBooks Self-Employed (QBSE) to QuickBooks Sole Trader. Since you've already subscribed to QuickBooks Sole Trader, you can do the manual method.

First, download all your QuickBooks Self-Employed transactions and copy them to QuickBooks Sole Trader.

To run financial reports:

1. In QuickBooks Self-Employed, go to the Reports menu.
2. Find the report you want to download.
3. Select the time period or tax year from the dropdown.
4. Click Download.
5. Select the dropdown icon▼ and then the Print or Download.

If you want to export it through the Transactions menu, here's how:

1. Go to the Transactions menu.
2. Use the Type, Account, and Time period ▼ dropdowns to sort the transactions.
3. Select the Export icon.
