I'm glad to provide some information on migrating data from QuickBooks Self-Employed (QBSE) to QuickBooks Online (QBO).
There isn't a direct way to convert the data from QBSE into QBO using our mobile app. You'll have to log in to your account using a browser. Then, check if you can automatically move your data. I'll show you how.
Step 1: Save your financial report.
Log in to QuickBooks Self-Employed.
Go to the Reports menu.
In the Tax details section, select a tax year.
Select Download to get a Tax Details report.
Download a report for each tax year you have in QuickBooks.
Step 2: Move your data to QuickBooks Online.
Go to the Gear icon, then Billing info.
If you see the Explore QuickBooks Online plans, select it to start the upgrade.
Click Switch plan or Choose plan for the QuickBooks Online plan you want.
Follow the on-screen steps.
Select Bring my data if you want to choose which data you move over. If you don't want to move any data and start fresh, Hit Start fresh.
When you're ready to move your data to QuickBooks Online, click To QuickBooks Online. If you see a billing info review screen, select Change plan to start.
If you're unable to see the Explore QuickBooks option, you can manually import your QuickBooks Self-Employed data into QuickBooks Online.
