To import your QuickBooks Desktop data into QuickBooks Online is manageable. Just make sure your data is clean and ready to be transferred to QBO.
You’ll want to check the file requirements by pressing F2 to determine the total target count. Your file should not exceed 350,000. If your file is more than the expected, you can reduce it by condensing your QuickBooks file.
