The export to desktop provides you with a local copy file that must be opened in desktop within 10 days. Exporting data to QuickBooks desktop edition or creating a local copy has several known issues.
In some cases, it would be better to just start with entering opening balances from Balance Sheet or Trial Balance (if transferring in during the fiscal year).
MUST DO: Print (and download to Excel) all major reports from QBO. Do not forget Sales Tax reports and Inventory related reports if applicable.
Do not forget to CANCEL your QBO subscription. Make sure account is NOT suspended.
