QuickBooks Desktop

Create a verified local backup (.QBB) before touching anything. Store it in a location outside the normal working directory — on a network drive or external storage. This is your permanent audit record and cannot be recreated after migration.

QuickBooks Desktop 2020 or later migrates cleanly via Intuit's built-in export tool. Older versions must be upgraded to QBD 2020 at minimum before starting — the migration tool does not support end-of-life versions.

QBO has a target count limit of approximately 750,000 combined transactions, customers, and vendors. Before migrating, run the Company File Diagnostic in QBD:

• Go to File → Utilities → Verify Data
• Review the transaction count summary
• If near or over the limit, archive historical data or consider a clean-start migration with opening balances only

A clean source file produces a clean migration. Before exporting, complete the following:

• Merge duplicate customers, vendors, and accounts
• Reconcile all bank and credit card accounts through the cutover date
• Clear or write off old, uncleared transactions
• Remove inactive items that are no longer needed
• Run the Condense Data utility if file size is excessive

Create a second verified local backup (.QBB) after cleanup is complete — before initiating the export. Store it alongside your initial backup. Having a pre-export snapshot separate from your pre-cleanup snapshot protects you in both directions.

Not everything transfers automatically. Plan for manual re-entry of the following after go-live:

• Payroll history & settings — must be reconfigured in QuickBooks Payroll
• Inventory assemblies — convert to simple inventory items before migrating
• Custom invoice & estimate templates — will need to be rebuilt in QBO
• Memorized reports — must be recreated manually
• Fixed asset manager data
• Loan manager records

Select the plan that matches your operational needs before provisioning the QBO account:

1. Open your QBD company file
2. Go to Company → Export Company File to QuickBooks Online
3. Sign in with (or create) your Intuit account
4. Select or create the target QBO company
5. Choose whether to include inventory (see warning below)
6. Click Export — this takes 15 minutes to several hours depending on file size

Intuit sends a confirmation email when the export is complete. Do not close the QBD file during the transfer. If the migration fails partway through, Intuit support can run a clean re-import against a blank QBO company — do not attempt to retry against a partially populated company.

Run all of the following in both QBD and QBO as of the cutover date. Every total must match before go-live:

• Balance Sheet (as of migration date)
• Profit & Loss (year-to-date through migration date)
• Accounts Receivable Aging Summary
• Accounts Payable Aging Summary
• Trial Balance

QBO may automatically rename or consolidate account types during migration. Verify:

• All accounts are present and correctly typed
• Opening balances match QBD exactly
• Parent/sub-account relationships are intact

Check for duplicates, missing records, and unmapped payment terms or tax codes. Pay special attention to:

• Customers with open balances
• Vendors with open purchase orders
• 1099 vendor flags — must be manually re-enabled in QBO

QBO bank connections are not transferred and must be set up from scratch in the new instance:

1. Go to Banking → Link Account
2. Search for and connect each financial institution
3. Set the start date to the day after your last reconciled period in QBD to prevent duplicate transactions

• Payroll: Reconfigure QuickBooks Payroll or reconnect your third-party provider
• Recurring transactions: Recreate memorized templates in QBO
• Invoice templates: Rebuild under Gear → Custom Form Styles
• User access: Invite team members and assign roles under Gear → Manage Users
• Third-party integrations: Reconnect all apps from the QBO App Store

Once QBO is fully validated and live, set a closing date and password in QBD under Company → Set Closing Date. Archive the QBD file — do not delete it. It remains your permanent historical audit record.
