Use the Verify and Rebuild functionality for the following reasons:

• When using QuickBooks Desktop, fatal problems might occur.
• Invoices or bills that post with negative values cause discrepancies on reporting.
• The Payments to Deposit pane displays deposited payments.
• All accounts are not shown on balance sheet reporting.
• The lists are missing names.
• There are no transactions.
• Check your company file for errors with a well-data inspection.

To fix the problem, follow the steps below to Rebuild Data.

Check the information.

Select Window and then Close All.

Check the information. Select File and then Utilities. Select Data Verification. If you get the message “QuickBooks found no errors with your data,” you don’t need to do anything further.

There may already be an article on a certain error message. For precise instructions, look for it on our QuickBooks Desktop help site.

The message “Your data has lost integrity” implies that the file has been damaged. 

Data reconstruction

Select File, then Utilities, and then Rebuild Data.

You will be prompted to backup your company file; hit OK to proceed.

A business file backup is required before a rebuild since the procedure may need to remove transactions or list entries to repair the file in rare situations. A backup of your company file ensures that you have a safe copy of your company file before making any modifications.

Choose a location for your backup and then click OK at the bottom of the QuickBooks Desktop Backup box.

If you are prompted to change another backup file, choose NO. In the File name area, type a new name and save it.

If the backup fails, go to the Rebuild menu and select Cancel.

If the backup fails, select Cancel at the Rebuild prompt and contact Payroll Support for additional assistance.

The Rebuild Data utility starts as soon as the backup is finished.

Click OK when you get the message “Rebuild has completed”.
