QuickBooks Desktop 2020 Verify and Rebuild Data Guide

Keep your QuickBooks Desktop 2020 company file healthy after sunset. Learn how to run Verify and Rebuild Data to catch and fix file damage without upgradin

As of May 31, 2023, QuickBooks Desktop 2020 has reached the end of its supported lifecycle with Intuit. While the software will continue to run offline indefinitely, you are now solely responsible for the health of your accounting data. The built-in Verify Data and Rebuild Data utilities are your primary defense against file corruption, making it essential to know how to use them effectively on your 2020 installation.

Why File Maintenance Matters on a Sunset Version

When QuickBooks processes transactions, small instances of data fragmentation or list damage can occur. On a supported version, background services and updates often mitigated these issues. On QuickBooks 2020, no such updates are coming. Running regular maintenance ensures that minor data hiccups do not snowball into catastrophic company file failure.

The process for running these utilities is identical across most QuickBooks Desktop versions, so even though you are on 2020, the standard family-wide steps apply.

Running Verify Data

The Verify Data tool scans your company file for structural damage, checking lists, transactions, and links. You should run this at the first sign of unusual behavior, such as missing names on lists, balance sheet inaccuracies, or sudden error messages.

1. Open your QuickBooks Desktop 2020 company file.
2. From the top menu, select Window and choose Close All. This ensures no background tasks interfere with the scan.
3. Navigate to File, hover over Utilities, and select Verify Data.
4. Allow the tool to run. If you have a large company file, this may take several minutes.
5. Review the results. If QuickBooks detects no problems, no further action is needed. If it alerts you that your data has failed the integrity check, you must proceed to the Rebuild Data utility.

Running Rebuild Data

Rebuild Data attempts to repair the structural issues identified by the Verify tool. Because this tool rearranges and repairs data, it requires a recent local backup before it begins.

1. With your company file open, go to File, hover over Utilities, and select Rebuild Data.
2. QuickBooks will prompt you to create a backup. Click OK and save this backup to a local folder on your computer (not a network or external drive, to ensure a smooth write process).
3. Once the backup finishes, the Rebuild utility will begin. A progress bar will appear. Do not use your computer or open other programs while Rebuild is running.
4. When the process finishes, click OK.
5. Return to File > Utilities > Verify Data and run the verification scan one more time.

If the second Verify scan comes back clean, your file is repaired. If it still fails, run the Rebuild utility a second time.

When Rebuild Data Is Not Enough

The Rebuild utility is highly capable, but it cannot fix every type of corruption. If you have run Rebuild multiple times and Verify Data continues to report failures—or if QuickBooks crashes the moment you attempt to run the utility—you need a more aggressive approach.

First, try restoring the backup you made immediately before the corruption appeared. If that is not an option, or if the backup is too old, you will need to seek out advanced data repair. For stubborn structural damage, target chaining errors, or unreadable company files, professional QuickBooks Desktop file repair can extract your good data and rebuild the damaged tables manually, getting your 2020 file back to a stable state without forcing you to upgrade your software.

Establish a Proactive Maintenance Routine

Do not wait for error codes to run these tools. Make it a habit to run Verify Data at the end of every month before closing your books. Catching a broken transaction link early is the single most effective way to ensure your QuickBooks Desktop 2020 file remains reliable for years to come.
