3. Verify and Rebuild the Company File Data

The Verify Data utility in QuickBooks is used to detect issues, such as data consistency errors, missing transactions, etc. in the QBW file. Once this tool finds issues, you can use the Rebuild tool to fix them. Before using this tool, close all the active windows on your system. Here are the steps to use the Verify Data tool:
