I'll help you change the customer/vendor names in the sales transactions, @MKirros. This way, your transaction reports, and books are always accurate.

We can only enter and delete transactions in QuickBooks Desktop in batches. That said, modifying the client name in bulk in the sales transaction is unavailable.

In this case, I'd recommend opening the transaction one at a time and changing the name manually. I know it's time-consuming, but this is currently the best workaround.

Furthermore, read the following articles to learn how to enter numerous customer, vendor, and item names and manage customer/vendor transactions in QuickBooks:
