How can I delete in batch bank account history found in chart of accounts?

Hi there, @sales-virtualmar.

Being able to delete multiple transactions at once in your register is an excellent idea. Right now, you can only delete one transaction at a time. I recognize the importance of this feature to your business. I  encourage you sending a feedback to add your vote for this one.

Here's how:
 

1. Select the Gear icon at the top, then Feedback.
   
2. Enter your comments or product suggestions then select Next.
3. You'll be provided a list of suggested Help articles related to your comment. You can read through them or select Skip and send message.
4. From the drop-down, choose the appropriate category, then select Send message.

In the meantime, you can look for a third-party app that can help you delete the transactions in bulk.

Be sure to let me know how else I can empower you to make QuickBooks work the way your business needs. Thanks for coming to the Community. Wishing you even more success in the future.
