Is there a way to batch delete a large set of bills that were accidentally imported twice?

Hello, @bryna.

Thanks for taking the time to reached out to us. Allow me to address your concern, and help get this straightened out. 

As of now, you can only delete the bills transactions one at a time since doing it by batch is currently unavailable in QuickBooks Online (QBO). I can see how this future would be helpful for you in order to delete the bills conveniently, I'd recommend sending feedback directly to our product developers for consideration in the future updates. 

Here's how you can send feedback: 

1. Click the Gear Icon.
2. Select Feedback.
3. Click Next and choose Feedback under Category option.
4. Select Save. 

For additional reference, you can check this article on how to delete a bill. 

You can also contact our phone support if you need further assistance. They have the tools to do a remote session and guide you through the steps.

Here's how you can contact our phone support:

1. Sign in to your QuickBooks Online company.
2. Select Help at the top right.
3. Click Contact Us to connect with a live agent.

Please know that I'm just a post away if you have any other questions about bill transactions. I'm always here to help. Have a good one.
