How to delete all invoices at once in quickbook self employed? it's very time consuming to do it one by one!

Hello there, arapiano.

In QuickBooks Self-Employed, we're unable to delete all invoices at once. I got your point and recognize the importance of having the ability to delete them all at once. For now, I recommend sending feedback to our product engineers. They'll evaluate your idea. Here's how:

1. Log in to your QBSE account. 
2. Click the Invoices menu.
3. Select the Create Invoice button.
4. Hit the Feedback option in the upper-right corner.

Another way is to submit your comments using the QBSE application. 

1. Open the QBSE application.
2. Tap on the Assistant icon at the bottom.
3. Type feedback in the field.
4. Choose Add a feature.
5. Enter and send your product suggestions.
