Thanks for trying the recommendation shared by my colleague, @Kevin B1.

If you need to delete an active project that has a balance, you'll have to move the transactions to another project, sub-customer, or customer first. First, open the project to change the details. Follow the steps below for a guide:

1. Go to Projects on the left panel.
2. Select the project, then go to the Transactions tab.
3. Select the transaction, then change it to the accurate project.
4. Once done, click Save and close to reflect the changes.
   
   
   

Afterward, you can proceed with deleting the project. Still, within the Project menu, look for the project you want to eliminate. Click the Options on the project you would like to delete and select Delete.

Also, there are a few steps that you can follow to generate the Unbilled Time and Expenses report in your QuickBooks Online account. In case you want to run it soon, just follow these steps:

1. Go to Projects on the left panel.
2. Select what project you want to pull up.
3. In the Project reports, click Unbilled Time and Expenses.
   

If the same thing happens, we can perform some troubleshooting steps:

Step 1: Use an incognito window.

It's likely a result of a browser error. This private window prevents your browser from storing additional cache files. It's also a good way to check issues caused by a full cache.

Step 2: Delete cache and temporary internet files

When Step 1 works, it's recommended to clear cache and temporary internet files to optimize the browser's performance. This will also help delete the information stored in the cache. You can also use other supported browsers in QBO.
