How to mass upload Bills for thousands of consultants I have to pay keeping Project tracking?

Thank you for sharing your concern here in the Community.

Importing batch bills is currently not applicable in QuickBooks Online (QBO). However, I suggest utilizing a third-party application that helps you achieve your goal.

You can search for helpful apps by following these steps:
 

1. Go to your QuickBooks Online account.
2. On the left panel, select App.
3. Under Find Apps, search for a third-party app.
   
   

I'll add this resource to guide you on how to pay your bills: Enter and manage bills and bill payments in Quickbooks Online.

Let me know if you have additional questions about importing batch bills. Feel free to go back to this thread. Have a good one.
