Is there a way to have someone approve Vendor Bills using QBO?

I am not sure there is any approval policies in QuickBooks yet (including in the latest update of Online Bill Pay service). You have to use an AP app to get the feature and integrate it with QBO. There are many options in market.

Yes, there is, ljohnsenita.

You can set up a user with limited access to vendors and purchases. This type of user can enter bills, pay bills, and many more. You can learn more about that here: Learn about user types in QuickBooks Online. Then, go directly to Limited (Vendors and purchases).

Here's how you can add the user:

1. Go to your Manage Users screen.
2. Select Add user.
3. Select Standard user, then select Next.
4. Select Limited, then check Vendors. Click Next.
5. Enter new user’s name and email address, then select Save.

I'll be right here if you got additional questions about user access in QuickBooks.
