I use independant contractors and have them enter their time in Quickbooks. How can I change their billable rate?

I've got the steps you're looking for, rbalgowa.

You can modify the billing rate by following the steps:

1. Go to Expenses > Vendors.
2. Look for the contractor's name and select it.
3. Click the Edit button located in the upper right corner.
4. In the Vendor Information window, change the Billing rate.
5. Click Save.

Here's a sample screenshot for a visual guide:

Please let me know if you need anything else. I'm just a few clicks away. Have a good day!

That worked. Thanks.
