Hello there, @CivilUnrest87. I'd be glad to help you in applying the billing rate to time imported from QuickBooks (QB) Time. 

I appreciate you sharing additional information about your concern. To further help you with this, you'll have to manually create a billable time in QB Time and then export it to QuickBooks Online (QBO) to make an invoice for the customer. Here's how:

1. Open your QB Time account and select Time Entries and click +Add Time. 
2. Next, select the name of the employee in the Team Member field. 
3. Then, input the details on the Type, Status, Time in, and Time out fields.
4. After that, choose the name of the customer in the Customer dropdown and select Yes under Billable.
5. Input the amount ($50) in the Billable rate field and add class and service items if needed.
6. Once done, click Save. 

When finished, go to the Approvals page to approve the time entry you've created. Once done, select the QuickBooks icon and choose Export All Approved Time. This will let you import the time entry to QBO.

After that, open your QBO company and select the +New menu to invoice the customer for the time. Let me guide you on how:

1. Select the +New button and choose Invoice.
2. Then, choose the customer's name.
3. From there, you'll see the Add to Invoice pop-up.
4. Click the Add button under the Billable time entry and select Save and Close.
