Can I get my account set to auto assign the correct sales tax rate to each county that we provide services? So far it assigns the sale tax rate of my companies address

Hi there, ArrowheadPT.

Sales tax in QuickBooks Online is automatically calculated based on the following:

• Your customer’s tax-exempt status
• Where you sell and where you ship
• What you sell

In some states, when you sell or ship to a different address, sellers are required to charge sales tax based on business location. 

For your situation, you'll want to manually change the Location of sale on each transaction with a different address. This will update the sales tax calculation in the transaction. Here's a sample screenshot of an invoice for a visual guide:
