Hi there, Isaiah58NH.

The Street, City, State, ZIP, and Country fields are entered as the customer's billing address in QuickBooks. Thus, for the customer that has a different shipping address from their billing address, you'll have to manually enter them in QuickBooks. 

Also, I'd make sure to pass this along to our product engineers so they can look into it and consider adding this on their future updates.

In addition, I'll walk you through on how to download the sample file. You can use this file as a reference in importing your customer information.

Here's how: 

1. Go to the Gear icon and choose Import Data.
2. Choose Customers.
3. Click the Download a sample file link.

Please see the screenshots below: 

I'd be right here if you have more questions with importing your customer's list.
