Re: How can I add multiple "ship to" locations to a single customer?
Welcome to the Community, dcmain.
There isn't an option to add multiple shipping addresses in QuickBooks Online. We can only add one per customer.
As a workaround, you can enter the additional addresses in the Notes box of the Customer information screen. This will let you save the information should you need them in the future. I'm here to show you the steps.
Go to Sales on the left pane.
Select Customers at the top to open the client's list.
Click the customer's name to open their profile and hit the Edit button at the top.
Tick the Notes tab and enter the shipping address.
