You can add as many addresses as you like to your customer contact. You can do this while you are in the process of creating a new customer or going to the customer database to edit an existing customer's information.
Scroll down to the address section in your customer's profile tab. Click the '+' button above the current address(es).
A blank address field will appear. Enter the new address information as you normally would. Using the google verified address is recommended, if the address has a unit number or letter it is best to add a '#' before as google maps needs this to differentiate.
Make sure to check the Set as billing box if this will be used as the billing address and finally hit add. You may add as many addresses to a customer as you need, by repeating this process.
Once you have entered the address, it will appear below the map, to get a street view of the address in the map, click on the address for it to populate. You also have the option to delete an address by clicking the three dots on the far right hand side and choosing delete.
