How to add two or more contact information under the same customer?

Hello there,

Thanks for visiting the Community today. I'd be glad to walk you through adding two or more contact info under the same customer.

To achieve this, you'll need to use a comma to separate them each time you add more contact details. Here's how: 

1. Click on Sales on the left menu, then select Customers.
2. Choose the customer's name, then select Edit.
3. Enter the other contact details separating them using a comma, then hit Save. 

You can now send invoices to multiple emails without having to enter them each time you create an invoice. 

For future reference, you might want to consider adding a sub-customer to the main customer to track them individually. It works best when your customer has a group or organization. 

Feel free to message again if you have additional questions. I'd be around here to help.
