I can help you reflect these details on the customer’s invoice delivery address, @sanjay6.

Thanks for reaching out to the Community. I can provide instructions here so the customer's contact number and email id will be displayed.

Here’s how:

1. Select the Sales menu from the left pane.
2. Choose Customers.
3. Select the name of the customer.
4. Under Customer Details, click Edit.
5. Enter the email and the number above or below the Street detail.
6. Press Save.
