Navigate to the 'Customers' tab in the dashboard

Click "Add Customer" in the top right of the screen, it will prompt the popup in the next step

Click "Use Full Form" to fill out the customer information yourself

And enter any relevant information on the customer you have on hand

A few things to note about some of the fields:

When inputting this customer's phone number, remember to put the number '1' before the phone number or else it won't be accepted

In the 'Email' field, if the email isn't available during account creation, input 'FirstNameLastName@noemail.com'. The system will recognize it as a placeholder.

The "Accounting Email" field is optional but whatever email is inputted will be sent over any related invoicing emails to this address

When you are ready, click "Add / With email" on the bottom right to save and register the customer into the system!
