This article describes how your customers can access the client portal and how they can set up a password, etc.
Whenever you send an invoice or estimate to a customer, your customer will receive a link to the client portal.
By default your customers will be able to view their invoices and estimates without setting up a password on the client portal. They will also be able to pay invoices without a password.
However if they would like to store their credit card details, or make ACH payments, then your customer will need to set up a username and password for the client portal.
