Currently, if a client does not have access to the Client Portal, when emailing the invoice, they are given a link directly to the invoice with a "Pay Now" button. This works great; it is quick, easy to use, and simple to understand.

However, if a client has the Client Portal enabled, they are given a link to the portal. This requires logging in, entering a password, clicking through to the invoice, etc. There are a lot of steps to go through.

I suggest that there be an option to include both links (for clients that have the Client Portal enabled) such as:

"Click here to view/pay your invoice" or "Click here to enter the Client Portal where you can access all of your transactions"...or similar.
