WP-Invoice How to create a customer log on page?

WP-Invoice is a free plugin and very limited documentation. I am testing to see if suitable for my client before I purchase their premium plugin. Not even certain if it is necessary to do that.

Is there a way to create a customer [subscriber] log on so the customer can view invoices and past payments?

Hoping someone out there may have used this plugin and knows more about it than me!
