Can I edit the Client Portal?

Hello,
I would like to use Zoho subscriptions for a subscription box product that is for consumers, and it is critical that the customer is able to access a portal where they can edit their payment options and make changes to their subscription. Is there any way to edit what information is shown on the Client Portal? It seems like it's really geared towards doing business with other businesses, and I need to tailor it to work for consumers. Thank you!
